Alpha
Adrenergic Agonists
- Alpha adrenergic agonists are drugs which
stimulate sites in the nervous system that respond to the chemical norepinephrine. Therefore, patients suffering from forms of incontinence
requiring increased muscle tone and urethral resistance -- for example,
stress incontinence -- may benefit from the use of alpha-adrenergic
agonists.
|
|
Alpha-1
Adrenergic Blocking Agents (Alpha Blockers)
-
Benign prostatic hyperplasia -- noncancerous enlargement of the prostate --
can encroach upon the urinary tract, leading to
overflow or
urge incontinence. Alpha-1 adrenergic receptor blocking agents --known as
alpha-1 blockers or alpha blockers -- are used to treat BPH, because they reduce
the tone of striated and smooth muscle, thereby decreasing urethral resistance
and relieving symptoms of obstruction. Alpha blockers should not be used in
people who are hypersensitive (have an exaggerated reaction) to such medication
or who experience postural hypotension (extremely low blood pressure when
standing up or standing still).

Alternative Treatment Devices
- In addition to standard methods such as biofeedback, drug therapy and
surgery, a number of treatment devices are available to help patients achieve
bladder control.
Interstim is a new therapy which may be effective in treating urge
incontinence in some patients. It consists of a device, about the size of a
pacemaker, that is implanted into the sacral nerves of the lower spine, where it
delivers electrical impulses that help regulate bladder function.
In this way, Interstim reduces the likelihood and severity of accidental
urination or leakage. The surgery required for implantation is minimal, and the
device can be adjusted to meet the bladder control needs of each patient.
Prosthetic occluding devices can be used to block the flow of urine by
squeezing the urethra shut. For men, such mechanical devices include penile
clamps (for example, the Cunningham clamp) and compression rings. The penile
clamp is a V-shaped casing with a foam cushion that fits over and under the
penis. When closed, the penile clamp should stop the flow of urine without
causing discomfort. Compression devices are adjustable rings that surround the
penis and, when inflated with air, pinch off the urine flow. Occluding devices
usually are reserved for temporary use by individuals with stress incontinence.
These devices must be removed at regular 2- to 3-hour intervals to empty the
bladder. Therefore, they should be used only by mentally competent individuals
who are able to adjust them by hand and who are able to remember the
bladder-emptying schedule. Improper use of penile clamps and compression devices
can result in penile and urethral erosion, penile edema (swelling), pain and
obstruction.
Vaginal pessaries -- ring, cube or doughnut-shaped devices made of rubber or
silicone -- are inserted into the vagina to support the bladder neck in female
patients with stress incontinence. Vaginal pessaries are available in different
sizes, and they are generally put in place by a gynecologist. The major side
effects of pessary use are wearing away of the vaginal skin and vaginal
infection. Therefore, people who use pessaries need frequent examinations to
ensure vaginal health. Erosion problems usually can be managed by removal of the
pessary until the skin heals, and vaginal infections are treatable by douching
and/or antibiotic therapy. Pessaries may be an alternative form of treatment for
frail elderly women who cannot undergo other forms of incontinence therapy.
Introl is a pessary-like vaginal prosthesis that also works to support the
bladder neck. A woman can insert and remove the device, which should not be worn
continuously for more than 24hours without proper cleaning. The manufacturer
recommends removing the prosthesis at night before going to bed.
A number of additional treatment devices recently have become available for
women. The first device--the Reliance urinary control insert--also is known as a
urethral plug. The Reliance insert is a single-use, balloon-tipped tube that is
about one-fifth the size of a tampon. The insert can be placed in the urethra by
means of a special applicator. When in place, the small balloon (which extends
into the bladder) can be inflated with air to prevent leakage. If the wearer
wishes to urinate, she just pulls a string to deflate the balloon and then
removes the insert. Unfortunately, fairly high infection rates are seen with
this device, because it is placed directly into the urethra. The manufacturer
reports that urinary tract infections are most common during the first month of
use and decrease as women become more familiar with its proper use.
Amitriptyline
(Elavil) and doxepin (Sinequan)
act as antidepressants when given in large doses. In smaller doses, they can
help IC symptoms by blocking pain, calming bladder spasms, and decreasing
inflammation.
Some cases of IC may be caused by too much histamine in the bladder.
Antihistamine drugs such as hydroxyzine (Vistaril and Atarax) and cimetidine (Tagamet)
relieve symptoms in some IC patients. If taken at bedtime, hydroxyzine may also
help patients sleep.

Androgen
receptor Deficiency
- Like 5-alpha-reductase deficiency, androgen
receptor deficiency is a genetically-linked expression of abnormal androgen
(male sex hormone) activity. And, like 5-alpha-reductase deficiency, androgen
receptor deficiency can produce a syndrome of pseudohermaphroditism (see also
5-alpha-reductase deficiency). The clinical features of androgen receptor
deficiency, also known as Reifenstein syndrome, may range from infertility alone
to pseudohermaphroditism (incomplete masculinization of the external male
genitalia in men with bilateral testes). Cryptorchidism may be present, along
with vas deferens defects and incomplete sperm production.
Patients often show high blood levels of testosterone, coupled with increased
levels of luteinizing hormone (LH) and increased secretion of estradiol (natural
estrogen) by the testes. The enhanced estradiol output leads to feminization
(development of female sex characteristics), androgen resistance and changeable
degrees of masculinization. Irreversible fertility often results from the severe
deficiency or lack of sperm caused by this disorder.

anemia
: A condition in which the blood is
deficient in red blood cells, in hemoglobin, or in total volume.
|
|
Angiomyolipoma
- Also known as renal hamartoma, angiomyolipomas are rare benign tumors
usually caused an inherited genetic mutation. They can occur on an isolated,
individual basis, but most often are associated with the rare genetic disease
called tuberous sclerosis, an affliction characterized by small tumors of the
blood vessels, resulting in numerous bumps on the skin, mental retardation,
seizures, cysts in the kidneys, liver and pancreas, and, in some cases, RCC.
About 80% of persons diagnosed with tuberous sclerosis also have hamartoma.
In patients without tuberous sclerosis, hamartoma most often occurs in
middle-aged women. Most cases are discovered when the patient undergoes a CT
scan for an unrelated abdominal problem, complains of gastrointestinal
discomfort, or suffers a sudden hemorrhage caused by the rupture of a large
tumor.
Management of the condition depends on the size of the tumors and the
severity of the symptoms they produce. Asymptomatic patients and those with
small tumors usually are not treated; instead, they are observed periodically
with an eye toward surgery if the tumors grow or produce symptoms. Because of
the potential for spontaneous rupture and life-threatening hemorrhage, patients
with large tumors usually are considered candidates for some form of surgical
treatment, ranging from partial nephrectomy to arterial embolization.
|
|
Antibiotics
-
Antibiotics frequently are prescribed to eliminate infections that could impair
fertility, such as infections of the urinary tract and prostate. The physician
will be especially inclined to prescribe an antibiotic if leukocytes (white
blood cells) are detected in the man's semen sample. Strong antibiotic
medications - like double- strength trimethoprim plus sulfamethoxazole (Bactrim
DS) and doxycycline hyclate (Vibramycin) - often are the drugs of choice. They
usually are administered for intervals of 1 to 3 months. Nitrofuran antibiotics
are avoided, since they may impair sperm maturation. STDs, such as gonorrhea or ureaplasma, commonly are treated with ceftriaxone sodium or doxycycline.

anxiety:
A debilitating condition of fear,
which interferes with normal life functions.
|
|
Arterial
Embolization
- This procedure usually is reserved for patients
whose overall health does not permit surgery, such as those with heart or lung
problems. In arterial embolization, a very small tube called a catheter is
inserted through a blood vessel in the groin and passed up to the kidney. There
it is used to inject a small piece of gelatin sponge into the artery that
supplies blood to the cancerous kidney. This cuts off the flow of blood to the
kidney and the cancerous tumor, which die. The kidney usually is surgically
removed at a later date, if and when the patient's overall condition permits.
|
|
Artificial
Insemination
- Artificial insemination (AI) is a process in which a
relatively large number of healthy sperm are deposited in a woman by artificial
means. The sperm are placed either at the entrance to the cervix or directly
into the uterus (womb) near the fallopian tubes (intrauterine insemination or IUI). Artificial insemination is particularly useful when the male partner's
sperm count is low or when sperm quality is below average (e.g., in cases of
spinal cord injury, ejaculation disorder or impotence). The sperm can be
prepared by washing, concentration, or other methods to ensure the best chance
of conception (see also Sperm Retrieval). Artificial insemination also is
commonly performed using sperm from a donor.
|
|
Artificial Sphincter
-
Sometimes complicated cases of incontinence require implantation of a device
known as an artificial urinary sphincter. People who might benefit from this
treatment include those who are incontinent after surgery for
prostate cancer or stress incontinence, trauma victims and people with
congenital (present at birth) defects in the urinary system.
The artificial sphincter has three components, including a pump, balloon
reservoir, and a cuff that encircles the urethra and prevents urine from leaking
out. The cuff is connected to the pump, which is surgically implanted in the
scrotum (in men) or labia (in women). The pump can be activated (usually by
squeezing or pressing a button) to deflate the cuff and permit the bladder to
empty. After a brief interval, the cuff refills itself and the urethra is again
pressed closed.
Because the artificial sphincter is an implant, it is subject to the risks
common to implants, such as infection, erosion (breaking down of tissue) and
mechanical malfunction. Yet with appropriate presurgical evaluation, operative
techniques and postoperative follow-up, many problems can be avoided and
incontinent patients can experience an improved quality of life with this
device.

assisted reproductive
technologies (ART) : The new forms of fertility treatment incorporate
many methods of sperm retrieval and preparation. Once the sperm have been
processed to ensure optimal fertilizing potential, they are used in a variety of
procedures that aid the process of conception. These procedures include
artificial insemination (AI), in vitro fertilization (IVF), and sperm
microinjection techniques.

AUA (American Urological Association) Score
- The AUA Score or Symptom
Index is a self-administered questionnaire used to establish how severe a
patient's BPH symptoms may be. It asks seven questions related to common
symptoms of BPH and asks the patient to rate the degree of frequency or severity
for each on a scale of 1 to 5. A total AUA Score of 0 to 7 is considered mild; 8
to 19 is rated moderate, and 20 to 35, severe.

Augmentation makes the bladder larger, most
often by adding a section of the patient's small intestine, a tube-like
structure that absorbs and transports nutrients from food for use by the body.
With this treatment, scarred, ulcerated and inflamed sections of the patient's
bladder are removed, leaving only healthy tissue and the base of the bladder. A
piece of the patient's small intestine is removed, reshaped, and attached to
what remains of the bladder. After the incisions heal, the patient may be able
to void normally.
Even in carefully selected patients-those with small, contracted bladders-the
pain, frequency, and urgency may remain or return after surgery and the patient
may have additional problems with infections in the new bladder and difficulty
absorbing nutrients from the shortened intestine. Some patients are incontinent
while others cannot void at all and must insert a catheter into the urethra to
empty urine from the bladder.

BALLOON DILATION
- Balloon dilation has
been used clinically as an alternative to prostatectomy. It is very similar to
the angioplasties done for coronary artery disease. Basically, a balloon is
placed into the prostatic channel, either by finger guidance or telescopic
guidance, and the balloon is then inflated to stretch the prostate channel. This
has the apparent end result of tearing the prostate gland and creating a wider
opening in the urinary channel. No prostate tissue is removed and the procedure
does not work well for very large prostates. Recent numerous studies have
demonstrated that most of the patients after balloon dilation have recurrence of
their symptoms relatively soon and require repeat treatments within two years.
With today's wider and more efficaceous variety of BPH treatments, balloons are
less accepted as a viable alternative treatment.

Biofeedback/Electrical
Stimulation
- Biofeedback is practiced to help people gain awareness and
control of their urinary tract muscles. The principle of biofeedback is simple:
a variety of instruments are used to record small electrical signals that are
given off when specific muscles are squeezed during contraction. These
contraction-related signals are instantly converted into audio and/or visual
signs that patients can recognize and learn from, in order to control muscular
activity. With biofeeback, weak muscles can be better activated on demand,
overly tense muscles can be relaxed, and overall muscle activity can be
coordinated.
Biofeedback usually is performed in conjunction with Kegel exercises, since
it helps to reinforce correct Kegel techniques. Biofeedback lets patients
visualize and identify the pelvic floor and/or abdominal muscles that are
appropriate for their exercise programs.
Neuromuscular electrical stimulation (NMES) also is employed to "reeducate"
and strengthen weak urinary muscles. In NMES, electrical stimulation of the
pudendal nerve causes contraction of the pelvic floor and periurethral
(urethra-encircling) muscles. A probe is inserted into either the vagina (female
reproductive canal) or anus (outside opening of the large intestine), and NMES
is applied at an intensity that is below the threshold of pain. Most NMES
devices are biphasic: that is, they produce a current that stimulates
contraction, followed by a rest period of 5 to 10 seconds.
Patients are instructed to join in with the NMES-stimulated contraction. Such
assisted exercise eventually strengthens the pelvic floor muscles and improves
bladder control. Electrical stimulation can be used to reduce both
stress incontinence and
urge incontinence. NMES treatment programs usually last 20 to 30 minutes.
NMES devices are available for both home and hospital use.

Bladder Augmentation -
Individuals who suffer from a low-capacity bladder -- for example, a bladder
that is small, hyperactive or nonresilient -- may benefit from surgery that
increases the fluid-holding potential of the bladder. Surgery that increases
bladder capacity, otherwise known as bladder augmentation or augmentation cystoplasty, is conducted using either the bladder itself (autoaugmentation) or
bowel (intestine) segments. Such surgery is not recommended for patients who are
unable to perform self-catheterization (self-placement of a urinary tube) or who
have kidney disorders, bowel disease or urethral disease.
Autoaugmentation is a novel method of bladder augmentation. It increases the
capacity of the bladder without using bowel or stomach segments, which may
result in complications after other augmentation procedures. During autoaugmentation, the detrusor (the smooth muscle in the wall of the bladder
that contracts and expels urine) is cut out of the dome of the bladder, leaving
the mucosa (mucous membrane tissue) intact. This procedure creates a bladder
with reduced muscle squeezing ability and improved function; however, long-term
findings in some subjects suggest that contraction of the mucosa eventually can
occur.
Bowel augmentation makes use of segments from the ileum (the last part of the
small intestine), cecum (the first part of the large intestine) or ileocecum
(junction between the small and large intestines) to increase the capacity of
the bladder. In all bowel augmentation procedures, the bowel segments are
changed in shape from a cylinder to a sphere to produce a flexible, low-pressure
vessel. The bladder is opened at the dome and is cut at right angles on each
side to create a clam-like shape. The open bowel segment then is joined to the
"clammed" bladder with sutures.
Bowel augmentation is associated with post-operative complications, such as
leakage of urine, continued incontinence, and kidney problems. Long-term risk
factors include the development of bladder stones, increased risk of bladder
cancer and increased risk of incontinence during and after pregnancy.

Bladder Cancer -

|
|
Bladder Distension - Because some
patients have noted an improvement in symptoms after a bladder distension done
to diagnose IC, the procedure is often thought of as one of the first treatment
attempts.
Researchers are not sure why distension helps, but some believe that the
procedure may increase bladder capacity and interfere with pain signals
transmitted by nerves in the bladder. Symptoms may temporarily worsen 24 to 48
hours after distension, but should then return to predistension levels or
improve after 2 to 4 weeks.
|
|
Bladder Instillation
- This
procedure may also be called a bladder wash or bath. During a bladder
instillation, the bladder is filled with a solution that is held for varying
periods of time, from a few seconds to 15 minutes, before being drained through
a narrow tube called a catheter.
The only drug approved by the U.S. Food and Drug Administration (FDA) for
bladder instillation is dimethyl sulfoxide (DMSO, RIMSO-50). With DMSO
treatments a narrow tube (catheter) is guided up the urethra into the bladder. A
measured amount of DMSO is passed through the catheter into the bladder, where
it is retained for about 15 minutes before being expelled. Treatments are given
every week or two for 6 to 8 weeks, and repeated as needed. Most people with IC
who respond to DMSO notice improvement of symptoms 3 or 4 weeks after the first
6- to 8-week cycle of treatments. Highly motivated patients who are willing to
catheterize themselves may, after consultation with their doctor, be able to
have DMSO treatments at home. Self-administration of DMSO is less expensive and
more convenient than going to the doctor's office.
Doctors think DMSO works in several ways. Because it passes into the bladder
wall, DMSO may more effectively reach tissue to reduce inflammation and block
pain. It may also prevent muscle contractions that may cause pain, frequency,
and urgency.
A bothersome but relatively insignificant side effect of DMSO treatments is a
garlic-like taste and odor from the breath and skin. This may last up to 72
hours after a treatment. Long-term DMSO treatments have caused cataracts in
animal studies, but this side effect has not appeared in humans. Blood tests,
including a complete blood count and kidney and liver function tests, should be
done about every 6 months.
A variety of other drugs have been used experimentally for bladder washes,
including silver nitrate, sodium oxychlorosene (Clorpactin WCS-90), heparin, and
pentosanpolysulfate (Elmiron).
Silver nitrate and oxychlorosene sodium are thought to work by first
attacking the bladder lining. This triggers the body's immune system to step in
and start the healing process. Some patients have been successfully treated with
these drugs, but the frequent, painful treatments usually must be done under
general anesthesia. Neither drug can be used in people who have urinary reflux,
a condition in which urine flows backward up the ureters into the kidneys.
Heparin and pentosanpolysulfate are thought to work by replacing or repairing
the "leaky" bladder lining.
|
|
Bladder Removal (Cystectomy)
- Different methods can be used to reroute urine once the bladder has been
removed. In most cases, the ureters are attached to a piece of bowel that opens
onto the skin of the abdomen, called a stoma. Urine empties through the stoma
into a bag outside the body. This procedure is called a urostomy. Some
urologists are using a technique that also requires a stoma but allows urine to
be stored in a pouch inside the abdomen. At intervals throughout the day, the
patient puts a catheter into the stoma and empties the pouch. Patients with
either type of urostomy must use very clean, or sterile, steps to prevent
infections in and around the stoma.
With a third method, a new bladder is made from a piece of the patient's
bowel (large intestine) and attached to the urethra in place of the removed
bladder. After a time of healing, the patient may be able to empty the bladder
by voiding at scheduled times or may insert a catheter into the urethra. Few
surgeons have the special training and expertise needed to perform this
procedure.
Even after total bladder removal, some patients still experience variable
symptoms of IC. Therefore, the decision to undergo a cystectomy should only be
undertaken after serious deliberation on the potential outcome.

Bladder Stones -

Bladder Training - People who have
found some relief from pain may be able to reduce frequency using bladder
training techniques. Methods vary, but basically the patient decides to void at
designated times and use relaxation techniques and distractions to help keep to
the schedule. Gradually, the patient tries to lengthen the time between the
scheduled voids. A diary of voids is usually helpful in keeping track of
progress.

Blood Tests
- Another laboratory
procedure typically used in the diagnosis of RCC involves microscopic and/or
chemical examination of the patient's blood to detect conditions that indicate
the presence of cancer. These tests screen for:

|
Bone Scan - This is another nuclear
imaging procedure used to detect the spread of cancer to bones. It usually is
prescribed in cases where aggressive tumors and metastasis are suspected. In a
bone scan, a small amount of low-level radioactive material is injected into the
body. This material discloses metastatic cancer, as well as some noncancerous
diseases, in bones.
|
|
Brachytherapy
- Technically,
brachytherapy is more a form of therapy than a surgical procedure, but it does
involves a surgical element - the implantation of tiny, radioactive implants
into a cancerous prostate gland. Radiation emitted by the implants kills the
malignant tumor. Men whose cancers are small and confined to the prostate (Stage
1 or 2) are candidates for brachytherapy.
The physician first uses an ultrasound device (TRUS) to create a
three-dimensional grid map of the prostate. A computer then is used to calculate
the volume of the gland, the number of radioactive implants (called "seeds")
that will be needed and where they should be placed.
The procedure, performed on an outpatient basis, takes 45 to 60 minutes and
is done under local (spinal) anesthesia. From 50 to 100 rice-sized seeds are
then inserted by a special needle through the perineum and into the prostate in
a preplanned pattern, guided by the TRUS and grid map. The seeds contain a
radioactive isotope, usually Palladium 103 or Iodine 125, which emit radiation
for about three months before decaying to an inert state.
Brachytherapy patients can be discharged the same day and usually resume
normal activity within a day or two. A small proportion, generally those over
70, experience incontinence or impotence problems. But brachytherapy has been
found to deliver a higher and better focused dose of radiation with fewer side
effects and at substantially lower cost than external beam therapy. In a recent
study of 111 brachytherapy patients, 100% were prostate cancer free after five
years.

Bromocriptine
- Bromocriptine is a drug that is classified as a dopamine agonist. This means
that bromocriptine acts like dopamine, a catecholamine (sympathetic nervous
system chemical) that stops the release of prolactin hormone from the pituitary
gland. Bromocriptine therapy is useful for men in whom impaired sperm production
is due to hyperprolactinemia (high blood level of prolactin) (see also
Hyperprolactinemia).The customary daily dose of bromocriptine is 5-10 mg. The
side effects of bromocriptine therapy include high blood pressure, headache,
dizziness, nausea, and vomiting.
|
|
BTA test
-The BTA® test was designed to detect
proteins that are released by reproduction of bladder tumor cells, and its
interpretation does not require a technician or specialist. The BTA® test
significantly identifies superficial (surface) bladder tumors by changing color.
The top of the BTA® test strip turns yellow when positive for bladder cancer,
and it turns green when negative. The BTA stat test is an immunologic assay that
can be used to identify recurrent bladder cancer. The FDP® test detects the
breakdown products of blood-clotting proteins (fibrin, fibrinogen), which are
increased in the urine in the presence of bladder cancer. Both the BTA stat and FDP® tests are superior to voided urine cytology, especially for low-stage and
low-grade disease.

Burch
procedure, also known as Burch
colposuspension (vaginal suspension), often is performed when the abdomen is
already open for another purpose, such as abdominal hysterectomy. During the
suspension procedure, the sutures are placed laterally (sideways), which avoids
urethral obstruction and allows the physician to repair any small cystoceles
that may be present. The bladder neck and urethra are separated from the back
surface of the pubic bone. The bladder neck then is elevated by means of lateral
sutures that pass through the vagina and Cooper's (pubic) ligaments. The vaginal
wall and ligaments are brought together without tension, and the sutures are
tied.

Calcium Stones
- About 70% to
80% of all kidney stones are composed of hard crystals of either calcium oxalate
or insoluble phosphate salt, or a combination of both. Calcium stones are the
most common type experienced by people of Anglo-Saxon descent. They occur in
people who have hypercalciuria, a condition characterized by excessive calcium
in the urine. Calcium is a normal part of a well-balanced diet, responsible for
maintaining the health of teeth and bones. In most people, excess calcium is
flushed out by the kidneys and excreted in the urine. People with hypercalciuria
build up excess calcium in their kidneys, where it joins with other waste
products to form a stone.
In about 40% of people who develop calcium stones, this buildup is caused by
an inherited metabolic disorder whose cause is unknown. In rare cases, a tumor
on the parathyroid gland may trigger an overproduction of parathyroid hormone,
the chemical that regulates calcium metabolism. Certain drugs, such as the
diuretic furosemide, antacids and steroids, can produce hypercalciuria. It also
can be brought on by certain intestinal diseases, excessive amounts of vitamin A
or D, or a diet too high in purine, typically associated with meat, fish and
poultry consumption.
Calcium oxalate stones also are commonly associated with having too little
vitamin B or too much vitamin C in one's diet.

can be dissolved with the application chemicals. Uric acid stones, for example,
can be dissolved with a solution of sodium bicarbonate in saline. Cystine stones
may be treated successfully with a combination of acetylcysteine and sodium
bicarbonate in saline. Struvite and carbon apatite stones can be treated with an
acidic solution of hemiacidrin. The procedure involves infusing the chemical
solution into the affected area by means of a ureteral catheter in a series of
treatments over time until the stone is dissolved. The patient's urine must be
cultured regularly throughout the course of treatment to guard against urinary
infection and prevent the buildup of excessive chemical levels, particularly
magnesium, which can cause other health problems.

Clomiphene Citrat
e
- Clomiphene citrate, a synthetic steroid drug related to estrogen (female sex
hormone), has both anti-estrogenic and estrogenic effects. In men with
oligospermia (low sperm count), clomiphene has been used to increase
gonadotropin secretion, which, in turn, may stimulate testosterone release and
improve sperm output (see also Endocrine Disorders). Yet the male response to
the drug is not as pronounced as that seen in women. Clomiphene usually is given
in oral daily doses of 25-50 mg for a 3- to 6-month period. However, the results
from clomiphene trials are extremely variable, with differing success rates for
conception. Therefore, more clinical data are needed to confirm the
effectiveness of this drug.

Combined Estrogen/Alpha-Adrenergic Agonist Therapy
- Since estrogen therapy
appears to heighten the response of nerve receptors in the urethra (that is, the alpha-adrenergic receptors, which increase the tone of striated and smooth
muscle), it is believed that a combination of estrogen and alpha-adrenergic
agonists (drugs specific for the alpha-adrenergic receptors) may be beneficial
in women who have undergone menopause and who lose bladder control because of
insufficiency (malfunction) of the urinary sphincter muscles.
A common estrogen/alpha-adrenergic agonist combination is phenylpropanolamine (PPA, 25-100 mg twice a day) plus intravaginal or oral conjugated estrogen (1.25
mg/day orally or 2 g/day vaginally). Phenylpropanolamine is found in many
over-the-counter cough/cold preparations, such as Tavist-D, Comtrex, Dimetapp,
Triaminic, and Robitussin-CF.

Computed Tomographic (CT)
Scan
- Also known as a computer-assisted tomography or "CAT" scan,
the CT scan is a type of X-ray procedure that gives three-dimensional images of
internal organs or glands. It can be used to detect pelvic lymph nodes enlarged
by cancer, although some authorities suggest its results are insufficient for a
clear diagnosis. CT scans typically are used only when tumors are large or
associated with high PSA levels.

Congenital adrenal hyperplasia (CAH)
- An uncommon inherited
disorder that may be associated with a lack of 21-hydroxylase - an enzyme found
in the adrenals (glands above each kidney). Hyperplasia (overgrowth) of the
adrenals leads to excessive production of adrenal testosterone that, in turn,
inhibits the release of pituitary gonadotropin.
Early puberty and short stature (height) are hallmarks of CAH. However,
congenital adrenal hyperplasia is difficult to diagnose, since affected men
often appear "normal" and sexually mature, without excessive masculinization.
Men with CAH often will show low/normal blood levels of adrenal steroid
compounds, such as cortisol. In addition, they may have low/normal urinary
levels of 17-hydroxycorticoid and high urinary levels of 17-ketosteroids and
pregnanetriol (a byproduct of the pregnancy hormone progesterone). Testicular
tumors sometimes are detected in men with CAH (see also Testicular Tumors).
Dexamethasone may be used to suppress adrenal secretion in men with CAH. In
addition, glucocorticoid therapy may provide fertility benefits in men with CAH
by increasing sperm output.

alternative uses a TRUS-guided probe to deliver freezing temperatures to the
cancerous tumor. Intermittent freezing and thawing kills the cancer cells.
Long-term results of cryosurgery are still unknown. Reported side effects
include urinary incontinence, rectal injury and impotence.

Cryptorchidism - Cryptorchidism, also known as cryptorchism, is the failure of one or
both testes to descend (move down) into the scrotum. The descent usually is
complete at birth or by the end of the first year of life. However, if the
testes do not drop and remain in an upper, abdominal location, spermatogenesis
(sperm production) and, correspondingly, fertility, usually is impaired.
Unilateral (one-sided) cryptorchidism is associated with oligospermia (low sperm
count), whereas uncorrected, bilateral (two-sided) cryptorchidism usually is
associated with azoospermia (no sperm in the semen). Researchers believe that
the increased temperature within the abdomen harms the enzymes and proteins that
are responsible for normal sperm production. Sperm quality may be especially
poor in men who have bilateral undescended testes.

Culture of Prostate Secretions
- In men, the doctor will obtain prostatic fluid from the patient. This fluid
will be examined for signs of an infection, which can be treated with
antibiotics.

cyst
: A lump filled with either fluid or soft
material, occurring in any organ or tissue; may occur for a number of reasons
but is usually harmless unless its presence disrupts organ or tissue function.
|

cystectomy
: Surgical removal of the bladder.
|
|
Cystic Fibrosis
- Low
ejaculate volume and azoospermia (lack of sperm in the semen) are common
findings among men who carry a gene for cystic fibrosis. This is because male
cystic fibrosis patients usually have an inherited, bilateral absence of the vas
deferens and malformations or absence of seminal vesicles.
|
|
Cystine Stones
- Cystine is one
of the body's chemical building blocks, an amino acid that helps make up nerves,
muscles and other body tissues. A rare genetic defect called cystinuria can
cause excessive cystine buildup in the urine, leading to the development of
cystine stones in the kidneys. Cystine stones are relatively rare, occurring in
about 1% to 2% of persons who experience kidney stone disease. Because it is
genetically inherited, the condition often runs in families.

Cystometrogram
- The
cystometrogram is the most important of the urodynamic tests. It is used to
examine the different phases of bladder function, such as filling and voiding.
During cystometry, the intra-abdominal pressure (pressure within the pelvic
cavity) and the detrusor pressure (downward-pushing pressure of the bladder) are
electronically recorded and subtracted.
In tests of filling cystometry, the bladder is filled to capacity, then
tested for volume, sensation, involuntary instability (contraction, or muscle
squeezing) and compliance (yielding to pressure). Any change in detrusor
pressure may indicate an abnormality, especially if it mimics the patient's
symptoms, such as urgency and increased frequency of urination. The patient is
asked to cough and strain with a full bladder. Urine leakage without a change in
detrusor pressure may indicate a diagnosis of
stress incontinence. By contrast, patients with
urge incontinence may experience detrusor contractions, with urine leak
during filling and a related sensation of urgency.
Voiding cystometry tests usually are normal in patients with
stress incontinence,
urge incontinence, and
mixed incontinence. However, patients with intrinsic sphincter deficiency
may lose urine without any indication of detrusor contraction. In addition,
patients with an acontractile (noncontracting, nonsqueezing) bladder -- for
example, patients with diabetes, spinal cord injury or prior pelvic surgery --
will have a low detrusor pressure during voiding and a pattern of straining.
|
|
Cystoscopy
- Cystoscopy, or cystourethroscopy, is a test that lets the physician see the inside of the
bladder, bladder neck and urethra. A cystoscope (a thin, telescope-like tube
with a tiny attached camera) is inserted into the bladder through the urethra.
The physician then moves the cystoscope to detect any abnormalities in the
urinary tract, such as trabeculation (strands of connective tissue), diverticula
(sacs caused by abnormal holes in the organ), fistula (abnormal passages), an
ectopic (displaced) ureter, ureterocele (ballooning of the lower end of the ureter), tumor, or changes in the lining of the urinary tract.

Denervation
is a complicated procedure done
by surgeons who have special training and expertise. Rarely used in the
treatment of IC, it involves cutting some of the nerves to the bladder,
interfering with pain signals. Many approaches and techniques are used, each of
which has its own advantages and complications that should be discussed with the
surgeon.
Depending on your diagnosis your physician may elect to use a sling made of
either a biocompatible synthetic material or of your own tissue. This sling
(like a hammock) is secured to the anchor placed in the bone and serves as
additional support for the urethra, bladder neck and sphincter.
detrusor-external
sphincter dyssynergia (DESD)
: Damage
to the nervous system can create a lack of coordination between the bladder and
the external sphincter muscle, which is the muscle that controls the emptying of
the bladder. As a result the bladder cannot empty completely which creates a
buildup of urinary pressure. DESD is a combination of thses two factors and can
lead to severe urinary tract damage and life-threatening consequences.

|
diabetes mellitus
:
A common form of diabetes in which the body cannot properly store or use glucose
(sugar), the body's main source of energy.
|
|
Diet
- There is no scientific evidence linking diet
to IC, but some doctors and patients believe that alcohol, tomatoes, spices,
chocolate, caffeinated and citrus beverages, and high-acid foods may contribute
to bladder irritation and inflammation. Some patients also notice a worsening of
symptoms after eating or drinking products containing artificial sweeteners.
Patients may try eliminating such products from their diet and reintroduce them
one at a time to determine which, if any, affect symptoms. It is important,
however, to maintain a well-balanced and varied diet.
|
|
Digital Rectal Exam (DRE)
- In a DRE, the physician inserts a lubricated, gloved finger into the
patient's rectum to feel the surface of the prostate gland. Healthy prostate
tissue is soft, like the fleshy tissue of the hand where the thumb joins the
palm. Malignant tissue is firm, hard, often asymmetrical or stony, like the
bridge of the nose. The test is subjective, however, and relies on the
physician's ability to interpret what he or she feels. Only larger tumors can be
felt; as many as one-third of patients subsequently diagnosed with prostate
cancer actually will still have a normal DRE.

Ditropan® XL
- Extended-release
tablets contain oxybutynin chloride. Ditropan® XL is a once-a-day medication for
overactive bladder. One tablet releases medication into your system continuously
for relief that lasts up to 24 hours with one dose. In many patients, once-a-day Ditropan® XL has been shown to help effectively treat urgency, frequency, and
wetting accidents. Some patients use far fewer pads. Some patients experienced
relief after taking Ditropan® XL after 1 week. In a clinical study with Ditropan® XL, patients experienced a 90% reduction (from 16 to 2) in the number
of wetting accidents per week versus patients taking a sugar pill who
experienced a 51% reduction (from 21 to 11). The typical dosage is 5-15 mg to be
taken orally 1 time/day. In clinical studies, the most common side effect was
dry mouth. However, only 1% of patients discontinued therapy for this reason.
Other common side effects included constipation, drowsiness, diarrhea, blurred
vision, dry eyes, dizziness, and runny nose. Only 7% of patients in clinical
studies discontinued therapy due to side effects.

Dormia basket
is, as the name
implies, a small basket made of thin metal wire. Especially smaller stones, that
are located in the 'lower' ureter can be reached through urethra and bladder,
picked up in the basket and pulled out. General anesthesia is necessary, because
such a treatment can be quite painful. It is an easy an quick method, although
sometimes the stones do not get 'grabbed' by the basket.
|
|
Doxazosin mesylate (Cardura)
- Doxazosin mesylate is a drug that acts by blocking the alpha-1 adrenergic r
receptor sites within the body. Doxazosin is prescribed for the treatment of
urinary outflow obstruction in BPH and for hypertension. The typical dose is 1-8
mg, taken once daily.
|
|
Duct Obstruction
- If a man is found to have normal levels of reproductive hormones and a
normal testis biopsy, yet his semen does not contain sperm and it is
fructose-negative, then the physician should consider the possibility of
ejaculatory duct obstruction due to inherent or inflammatory causes.
Repeated urinary tract infections (UTIs) - as experienced by men with spinal
cord injuries - may lead to inflammation of the prostate or epididymis which, in
turn, may lead to ductal obstruction. In addition, vasectomy - a contraceptive
procedure in which the vas deferens is cut - is now the leading cause of
infertility due to ductal obstruction in men who have undergone vasectomy
reversal procedures.

Electrical Stimulation
- Electrical stimulation of the sacral autonomic and somatic nerves has
been used with varying degrees of success to treat stress and urge urinary
incontinence as well as urgency and frequency syndromes. Most of the studies
documenting use of the technology have been uncontrolled. Stimulation with
electric current causes initial contraction of the bladder that is followed by a
prolonged relaxation and gradual fatigue of the contractile response. In
addition, stimulation results in reflex inhibition that may "calm" the detrusor
and improve storage; however, the ultimate role of this treatment modality is
not yet known.
|
|
ELECTROEJACULATION
- Electroejaculation - ejaculation that is stimulated by an electrode -
is a successful form of therapy for men who have normal testes but who cannot
emit semen or ejaculate because of a fault in the sympathetic nervous system.
Candidates for electroejaculation include men who have undergone orchiectomy
(testis removal), retroperitoneal lymph node dissection (RPLND) or spinal cord
injury (see also Neurogenic Causes).
The technique of electroejaculation involves the placement of a probe in the
rectum (end of the large intestine). Electrical current from the probe then
causes the emission of semen due to direct stimulation of nerve fibers within
the male reproductive tract. Forceful ejaculation generally does not occur
during this procedure, and semen may be released in an antegrade/retrograde
manner - that is, semen may dribble out through the urethra, or it may be
released backward into the bladder (see also Retrograde Ejaculation). Because
semen may need to be retrieved from the urine, the urine will be made alkaline (nonacidic)
by having the patient take sodium bicarbonate tablets (600 mg) during the day
before the procedure.
|
|
electrohydraulic lithotripsy (EHL)
:This
technique uses a special probe to break up small stones with shock waves
generated by electricity. Through a flexible ureteroscope, the physician
positions the tip of the probe 1 mm from the stone. Then, by means of a foot
switch, the physician projects electrically generated hydraulic shock waves
through an irrigating fluid at the stone until it is broken into small
fragments. These can be passed by the patient or removed through the previously
described extraction methods. EHL has some limitations: It requires general
anesthesia, and is generally not used in close proximity to the kidney itself,
as the shock waves can cause tissue damage. Fragments produced by the hydraulic
shock also tend to scatter widely, making retrieval or extraction more
difficult.

Electromyography (EMG) - Electromyography, or EMG, is used to evaluate the electrical activity
of urinary tract muscles in patients who are suspected of having nerve disorders
(multiple sclerosis, spinal cord injuries, lesions, or disease) or functional
incontinence. EMG also can be used for biofeedback and medicolegal
(medical/legal) cases.
The patient is placed in a comfortable, supine (lying with the face upward)
position, with extended legs. Needle electrodes are placed in test muscles (for
example, the bulbocavernosus [urethra-tightening] muscle in men), surface
electrodes are placed on the skin (for example, the vaginal lining in women),
and catheter electrodes are mounted on a catheter that is placed in the urethra.
These electrodes detect electrical activity in the urinary tract muscles when
the patient is told to hold urine. Patients with neurologic (nervous system)
disorders may show dyssynergia (incoordination) between the detrusor and
sphincter muscles, involuntary muscle spasms, or detrusor instability (unstable
bladder).

external beam radiation therapy
:
A 25-28 treatment protocol that utilizes External Beam Radiation. Approximately
6800-7400 rads of radiation energy is delivered to the Prostate. There can be
some radiation effect on surrounding tissues.
|
|
External Radiation Treatment (XRT)
- This, too, is more a
form of therapy than surgery. It usually is prescribed for patients with
localized cancer, that is, those whose tumors have spread outside the prostate
capsule, but are still likely confined to the immediate surrounding tissues.
Treatment involves projecting a high-energy beam of X-rays onto the prostate
tissues from a machine outside the body. The radiation kills cancer cells and
shrinks tumors. Radiation treatment usually is done on an outpatient basis over
a period of 7 to 8 weeks. Common side effects include impotence, particularly in
older men, discomfort with urination, urinary urgency and diarrhea, especially
during the later stages of treatment.

Fibroma
- Fibromas are tumors of the
fibrous tissue on, in or surrounding the kidney. They are rare and most often
found in women. Their cause is unknown. Usually they grow on the periphery of
the kidney and can become large before becoming clinically obvious. Most are asymptomatic. While generally benign, these tumors have no special
characteristics to differentiate them from other, malignant tumors of the
kidney. Because of this uncertainty of diagnosis, most physicians treat them
surgically. Partial or radical nephrectomy is the standard approach.
|
|
Fine Needle Aspiration
- As noted, the tumors that
characterize RCC are made up of malignant (cancerous) cells that grow together
in a mass. If imaging or other procedures detect the presence of a tumor, a cell
sample may be taken for microscopic examination.
In general, physicians avoid performing needle biopsies of suspected kidney
tumors because of the risk of causing bleeding or other complications. However,
in some cases the tumor may contain a fluid-filled cyst. By puncturing the cyst
with a fine needle, a small amount of this fluid can be drawn out for
examination by a pathologist, who will look for cancer cells. This can help
determine the type of cancer a patient has, and aid the physician in
recommending an appropriate form of treatment. While no longer common, a similar
technique can be employed to collect a sample of solid tissue from a noncystic
tumor.

Gamete Intrafallopian Transfer - Gamete
intrafallopian transfer (GIFT) is an ART procedure in which the egg and sperm
(gametes) are placed together within the fallopian tubes. Like IVF, GIFT
requires prior, hormone-induced "super stimulation" of the woman's ovaries to
produce mature eggs. The eggs then are retrieved from the woman by laparotomy, a
surgical incision through the abdomen. After a number of mature eggs have been
collected, they are combined with sperm which, as in IVF, has been treated to
concentrate the most healthy and active cells. Finally, the gametes are
transferred back into the fallopian tubes, where fertilization should take
place. Any embryos that result from this procedure will naturally descend into
the uterus for implantation.
Gittes procedure is a transvaginal technique that does not require an
incision. Instead, a small puncture is made above the pubic fat pad. A suture is
then transferred by a needle through the rectus (muscle of the pubic crest) and
down toward the vaginal wall, where it is looped and drawn back and out through
the puncture. A second pass is made through the same incision (1 or 2 cm beside
the first pass) to create a strong support for the suspension. The process is
repeated through another puncture hole, which is made 1.5 to 2.0 cm away from
the first site. Both suspending sutures are tied down within their respective
puncture sites.
Bone anchors are new additions to the techniques for needle suspension of the
bladder neck. When needle suspension was first developed, surgeons questioned
the amount of tension that was suitable for the suspension sutures. They wanted
to avoid the complications of bladder outlet obstruction and suture breakdown
that could because by too much tension or sutures pulling out of the anchoring
tissue.
|
|
Gleason Score - Once the presence of a cancerous tumor has
been confirmed by biopsy, the pathologist will evaluate its relative malignancy
and potential for metastasizing (spreading). He or she will examine the biopsy sample(s) under a microscope while looking for cells or groups of cells that are
markedly different from healthy tissue. The greater the disparity between the
healthy cells and those that are malignant, the more likely the tumor is
aggressive and will spread. The usual method for expressing the results of this
analysis is the Gleason Grading System.
Under the Gleason System, the pathologist examines biopsy samples from two
different parts of the tumor and assigns them a grade of 1 to 5 based on their
degree of differentiation (the amount by which they differ from healthy tissue).
The more abnormal the tissue, the higher the score. The results of these two
samples are added together to produce a Gleason Score of from 2 to 10. Gleason
Scores of 2 to 4 are considered well-differentiated, meaning the tissue is not
too different from normal; 5 to 7 are moderately differentiated; 8 to 10 are
poorly differentiated. Higher scores indicate aggressive tumors that are likely
to require aggressive treatment.

Gonadotropins - Gonadotropins are
gonad-stimulating hormones. The gonadotropins human chorionic gonadotropin (HCG), human menopausal gonadotropin (HMG), and their combinations very
successfully treat men with hypogonadotropic hypogonadism (delayed sexual
maturity due to sex hormone deficiency) (see also Hypogonadotropic Hypogonadism). Both HCG and HMG stimulate testosterone synthesis, which, in
turn, improves sperm production and pregnancy rates.
Gonadotropin therapy also has been tested in men with oligospermia (low sperm
count) due to unknown causes. For these men, HCG and/or HMG therapy may or may
not improve fertility. Given the expense of such therapy and potential
difficulty of administration (HMG requires injection), most specialists do not
recommend gonadotropin therapy for oligospermic patients.
|
|
Grading - Doctors often will assess an RCC
by its grade. The grade of a cancer cell is a assessment of its appearance
relative to that of a normal, healthy kidney cell. Grading is done on a scale of
1 to 4, with Grade 1 RCCs having cells that differ little from normal. Such
cells typically spread slowly and have a good prognosis for treatment. At the
opposite end of the scale, a Grade 4 RCC looks extremely different from a normal
kidney cell and indicate an aggressive cancer with poor prognosis.

Hemochromatosis - A disorder of iron
metabolism within the body that may lead to fertility problems. Roughly 80% of
men with hemochromatosis experience testicular dysfunction. Such dysfunction may
be caused by abnormal iron deposition within the testes, liver, pituitary gland
and other organs.
|
|
Hormonal Replacement/Estrogen Therapy - Estrogen therapy helps to
maintain and restore the health of urethral tissues in women who have undergone
menopause (the end of monthly menstrual periods). In particular, estrogen
appears to reduce
stress incontinence and heighten bladder outlet resistance by increasing
blood flow, tone and nerve response in the urethral muscle. Yet the exact
mechanism of estrogen is still unknown.
Studies suggest that estrogen replacement therapy, by oral or vaginal
administration, may benefit patients with
stress incontinence or
mixed incontinence . To prevent an abnormal build-up of the endometrium
(lining of the uterus), estrogen replacement should be given with the pregnancy
hormone progesterone (Premphase).
Medications such as Introl and Suctim pro should only be used if the
patient's uterus is present--that is, only if the patient has not had a
hysterectomy.
Various doses of estrogen and progester one are available. Oral conjugated
estrogen usually is given at doses of 0.3-1.25mg per day, and vaginal estrogen
is given at 0.5-2.0g per day.
In addition, estradiol--the most potent naturally-occurring estrogen in
humans--is available as askin-patch (Alora, Climara, Fempatch, Vivelle,
Estraderm) and as a vaginal ring (Estring). All of the sepreparations release
estrogen slowly.
Estrogen therapy is not recommended for patients with diagnosed or suspected
cancer of the breast, cervixoruterus, or for patients with undiagnosed vaginal
bleeding or blood clotting disorders such as thrombophlebitis (inflammation and
clotting of the veins) or thromboembolism (blood clot).

hydrocele:
A painless swelling of the scrotum, caused by a collection of fluid around the
testicle; commonly occurs in middle-aged men.

Hyoscyamine sulfate (Levbid; Cytospaz) - Hyoscyamine
sulfate, like oxybutynin chloride, is an anticholinergic and antispasmotic drug.
It is prescribed for the treatment of
urge incontinence. Hyoscyamine sulfate is specifically contraindicated
(improper) for patients with obstructive urinary tract disorders (for example,
bladder neck obstruction due to an enlarged prostate) and for those with
glaucoma or ulcerative colitis (severe inflammation of the large intestine). -
The usual dosage of hyoscyamine sulfate is one to two 0.375 mg tablets every 12
hours.
|
|
hypermobility:
A condition characterized in which the pelvic floor muscles can no longer
provide the necessary support to the urethra and bladder neck. As a result, the
bladder neck drops when any downward pressure is applied and causing involuntary
leakage. This condition is the most common cause of stress urinary incontinence.
|
|
hyperplasia:
Excessive growth of normal cells of an organ.
|
|
Hyperprolactinemia or Postpubertal Gonadotropin
Deficiency - Gonadotropin shortage in a sexually mature man usually is
the result of a pituitary tumor, which influences the secretion of the
gonadotropins LH and FSH. A tumor, whether small (microadenoma; less than 10 mm)
or large (macroadenoma; greater than 10 mm), may cause excess secretion of prolactin, a hormone produced by the front of the pituitary. Affected men may
experience a loss of libido (sexual desire), reduced potency, gynecomastia (overdevelopment of the male breasts), galactorrhea (spontaneous milk flow), and
altered sperm production. Also, they may produce particularly small amounts of
ejaculate, due to abnormal function of the Leydig cells (testosterone-producing
cells) within the testes. In addition, pituitary insufficiency can result from
other, less common factors such as pituitary damage from surgery or radiation.
The signs of postpubertal gonadotropin deficiency may arise years before any
other symptoms of pituitary tumor (i.e., headache, changes in the visual field,
or low levels of thyroid and adrenal hormones) . If the pituitary tumor is
long-standing (5 to 10 years), the patient eventually may begin to lose
secondary sex characteristics, and the testes may become small, soft and
atrophied (shrunken). Blood testosterone level will be below normal,
gonadotropin levels will be low/low-normal, and testis biopsy will show a lack
of mature Leydig cells. In addition, men with postpubertal gonadotropism may
have below-normal blood levels of corticosteroids, thyroid-stimulating hormone (TSH), and growth hormone.
Men with suspected tumors should undergo scanning by CT (computerized tomography) or MRI (magnetic resonance imaging), and they should undergo
functional laboratory testing of the anterior pituitary, thyroid and kidney.
Since prolactin release is governed by the catecholamine dopamine, the
dopamine-like medication bromocriptine will reduce prolactin levels and restore
normal gonadal function in men with prolactin-secreting tumors (see also Drug
Therapy). The customary therapeutic dose is 5-10 mg daily.

Ileal Conduit - The ileal conduit is a small urine reservoir that is
surgically created from a small piece of the patient's bowel. During this
procedure, the ureters are attached to one end of the bowel piece; the other end
is brought out onto the surface of the body to make a stoma. The patient then
attaches an external, urine-collecting bag to the stoma. This bag needs to be
worn at all times. Complications of the ileal conduit procedure include bowel
obstruction, urinary tract infection (UTI), blood clots, pneumonia, upper
urinary tract damage, and skin breakdown around the stoma.
|
|
Imaging - The preliminary workup usually is followed by one
or more imaging procedures to obtain a visual picture of the kidney(s) and any
abnormalities that may be causing the patient's symptoms. A variety of modern,
accurate, imaging procedures is available to assist the physician in this
process. Most of these procedures are essentially painless, although a few
require the injection of a special "tracer" material (dye or low-level
radioactive isotope) into the patient's bloodstream.
|
|
In Vitro Fertilization - In vitro
fertilization (IVF) is, by definition, the fertilization of an egg in the
laboratory. Using a variety of hormonal drugs, the woman's ovaries are "super
stimulated" to produce eggs. Then, many mature eggs are gathered from the
ovaries, and they are fertilized in the laboratory using the man's sperm. Two
methods used to collect the eggs. Transvaginal aspiration is an
ultrasound-guided technique in which the eggs are aspirated (drawn out) via the
vagina; this procedure also is known as TV collection. Laparoscopy involves an
incision through the abdomen to extract the eggs.
Once the eggs have been collected, they are placed in a special fluid and are
incubated (kept warm) with a prepared sample of the man's semen. The semen
sample will have been processed to separate out the most active, healthy sperm.
After the eggs are fertilized (roughly 48 hours after collection), they are
replaced inside the woman's uterus.
|
|
Incontinence Questionnaire - Your physician may ask you to
complete a questionnaire about your medical history (medications used,
surgeries, illnesses, allergies, etc.) as well as a questionnaire about your
bladder-related symptoms and quality of life. Such questionnaires may be sent to
you before your office visit, or they may be given to you when you arrive for
your appointment. In either case, your physician will use the information that
you provide to help evaluate your condition.
|
|
Inhibitors - Normally, urine contains chemicals that prevent
or inhibit the formation of crystals. Substances known to act as inhibitors
include pyrophosphate, citrate, magnesium, zinc and macromolecules. Another
prevalent theory holds that some persons do not possess these inhibitors in
sufficient quantity to prevent crystallization, or that their inhibitors somehow
fail to produce the necessary chemical reactions that prevent the formation of
crystals. The formation of such crystals is the first stage in the development
of a kidney stone.
|
|
Injectables - Other alternatives to invasive, stress
incontinence surgery include injectable agents that increase the bulk around the
urethra. These agents compress the urethra near the bladder outlet and can
greatly improve the function of the urethral sphincter muscle. Injectable
materials include collagen (a naturally occurring protein found in skin, bone
and connective tissues), polytetrafluoro-ethylene (PTFE, a synthetic compound
known as Teflon, Polyte for Urethrin) and fat.
In women, injectable agents are a good choice if the patient is older, is not
a good candidate for surgery, and has persistent intrinsic sphincter deficiency
without urethral hypermobility (distinguished by leak point pressures less than
90 cm of water). In men, injectable agents may be beneficial for patients with
intrinsic sphincter deficiency that has lasted longer than one year.
The Contigen Bard implant is a new collagen-based form of injection therapy
for leakage caused by stress incontinence. Contigen uses a highly purified form
of collagen made from cowhide; therefore, all potential Contigen recipients
should receive a skin test 28 days before scheduled injection to determine
whether or not they are allergic to bovine collagen.
The Contigen implant is injected around the top of the urethra using
prefilled syringes. The procedure generally is conducted on an outpatient basis
with a local anesthetic (painkiller). Most patients need one to three Contigen
treatments (up to 28 cc) to achieve bladder control.
Polytetrafluoroethylene (PTFE, a synthetic compound known as Teflon, Polytef
or Urethrin), in the form of a micro polymer paste, can be injected into the
upper urethra. The PTFE particles spur the growth off ibroblasts (fiber-making
cells), which help to fix the PTFE in the urethral tissue and assist in urethral
closure. PTFE is not approved in the United States for treatment of
incontinence, because questions remain regarding the potential for PTFE
particles to migrate to other regions of the body, such as the lungs, brain and
lymph nodes.
Fat injections also have been used to treat intrinsic sphincter deficiency.
Autologous fat (fat from the patient's own body) is gathered by liposuction from
the abdominal wall and is then injected around the urethra. Like collagen and
PTFE injection, fat injection is a simple technique that can take place under
local anesthesia. The results of this procedure appear favorable and
cost-effective, although long-term findings are lacking.

Intermittent Catheterization - Intermittent Catheterization involves
inserting a catheter thru the urethra into to bladder to empty it of urine. Once
the bladder is empty the catheter is removed. Intermittent catheterization
should be performed every 3 to 8 hours or as recommended by your physician.

|
Internal Collection Devices - An internal collection device, such as a
catheter (a hollow plastic tube), may be recommended for certain individuals to
ensure that the bladder is emptied on a regular schedule and does not overfill.
Intermittent catheterization -- the periodic insertion of a catheter into the
urethra, past the sphincter muscle and into the bladder -- is performed at
regular intervals each day (usually every 3 to 6 hours).
These devices are usually used in managing cases of neurogenic and overflow
incontinence.
Catheters used for intermittent catheterization range in size. Catheters
usually are attached to a drainage tube and/or bag. Since intermittent
catheterization completely empties the bladder, wetting accidents can be
avoided.
Intermittent catheterization poses a risk of infection because the catheter
must pass from the external environment to the internal environment of the body.
Therefore, hand washing is required before touching the catheter or drainage
bag. In addition, the catheter should be cleaned after each use.

InterStim continence control therapy:
A therapy used in treating urge incontinence. A device, about the size of a
pacemaker, that is implanted into the sacral nerves of the lower spine, where it
delivers electrical impulses that help regulate bladder function. Click

|
Interstitial Laser Coagulation - This new procedure
uses a device called a cystoscope in the urethra to introduce a special
fiberoptic probe directly into the prostate. The probe focuses a beam of
low-power laser energy to vaporize a controlled amount of obstructing prostate
tissue, resulting in prostate shrinkage and improvement of BPH symptoms. The
process is repeated as needed, and takes about 30 to 60 minutes to perform on an
out-patient basis.
|
|
INTERSTITIAL LASER COAGULATION OF THE PROSTATE (ILC) - Similar to
transurethral needle ablation of the prostate, a thin laser fiber is inserted
into the prostatic adenoma via a tranurethral or transrectal route under
ultrasound guidance. Laser energy is then utilize to induce tissue destruction
by local tissue heating with the laser light energy. Preliminary data on small
series of patients suggest it has potential as a viable minimally invasive
surgical alternative for the treatment of BPH. This device is currently not FDA
approved.
|
|
interstitial laser:
A laser probe is placed within prostatic tissue. Laser energy is then used to
destroy prostatic tissue which makes urination easier.
|
|
Intracytoplasmic Sperm Injection -
Intracytoplasmic sperm injection (ICSI) is an IVF procedure in which a single
healthy sperm is injected directly into the egg. ICSI is especially useful when
the man's sperm count is very low or many sperm are abnormal or immotile (see
also Sperm Retrieval). A tiny injection pipette is used to pass the sperm
through the zona pellucida (outside layer) of the egg into its ooplasm (central
substance). In general, ICSI is performed on several eggs. Once they have been
fertilized, they are replaced inside the woman's uterus after a period of about
48 hours.
|
|
Intravenous Pyelogram (IVP) - The doctor also may prescribe
a procedure called an intravenous pyelogram (IVP), which involves injecting a
special dye containing iodine through a vein in the arm into the bloodstream.
The dye eventually collects in the urinary system, where it helps improve the
contrast for X-rays and gives the doctor a better image of the kidneys, ureters
and bladder. By showing up as white on the dark X-ray film, the IVP can disclose
a tumor or the damage a tumor may have caused the kidney.
In some cases the physician may request an arteriogram or venacavagram -
special X-rays of the blood vessels that supply the kidneys - to check for the
presence of tumors in the connecting arteries and veins.

|
intrinsic sphincter deficiency (ISD):
Weakening of the urethra sphincter muscles. As a result of this weakening the
sphincter does not function normally regardless of the position of the bladder
neck or urethra. This condition is a common cause of stress urinary intinence.
|
|
irritable bladder:
Involuntary contractions of muscles in the bladder, which can cause lack of
control of urination.
|
|
Isolated Gonadotropin Deficiency -
Otherwise known as Kallmann's syndrome, isolated gonadotropin deficiency is a
genetically inherited disorder that affects the function of the hypothalamus
(pituitary-linked organ). The features of Kallmann's syndrome include
microphallus (small-sized penis) and/or cryptorchidism (undescended testes)
during childhood. However, the most notable characteristic of Kallmann's
syndrome is delayed puberty. Other Kallmann's syndrome "clues" are a positive
family history of the disorder, anosmia, and "midline" defects such as hare lip,
cleft palate and facial asymmetry.
|
|
Isolated LH Deficiency - Otherwise known
as fertile eunuch syndrome, isolated LH deficiency is notable for the
"eunuchoid" features that are present in affected men. Such features include a
preadolescent distribution and density of body hair; poor skeletal muscle
development, and non-closed epiphyses (ends of the long bones), resulting in an
unusually long arm span and long lower body segment. LH-deficient individuals
often have large testes, but variable secondary sexual characteristics, with or
without gynecomastia (overdevelopment of the male breasts). Fertile eunuch
syndrome is caused by malfunction of the pituitary gland.

Kegels - The Kegel exercises are one of the most common treatments for
stress urinary incontinence. Exercises to strengthen the pelvic floor muscles
were originally described by Kegel in 1948. Such exercises, which are now known
as Kegel exercises, can be used to regain bladder control, especially if the
levator ani (pelvic floor muscle) and/or sphincter muscles have been weakened by
childbirth or other factors.
To identify these muscles, you can perform a contraction (muscle squeeze) to
stop the flow of urine in midstream. If the urine flow stops, you've located the
correct muscles. The next step is to repeat the exercise frequently throughout
the day. Programs of 10 Kegels (for 30 seconds each) every hour, or twice-daily
Kegels (4 seconds each for 5 minutes) have proven effective. The benefits of
Kegel exercises are not immediate, so you should continue the program for at
least 8 to 12 weeks before expecting to experience any results. After you
identify the muscles, Kegels should not be performed during voiding, since urine
could be retained.
In women, weighted vaginal cones sometimes are used to help patients find the
proper muscles to squeeze during Kegel exercise. When the cone is held in place,
the exercise is being performed correctly. Weighted cones should be worn for 15
minutes twice daily while walking or standing.
Kegel exercises improve the urethral support and closure mechanisms,
particularly during activities such as coughing or bending. Therefore, Kegel
exercises are notably helpful for
stress incontinence due to the effects of pregnancy in women or
Prostatectomy (surgical removal of the prostate) in men.

Klinefelter's syndrome - Perhaps the best
known of the genetic disorders that cause infertility in men. It is found in
roughly 1 out of every 500 live births and often is not diagnosed before
puberty. Patients with this condition have an extra "X" chromosome, one of the
two sex chromosomes in humans. Normal women have two X chromosomes (XX), whereas
normal men have an X chromosome and a Y chromosome (XY). This produces the
genetic signature "XXY" and represents a total of 47 chromosomes within each
bodily cell (the usual number is 46). Klinefelter's syndrome causes testicular
failure due to sclerosis (hardening) of the seminiferous tubules within the
testes (see also Anatomy & Physiology). ). In some individuals with
Klinefelter's syndrome, genetic patterns variant (karyotypes) such as "XXYY,"
"XXXY," or "XXXXY" have been detected. Skeletal abnormalities are more common
among men with multiple X chromosomes. Patients with chromosomal "mosaics" (XXY/XY) have a less severe form of Klinefelter's syndrome and may be fertile,
since a normal ("XY") group of sperm-producing seminiferous tubules may exist
within the testes.
Klinefelter's syndrome typically results in sterility. Although sexual
function may be normal, sperm are not produced to father children. In adolescent
boys, Klinefelter's syndrome may create distinguishing physical features, such
as small firm testes, gynecomastia (overdevelopment of the male breasts), slowed
growth of facial hair, and incomplete masculine body build. Most young men with
Klinefelter's syndrome are tall (the average height is approximately 6 feet),
yet they may not be coordinated or athletic. Psychological, social and learning
problems are common in this group, as is mental retardation. Other associated
conditions include glucose intolerance (inability to metabolize the sugar
glucose) and varicose veins in the legs.
High levels of gonadotropins are usually found in the blood, and semen
samples show azoospermia (lack of sperm). Also noteworthy is the imbalance in
blood levels of estradiol (a form of the female sex hormone estrogen) versus
androgen (male sex hormone). Although most adult men with Klinefelter's syndrome
have normal sexual function (with adequate erection and ejaculation), some may
be impotent and/or have a low sex drive, and they may exhibit incomplete
development of the scrotum or penis.
Sex hormone therapy may be very beneficial for prepubescent boys with
Klinefelter's syndrome, especially if their blood testosterone levels are low.
Specialists generally recommend hormone therapy to ensure optimal sexual
development in such cases - including growth of pubic and facial hair, increased
size of the penis and scrotum, deepening of the voice, and increased muscular
size and strength. This includes use of synthetic testosterone (male sex
hormone) in the form of intramuscular injections, oral or buccal
(through-the-gum) preparations, or transdermal (skin) patches. This treatment,
however, does not repair the sperm production problems.

Laboratory Tests - In addition to imaging, the physician
probably will prescribe one or more laboratory tests to confirm the presence of RCC.
|
|
laparoscopic lymph node dissection:
If a perineal prostatectomy is contemplated then prior to the operation the
pelvic lymph nodes are sampled via three small incisions made in the abdomen,
much like the procedure used to remove gallbladders.

laparoscopy:
Surgery using an laparoscope to visualize internal organ through a small
incision. Generally less invasive than traditional surgeries requiring a shorter
recovery period.

Lasers - In recent years, science has adapted the
use of high-energy light beams called lasers to a variety of surgical
applications. Prostate surgery involving the use of lasers is becoming
increasingly common. Some studies suggest it offers advantages over conventional
prostate surgery, particularly in men with smaller prostates, for whom such
procedures as TURP might be considered unsuitable. The following are the main
laser treatments.

Lawrence-Moon-Biedl Syndrome - Also an
inherited disorder. Like Prader-Willi syndrome, the hypogonadism in Lawrence-Moon-Biedl syndrome is believed to be caused by a hypothalamic
deficiency of GnRH. This disorder is associated with a number of additional
abnormalities, such as mental retardation, extra fingers and/or toes (polydactyly), and retinitis pigmentosa (hereditary eye diseases in which there
is progressive loss of sight).
|
|
Leak Point Pressure - Leak point pressure is a relatively
new test that is used to assess the function of the urethra. It is measured
during a cystometrongram. There are different types of leak point pressure
tests. The first, abdominal (or stress/Valsalva) leak point pressure (ALLP)
measures the ability of the urethra to resist the force of abdominal pressure.
Detrusor (or bladder) leak point pressure (BLLP) measures the resistance of the
urethra to the voiding force of the bladder. The two measurements are not
related to each other.
Valsalva: The abdominal leak point pressure (ALLP) is the lowest total
bladder pressure at which leakage occurs during prompted increases in abdominal
pressure. The patient's bladder is filled by a catheter. The Valsalva maneuver
(a forced exhale with a closed nose and mouth) then is used to increase
abdominal pressure and to spur urine leakage. If the Valsalva maneuver does not,
by itself, result in urine leakage, the patient is asked to perform a series of
coughs. Fluoroscopy (X-ray projection on a fluorescent screen) can be used to
detect the lowest total bladder pressure for leakage. An abnormal ALLP indicates
that something is wrong with the internal sphincter muscle. Therefore, the ALLP
test can accurately determine the presence or absence of
stress incontinence.
Bladder: The bladder leak point pressure (BLLP) is the highest total bladder
pressure achieved at the time that urine begins to leak. The BLLP may occur at
very large urine volumes and very high pressures in some patients. A high
(greater than 40 cm water pressure) BLLP may suggest a tendency towards
deterioration (breakdown) of the upper urinary tract.
|
|
Lipoma - Among the rarest of renal tumors,
lipomas appear to originate in the fat cells within the renal capsule or
surrounding tissue. They typically occur in middle-aged women, can grow very
large and produce pain and hematuria. Like many benign tumors, they are
suspected of harboring potential for turning cancerous, and usually are treated
with surgical excision, typically involving total nephrectomy.
|
|
lithotripsy:
A procedure done to break up stones in the urinary tract using ultrasonic shock
waves, so that the fragments can be easily passed from the body.
|
|
|
|
|
|
|
|
|
Lithotryptor (litho=stone, tryptor=cruncher). Using high
energy shockwaves stones can be crushed into small pieces. For the shockwaves to
be able to reach the stone, the patient used to be partly immersed in water - a
kind of bathtub - in the early days of external lithotripsy; water is a good
conductor of these shockwaves (the body itself is composed mainly of water).
Nowadays, a small water bath or a watery gel is sufficient for treatment. During
treatment, the patient is positioned on a large table, in which the shockwave
machine is inbuilt. An
X-ray and/or
ultrasound device is also built into the table and is used to pinpoint the
stone in the patient and target the focus of the shockwaves. During the
treatment session, a couple of thousand shockwaves are fired at the stone in
rapid succession. Because it is possible to target the shockwave focus very
precisely (the focal width is only a few millimeters), only the stone is really
hit, although still quite some of the shocks hit the surrounding tissue instead
because with every breath the kidney moves up and down. The treatment takes
30-45 minutes and is tolerated well, although some pain can result from the
bouncing of the stone. After treatment, there is often some numb feeling of the
skin due to the tiny shockwaves that have been bombarding it. The treatment is
generally quite effective, although in some cases (big stones) several sessions
may be needed to fully disintegrate the stone.

Lymph Nodes and Lymphadenectomy - Lymph nodes are round or
oval bodies that supply white blood cells to the circulatory system. These
cells, called lymphocytes, typically remove bacteria and foreign particles from
the blood. But when cancer cells invade the bloodstream, they can be spread to
other parts of the body, including the lymph nodes.
When prostatic cancer spreads, it usually migrates first to the lymph nodes
in the pelvis. The doctor can estimate the likelihood of this spread on the
basis of the biopsy results, PSA tests, and the size of the tumor. He or she
also may recommend removing these nodes for microscopic examination.
If it appears likely that the cancer has spread, the doctor may recommend
having them surgically removed through an incision in the lower abdomen. This
procedure, called surgical lymphadenectomy, can be done at the same time that
the cancerous prostate is removed (radical prostatectomy). Because the body has
many lymph nodes, the loss of a few in the pelvic region does not cause a
problem.
The doctor also may examine and remove the nodes with a laparoscope, a
miniature telescopic device connected to a monitor. This device is inserted
through four small incisions in the lower abdomen. Laparoscopic lymphadenectomy
requires less recovery time in hospital for the patient than an open lymphadenectomy. But because it constitutes a second surgical procedure, the
desirability of performing this process must be assessed relative to the need to
remove the prostate as well. If it appears that a radical prostatectomy will be
necessary, the doctor and patient may elect to remove both in a single
operation.

Magnetic Resonance Imaging (MRI) - Similar in some respects
to a CAT scan, an MRI uses large magnets to project magnetic waves through the
body and create computer-generated cross-sectional images of internal organs.
|
|
Matrix - Another chemical component of urine, a
noncrystalline mucoprotein called matrix, is thought by many experts to play a
role in stone formation, although the precise nature of that role is still
unclear. In persons who do not develop stones, matrix seems to act as an
inhibitor. However, among patients who suffer from stones, matrix appears to be
an initiator, and may even provide the chemical framework upon which crystals
develop.

menopause:
The period that marks the permanent cessation of menstrual activity, usually
occurring between the ages of 40 and 58.

metastasis:
The spreading of a cancerous tumor to another part of the body.

|
Methylprednisolone - Methylprednisolone is
a corticosteroid medication that has been prescribed as a treatment for
immunologic infertility. In particular, methylprednisone is used to suppress
blood levels of antisperm antibodies (see also Other Sperm Function Tests ). In
men, the drug is given a specific number of days before the female partner's
time of ovulation (fertile period).
Methylprednisolone therapy is very controversial, since, with the high doses
required (96 mg daily), it can produce many side effects that are associated
with other forms of steroid therapy - that is, worsened peptic ulcer disease,
skin disorders, glucose intolerance (inability to metabolize the sugar glucose)
and mental disorders. Success rates are varied, but very few studies have shown
much benefit.
|
|
microwave (targis):
A catheter is placed within the bladder and positioned within the prostate, then
the antenna emits microwaves. This procedure increases the passageway allowing
for easier urination.
|
|
MICROWAVE HYPERTHERMIA OF THE PROSTATE -Similar to the laser ablation
procedure, transurethral microwave hypertermia of the prostate utilizes heat to
remove prostatic tissue. A microwave probe is placed into the prostatic channel,
microwave energy is utilize to heat the prostate tissue to temperatures above 50
degree Celcius. This causes destruction to the prostate tissue and shrinkage of
the gland. No prostate tissue is removed for pathologic diagnosis. The new
generation microwave machines use a catheter that cools the lining of the
prostatic urethra while the prostate tissue deep inside is heated. This allows
patients to recover with less irritation after the procedure. These new
generation machines also control the delivery of microwave energy and the heat
level they produce more accurately with the advance computer technology that is
employed. The newest machines are available at Columbia Presbyterian Medical
Center as part of several clinical trials across the USA and their results are
promising as an intermediate modality between medical therapy and more invasive
surgical approaches.

Mixed Gonadal Dysgenesis - An inherited
disorder with a distinctive genetic signature (45, XO/46, XY). It is defined by
the presence of a testis on one side and a "streak" (primitive) gonad on the
other side. The mixed character of this disorder is illustrated by the fact that
some patients have external genitalia that appear female (although ovaries are
not present internally), whereas others appear like normal men with one-sided cryptorchidism. If a patient with mixed gonadal dysgenesis has been reared as a
male and has a normally descended testicle, then he may be fertile.
There is a high probability of malignant (cancerous) transformation in the
tissues of the undescended testis and/or streak gonad among adults with this
disorder. Nonmetastasizing (nonspreading) gonadoblastomas are the most
frequently occurring tumors, but germinal cell tumors - which do metastasize -
may occur along with them. Thus, most physicians recommend early removal of the
gonads (except scrotal testes).
|
|
mixed incontinence:
Having both stress and urge incontinence.
|
|
Myotonic dystrophy - An inherited disorder
that is characterized by delayed muscle relaxation after initial contraction.
Individuals with the disorder usually have physical features such as frontal
baldness and opaque regions within the lens of the eyes. Gynecomastia (overdevelopment of the male breasts) does not occur. Although puberty may be
normal in affected men, myotonic dystrophy causes testicular atrophy (shrinkage)
in a large percentage of adults (up to 80%). Such atrophy is attributed to
abnormalities of the seminiferous tubules. Blood levels of follicle-stimulating
hormone (FSH) are usually increased in proportion to the degree of testicular
atrophy.
Although some spermatogenesis (sperm production) may be present, testicular
biopsy usually shows disorganization of the sperm maturation process, with
breakdown of primitive germ cells that ultimately become sperm and
sperm-nourishing Sertoli cells of the seminiferous tubules, and eventual tubular
sclerosis (hardening) (see also Normal Process of Sperm Development).
Because testosterone levels are normal in most men with myotonic dystrophy,
no androgen (male sex hormone) therapy is necessary. Unfortunately, there is no
treatment for infertility due to testicular damage in myotonic dystrophy
patients.

Needle Suspension - Needle suspension procedures are simpler
than abdominal suspension procedures and are less invasive (because they require
smaller/fewer incisions and punctures). A surgeon named Pereyra first described
transvaginal (through the vagina) needle suspension in 1959. Since that time,
numerous surgical adaptations have been developed, each named after its creator (Stamey, Raz, Gittes, etc.); however, the principles of needle suspension remain
the same.
In essence, sutures are placed blindly through the pubic skin or via vaginal
incision into the anchoring tissues on each side of the bladder neck. The
bladder neck then is supported by the sutures, which are threaded on a needle
and tied to the fascia (fibrous tissue) or the pubic bone. Operative times and
recovery periods are shorter for needle suspension versus other suspension
techniques. Some healthcare facilities even conduct needle suspensions as
outpatient procedures.
The Stamey technique can be performed both vaginally or through a small
incision above the pubic bone. A nylon suture is used to suspend the urethra on
each side. Cystoscopy is employed to ensure that the urethra and bladder are not
injured during the procedure. (Note: When endoscopy -- visual examination of the
bladder by means of a tiny, telescope-like device connected to a video camera --
is used to examine the organs of the abdominal cavity, the procedure is called laparoscopy.)
The Raz procedure often is chosen for patients who are incontinent due to
urethral and bladder neck hypermobility (dropping down) and who have minimal or
no cystocele (herniation of the bladder into the vagina). An inverted U-shaped
incision is made at the base of the anterior (front) vaginal wall, and adhesions
(fibrous tissue bands) around the bladder neck and urethra are released. A
needle is passed through the surgical incision, and the suspending sutures are
pulled up, lifting the front of the vagina and urethra. The Raz procedure is
very similar to the Stamey procedure, but the sutures are not placed near the
urethra; instead, they are placed in the front of the vaginal wall.
The Gittes procedure is a transvaginal technique that does not require an
incision. Instead, a small puncture is made above the pubic fat pad. A suture is
then transferred by a needle through the rectus (muscle of the pubic crest) and
down toward the vaginal wall, where it is looped and drawn back and out through
the puncture. A second pass is made through the same incision (1 or 2 cm beside
the first pass) to create a strong support for the suspension. The process is
repeated through another puncture hole, which is made 1.5 to 2.0 cm away from
the first site. Both suspending sutures are tied down within their respective
puncture sites.
Bone anchors are new additions to the techniques for needle suspension of the
bladder neck. When needle suspension was first developed, surgeons questioned
the amount of tension that was suitable for the suspension sutures. They wanted
to avoid the complications of bladder outlet obstruction and suture breakdown
that could because by too much tension or sutures pulling out of the anchoring
tissue.
Recent innovations, such as the vesica® bladder suspension kit and Intac/Infast kits, employ bone anchoring devices to improve the needle
suspension procedures.
With vesica®, a disposable suture carrier creates a large Z-stitch that is
used move pubic fascia beside the bladder neck and urethra. Next, the suspension
sutures are fixed to an anchor that is inserted into the pubic bone and they are
tied without tension by means of a removable spacer. Bone anchoring is not a
very painful procedure and can be performed on an outpatient basis.
Patients with severe
stress incontinence and intrinsic sphincter deficiency (Type III SUI or
weakening of the urethra muscle) may not be helped by simple suspension
procedures. Yet such individuals are good candidates for the pubovaginal sling
procedure, which can create the urethral compression necessary to achieve
bladder control.
This technique involves the creation of an autologous sling -- that is, a
sling made out of a strip of tissue from the patient's own abdominal fascia
(fibrous tissue). Occasionally, surgeons use a synthetic (artificial, man-made)
sling for this procedure, although urethral erosion (breakdown) appears to be
more common when synthetic slings are used.

nephrectomy:
Removal of an entire kidney.
|
|
Nifedipine (Procardia) is a treatment for heart disease and high blood
pressure, but it has reduced bladder pain and urgency in some IC patients.
Recent studies have suggested that heart disease patients may have more heart or
other problems if treated with nifedipine than with other heart medications. It
is not known whether these findings would apply to IC patients without heart
disease.

NMP22TM assay - The NMP22TM assay measures specific proteins from the
nuclear matrix (cell center). It can detect transitional cell carcinoma (TCC)
with a sensitivity of roughly 67%, meaning that 67% of existing TCCs are
detected. But, perhaps more importantly, the NMP22TM assay it is able to predict
the recurrence of bladder cancer after transurethral resection (TUR) for
invasive cancer with an overall sensitivity of 70% (see also Treatment of
Bladder Cancer). The BTA TRAK® test measures the levels of a specific protein
(human complement factor H-related protein, or hCFHrp) that is detected by the
BTA stat test.
|
|
Noninvasive/External Devices - Several noninvasive, or
external, devices are among the newer promising treatments for stress
incontinence.
The Miniguard Patch and Impress (Uromed) are single-use foam pads that are
slightly larger than a postage stamp. One surface of the patch is covered with a
gel-like glue that adheres to the region around the opening of the urethra. The
patch fits between the labial folds and provides opposing pressure on the
urethra to prevent leakage. When the wearer wants to urinate, she simply removes
the patch and applies a new one afterward. The patch is less bulky than
cumbersome pads and provides a neater alternative for leakage.
FemAssist and Bard Cap Sure Continence Shields are external devices that
function like foam pads, but can be reused used for about one week before being
replaced. Both are small, circular, silicone rubber devices that are positioned
over the flat area surrounding the urethra. Using suction, they support and
reinforce the muscle that naturally control urine output and help prevent
accidental urine loss in women who suffer from stress incontinence. An ointment
is used to create a mild vacuum seal that holds the device in place. When a
woman wants to urinate, she removes the device, which can then be cleaned and
reapplied. Because they are used externally, FemAssit and CapSure have lower
rates of associated infection than internal devices, though some woman report
discomfort or mild irritation when using these products.

|
Noonan Syndrome (male Turner's syndrome) -
Noonan syndrome is the male expression of Turner's syndrome, which is
characterized by the genotype "XO." Men with Noonan syndrome usually are
infertile due to cryptorchidism and insufficient sperm production. Like women
with Turner's syndrome, men with Noonan syndrome have many distinctive physical
features, such as short stature, low-set ears, webbed neck, upper eyelid droop (ptosis), and elbow deformity (cubitus valgus). Cardiovascular abnormalities
also may be present.
Because of the testicular malfunction in these individuals, Noonan syndrome
patients usually have increased blood levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) (see also Normal Process of Sperm
Development) Thus, hormone therapy may help to relieve their androgen (male sex
hormone) deficiencies and crytorchidism, although their impaired sperm
production is untreatable.

OPEN ( SUPRAPUBIC OR RETROPUBIC) PROSTATECTOMY -Prior to the TURP,
prostate obstruction was treated with an formal operation requiring an surgical
incision on the lower aspect of the abdomen to remove a large part of the
blocking portion of the prostate gland. In current practice, it is still applied
to patients with large prostates, prostates with a middle lobe or to patients
who have other condition that requires an open operations such as the removal of
stones in the bladder. Since it is a formal operation, patients are subjected to
the usual risk and complications of an open pelvic operation requiring
anesthesia. In addition, their hospitalization is longer and recuperation with a
catheter and from normal activity is longer. Patients have a scar from their
surgical incision. The long term success rate for the treatment of BPH with this
procedure is similar to the TURP.
|
|
Open Abdominal Surgery - Sometimes incontinence surgery
takes place via an incision through the abdomen. Two standard suspension
procedures that require abdominal incisions are the Marshall Marchetti Krantz
procedure and the Burch procedure.
The Marshall Marchetti Krantz (MMK) procedure is still offered in many
medical centers throughout the United States, but it is no longer a favored
technique. This is because the sutures (stitches) in the procedure are placed
around the urethra, creating the potential for obstruction; in addition, the
surgical entryway limits the physician's ability to correct cystocele (herniation of the bladder into the vagina). During the MMK procedure, the
bladder neck and urethra are separated from the back surface of the pubic bone.
Sutures are placed on either side of the urethra and bladder neck, which are
then elevated to a higher position. The free ends of the sutures are anchored to
the surrounding cartilage and pubic bone.
The Burch procedure, also known as Burch colposuspension (vaginal
suspension), often is performed when the abdomen is already open for another
purpose, such as abdominal hysterectomy (removal of the uterus). During the
suspension procedure, the sutures are placed laterally (sideways), which avoids
urethral obstruction and allows the physician to repair any small cystoceles
that may be present. The bladder neck and urethra are separated from the back
surface of the pubic bone. The bladder neck then is elevated by means of lateral
sutures that pass through the vagina and Cooper's (pubic) ligaments. The vaginal
wall and ligaments are brought together without tension, and the sutures are
tied.
open nephrolithotomy:
is the most invasive procedure for removing kidney stones. Because it is so
traumatic, most kidneys can withstand no more than two such operations. Deep
anesthesia is required, after which the surgeon makes a large (10-20 centimeter)
incision in the patient's back or abdomen, depending upon where the stone is
located. Either the ureter or the kidney isopened and the stone extracted. Most
patients require prolonged hospitalization afterward, and recovery may take up
to two months.
|
|
Open Prostatectomy - If the prostate is greatly
enlarged, if the bladder has been damaged and must be repaired, or if the
patient has other complications prohibiting transurethral surgery, an open
surgical procedure called a prostatectomy (removal of the prostate) may be
necessary.
With this procedure, the patient is anesthetized and the surgeon makes an
external incision, either in the lower abdomen or in the perineum (the area
between the rectum and the scrotum), depending upon the location of the enlarged
portion of the prostate. The surgeon then removes the enlarged prostate tissue
from inside the gland. An open prostatectomy in which the surgeon accesses the
prostate from the abdomen is called suprapubic (surgery from on top or above);
surgery through the perineum is called retropubic (surgery from the back or from
behind).
|
|
Oral Drugs - All drugs--even those sold over-the-counter--have side
effects. Patients should always consult a doctor before using any drug for an
extended time.
|
|
orchiectomy:
The surgical removal of one or both of the testicles.
|
|
orchitis:
Inflammation of a testicle.
|
|
Other Alpha Adrenergic Agonists - Other Alpha Adrenergic
Agonists include ephedrine and epinephrine and norepinephrine. Since the actions
of these drugs are so widespread within the body, they are not specifically
indicated for incontinence and should be prescribed with caution. The
significant side effects of these drugs are hypertension, tachycardia (fast
heartbeat) and arrhythmia (irregular heartbeat).
|
|
overactive bladder:
A condition characterized by involuntary bladder muscle contractions during the
bladder filling phase which the patient cannot suppress.
|
|
overflow UI:
Leakage of small amounts of urine from a bladder that is always full.
|
|
Oxybutynin chloride (Ditropan) - Oxybutynin is an anticholinergic drug
medication that also directly relaxes bladder smooth muscle. It is prescribed
for
neurogenic bladder patients, and patients who have symptoms of bladder
instability with voiding: that is, patients with
urge incontinence, frequency, urinary leakage, or painful urination. The
typical dosage is 2.5-5.0 mg to be taken orally 3 to 4 times/day). Oxybutynin's
notable side effects are dry mouth, dry skin, visual blurring, nausea and
constipation.
Oxybutynin chloride (Ditropan) and a blend of atropine, hyoscyamine, methenamine, methylene blue, phenyl salicylate and benzoic acid (Urised) may
help reduce bladder spasms that can cause frequency, urgency, and nighttime
trips to the bathroom. Urised may also inhibit the growth of organisms in the
urine.
|
 |
|
P |
|
Partial Nephrectomy - In some cases it may
be possible to remove only the cancerous tissue and part of the kidney,
particularly if the tumor is small and confined to the very top or bottom of the
kidney. A partial nephrectomy also may be the procedure of choice for patients
with RCC in both kidneys or those who have only one functioning kidney.
|
|
Pathology - Broadly speaking, the individual cells that make
up RCC tumors fall into four categories, defined by their appearance under
microscopic examination: clear cell, granular cell, mixed clear and granular,
and sacromatoid or spindle-type. Most studies suggest that the type of cancer
cell present indicates the relative aggressiveness of the disease.
Under a microscope, clear cell cancers are the least "abnormal-looking" --
they are rounded or polygonal-shaped and contain an abundance of fat and sugar.
The tumors they produce are yellow-to-orange in color. Clear cell cancers are
thought to be the least aggressive (likely to spread) and respond more favorably
to treatment.
Few tumors contain only clear cells, however. Darker granular cells usually
are present to a varying degree. These have a larger, darker, nucleus and are
full of tiny pink granules called mitochondria. The tumors they produce tend to
be gray to white in color. Mitochondria are small, oval bodies that provide
energy for cell growth. Their presence indicates a more aggressive form of
cancer.
Tumors that contain both clear and granular cells are considered mixed. This
is the most common form of RCC and indicates the most aggressive form of kidney
cancer.
Mixed tumors that contain spindle-shaped, sacromatoid cells generally are
regarded as having the least favorable prognosis. Although tumors composed
exclusively of spindle cells are uncommon, the relative presence of sacromatoid
cells indicates a form of cancer that tends to grow and spread more quickly.

pelvic muscle exercises:
Pelvic muscle exercises are intended to improve your pelvic muscle tone and
prevent leakage for sufferers of Stress Urinary Incontinence. Also called Kegel
exercises. (see biofeedback)
|
|
|
|

|
|
|
|
Pelvic Muscle Rehabilitation -Pelvic
muscle rehabilitation involves implementation of a comprehensive group of
progressive exercises aimed at strengthening the levator muscle. These exercises
have been used to treat several types of urinary incontinence but are most
frequently employed in patients diagnosed with stress incontinence. The use of
biofeedback during exercise allows patients to observe the duration and strength
of contractions. It has been estimated that pelvic muscle rehabilitation
produces complete resolution of symptoms in 20% of patients and that
improvements in incontinence are observed in 50% to 75% in most of those
treated.
|
|
Pelvic Surgery - Like pregnancy and childbirth, pelvic surgery can
weaken and damage the pelvic floor muscles. As a result, the pelvic floor
muscles may no longer be able to provide the necessary support to the bladder
neck and urethra, and these structures may drop freely when downward pressure is
applied. This condition, which is known as hypermobility, causes incontinence
during physical activity, when the urethra cannot close tightly enough to resist
increased abdominal pressure on the bladder.
Urinary incontinence can result from common forms of pelvic surgery,
including abdominal resection for colorectal (intestinal) cancer, gynecologic
(female genital tract) surgery such as radical hysterectomy (complete removal of
the uterus) or hysterectomy for benign (noncancerous) disease, and failed
prolapse (restabilization) surgery for stress urinary incontinence.
Most patients with postoperative incontinence have either detrusor
instability (DI or unstable bladder: an involuntary, downward-pushing
contraction of the bladder) or urethral/bladder neck incontinence (abnormal
function) due to nerve damage. Successful management of DI incontinence usually
can be achieved by drug therapy and urinary catheterization (passage of a tube
through the urethra into the bladder to drain urine into a bag outside the
body); patients with bladder neck incontinence may require additional surgical
measures.
Pentosan polysulfate sodium (Elmiron) reduces bladder discomfort and
pain in some people with IC. Doctors don't know exactly how the drug works, but
they believe it may repair leaks in the bladder lining. Elmiron is the first
oral drug developed for IC and was approved by FDA in the Fall of 1996.

Percutaneous lithotripsy (per=through, cutis=skin) the stone
in the kidney is reached with a scope through a small wound in the skin and
through the tissues of the kidney. The exact location of the stone is monitored
with the
ultrasound device. Like in the
transurethral lithotripsy the stone is then disintegrated with an
oscillating device. This technique is used in cases of large stones, when a
treatment with the
external lithotryptor would take too much time and too many sessions and/or
in cases of obstruction of the outlet of the kidney in which the kidney could be
damaged if it takes too long to treat the stone. General anesthesia is
necessary, although the treatment is generally very well tolerated by patient
and kidney.
|
|
percutaneous nephrolithotomy (PCN):
Percutaneous means "though the skin." In PCN, the surgeon or urologist makes a
1-centimeter incision under local anesthesia in the patient's back, through
which an instrument called a nephroscope is passed directly into the kidney and,
if necessary, the ureter. Smaller stones may be manually extracted. Large ones
may need to be broken up with ultrasonic, electrohydraulic or laser- tipped
probes before they can be extracted. A tube may be inserted into the kidney for
drainage.
|
|
Percutaneous Slings - The pubovaginal sling involves the
creation of an autologous sling -- that is, a sling made out of a strip of
tissue from the patient's own abdominal fascia (fibrous tissue). Occasionally,
surgeons use a synthetic (artificial) sling for this procedure, although
urethral erosion (breakdown) appears to be more common when synthetic slings are
used.
During the pubovaginal sling procedure, a strip of fascia is obtained via an
incision above the pubic bone. This strip of fascia becomes the sling. Another
incision is made in the front of the vaginal wall, through which the surgeon can
grasp the sling and adjust its tension around the bladder neck. The sling itself
has sutures attached to it.
The sling is secured in place when the two sutures are loosely tied to each
other above the incision in the pubic fascia, providing a hammock for the
bladder neck to rest on.
The pubovaginal sling procedure generally results in high success rates, with
bladder control lasting more than 10 years. Some of the possible complications
of pubovaginal sling procedures are accidental bladder injury, wound infections
and prolonged urinary retention.
|
|
periurethral bulking injections:
A surgical procedure in which injected implants are used to "bulk up" the area
around the neck of the bladder allowing it to resist increases in abdominal
pressure which can push down on the bladder and cause leakage.
|
|
Phenylpropanolamine hydrochloride - Phenylpropanolamine
hydrochloride is found in many prescription and nonprescription cough/cold
preparations and antihistamines (anti-allergy drugs). A typical dosage for
bladder control is 25-75 mg in sustained- released form, twice a day. Phenylpropanolamine, like all other alpha adrenergic agonists, should not be
used by individuals with obstructive forms of incontinence; it should be used
with caution by individuals with hypertension (high blood pressure),
hyperthyroidism (overactive thyroid gland), arrhythmia (irregular heartbeat),
and angina (heart pain caused by decreased oxygen supply to the heart muscle).
|
|
Physical Exam and Medical History - The process usually
starts with a thorough physical examination to assess the patient's overall
health and gather as much information as possible about his or her symptoms. A
medical history check also will be performed to determine if any known risk
factors associated with RCC are present.
|
|
Postoperative Prognosis - The natural
course of renal cell cancer is more unpredictable than that of most tumors. It
is the second most common tumor to undergo spontaneous regression following
removal of the primary lesion; this occurs about 0.5% of the time.
|
|
post-void residual (PVR) volume:
A diagnostic test which measures how much urine remains in the bladder after
urination. Specific measurement of PVR volume can be accomplished by
catheterization, pelvic ultrasound, radiography, or radioisotope studies.
|
|
Prader-Willi Syndrome - An inherited,
secondary hypogonadism disorder. Affected male infants may show reduced muscle
tone at birth. Some of the distinguishing features of Prader-Willi syndrome
include small testes, diminished mental capacity and obesity. It is believed
that the disorder is caused by a defective mechanism of gonadotropin-releasing
hormone (GnRH) secretion by the hypothalamus.
Infertile men with Prader-Willi syndrome may benefit from hormone therapy.
Specifically, blood testosterone levels may increase following human chorionic
gonadotrophin (HCG) administration, and luteinizing hormone (LH) and
follicle-stimulating hormone (FSH) levels may increase in response to chronic
GnRH therapy.
|
|
Preoperative Radiation Therapy - Preoperative radiation therapy is
another strategy that has been used for bladder cancer treatment. The theory is
that radiation exposure will "sterilize" tumor outgrowths, regional lymph node
metastases, and any tumor cells that are spread during the process of cystectomy
(bladder removal). Radiation therapy also is used to shrink the tumor before
surgery. Preoperative radiation sometimes is given in a short-course schedule of
2,000 CGy over a 1-week period. But survival results from clinical studies have
been conflicting. In addition, preoperative radiation may cause a significant
delay in the performance of cystectomy. Therefore, there is a tendency for
American physicians to omit radiotherapy prior to cystectomy in patients with
invasive bladder cancer. Exceptions to this include patients with invasive
squamous cell carcinoma (SCC) or bilharzial bladder cancer.
|
|
Pressure Flow Study - Pressure-flow is one of the most
important and difficult urodynamic studies to perform and interpret. Yet
pressure-flow measurement is essential for the proper understanding of altered
mechanisms in urinary incontinence. In particular, pressure-flow study can help
to define problems such as bladder outlet obstruction (blockage), which is a
major factor in the treatment of men with
Benign Prostatic Hyperplasia (noncancerous overgrowth of the prostate) and
in the pre-operative assessment of women who are considering surgery for
incontinence.
To conduct the test, the patient is catherized with a pressure sensor and the
bladder is filled. When the patient feels a strong desire to urinate, he or she
is asked to void around the catheter into the uroflowmeter (combining a uroflow
with a cystometrogram). Soon afterward, technicians measure the amount of urine
remaining in the patient's bladder. The patient may undergo placement of a
rectal catheter (a tube-like instrument positioned in the anus, the opening of
the large intestine). The pressure-flow recording is made when the patient feels
the urge to urinate.
As previously noted, the analysis of a patient's pressure flow results can
help to diagnose bladder outlet obstruction. Pressure flow study plays an
important role in the evaluation of male patients with lower urinary tract
symptoms (LUTS). Pressure flow study in women is not as clear-cut as in men,
because women tend to void in a different manner and at different pressures.
Moreover, women may respond to obstruction by reducing their urine flow, rather
than by raising detrusor (bladder muscle) pressure. Therefore, some experts
recommend pressure flow studies in female LUTS patients only after prior
incontinence therapy or surgical repair of the urinary tract.

Primary Hypogonadism - delayed sexual maturity due to
abnormalities within the gonads themselves - is a defining characteristic of
many genetic disorders associated with male infertility. Men with primary
hypogonadism usually have severe, irreversible testicular defects because of
genetic abnormalities.
|
|
Propantheline bromide (Pro-Banthine) - Although bladder
spasm is not an FDA-approved indication for this drug, propantheline has been
widely prescribed over the years for the treatment of
urge incontinence (typical dosage: 7.5-30 to be taken without food 3 to 5
times/day). It is a classic anticholinergic medication that stops muscle
contractions in the normal bladder. Some of the unwanted side effects of
propantheline include dry mouth, visual blurring, nausea, constipation,
tachycardia (fast heartbeat), drowsiness and confusion. Propantheline is
specifically contraindicated (improper) for patients with obstructive urinary
tract disorders and for those with narrow-angle glaucoma (eye disease
characterized by high pressure within the eye).
|
|
prostaglandin:
Any of various oxygenated unsaturated cyclic fatty acids of animals that have a
variety of hormonelike actions (as in controlling blood pressure or smooth
muscle contraction).
|
|
Prostate Biopsy - Once the physician has diagnosed a likely
cancerous prostate condition by means of a digital rectal exam or a PSA test, he
or she may want to perform other tests to determine the type of cancer, its
location, and stage of development.
Prostate biopsies is done with a needle similar in size to those used to draw
blood or administer injections. A sample of tissue from the suspected cancer
site is extracted and analyzed by a pathologist (a physician who is a specialist
in diseases) to confirm the presence of cancer and to determine its type.
A patient undergoing a prostate biopsy is advised to abstain from alcohol,
aspirin, or non-steroid anti-inflammatory drugs for one week before the
procedure. He also is required to have a Fleet enema and to take an oral
antibiotic (usually ciprofloxacin) for 1 day before and 2 days after the biopsy.
The biopsy is performed with the patient lying on his side. A biopsy needle
may be inserted through the perineum into the tumor, or a probe, guided by a
transrectal ultrasound (TRUS) device, may be inserted into the rectum, and a
needle projected into the tumor through a port in the tip of the probe. A cell
sample is then extracted into a syringe and taken for analysis by the
pathologist. Samples may be taken from several parts of the tumor.
While the biopsy is a valuable conventional procedure, it also carries risks.
It may produce bleeding that is difficult to control, or it may cause infection
from rectal bacteria.
Additionally, doctors and researchers have noted that biopsy of a cancerous
tumor can cause spreading or "seeding" of cancer cells along the path or track
made by the biopsy needle. This could cause cancer that had been confined solely
to the prostate capsule to spread into surrounding tissues, making a serious
health concern even more problematical.
While cancer seeding from biopsy is uncommon, patients and physicians should
be aware of these potential risks, have a clear understanding of what
information they want to obtain from a biopsy, and what action will be taken
based upon that information.
|
|
Prostate Specific Antigen (PSA) Test - If the physician
suspects the presence of a tumor on the prostate, he or she will likely perform
an additional blood screening test called the prostate specific antigen, or PSA
test. This procedure can provide information about how much cancer is present
and whether it has spread.
Prostate specific antigen is a substance produced only by the cells of the
prostate capsule (membrane covering the prostate) and periurethral glands. The
test measures the amount of PSA present in the blood. An elevated or rising PSA
level can indicate the existence of prostate cancer.
PSA is measured in nanograms per milliliter (ng/ml) of blood. A PSA of 4 ng/ml
or lower is normal and a PSA above 10 ng/ml suggests the presence of cancer; the
range 4-10 ng/ml is a gray area, and readings in this range are considered
inconclusive.
Additionally, PSA levels are also related in part to the size of the
prostate, and patients with benign prostatic hyperplasia (BPH) or a prostate
inflamed by prostatitis also produce elevated levels of PSA. For these reasons,
scientists have modified the PSA testing process by developing several new PSA-based refinements:
Free/Total PSA (also known as PSA II) -- PSA in the blood may be bound
molecularly to a variety of serum proteins, or it may exist in a free or unbound
state. Total PSA is the sum of all existing forms; Free PSA constitutes the
unbound PSA only. Studies suggest that malignant prostate cells produce less
Free PSA. Therefore, a low proportion of Free PSA in relation to Total PSA might
indicate a cancerous prostate, and a high proportion of Free PSA might suggest a
normal prostate or a condition reflecting BPH or prostatitis.
Age-specific PSA -- Evidence suggests PSA levels increase with age.
Researchers have defined typical age-associated values for PSA norms. A PSA of
up to 2.5 ng/ml for men age 40-49 would be considered normal, as would those up
to 3.5 ng/ml for men 50-59, 4.5 ng/ml for men 60-60, and 6.5 for men 70 and
older. Lower PSA levels in older men might indicate the presence of cancer that
does not need to be treated aggressively, whereas higher levels in younger men
might warrant aggressive treatment.
PSA Velocity (PSAV) -- Researchers have studied the rate of change in PSA
over time in men whose medical outcomes were known. This rate of change in PSA
is known as PSA velocity (PSAV). A rate of change in PSA velocity of 0.75 ng/ml/yr
or higher has been conclusively linked to clinically significant prostate
cancer. Therefore, a man with a PSA in the gray area of 4-10 ng/ml, and who is
found to have a PSAV of 0.75 ng/ml/yr, may have a cancerous prostate condition.

prostate:
A muscular, walnut-sized gland that surrounds part of the urethra. It secretes
seminal fluid, a milky substance that combines with sperm (produced in the
testicles) to form semen.
|
|
prostatectomy:
Surgical removal of the prostate.
suprapubic / retropubic prostatectomy: This involves the removal of obstructing prostatic tissue
through a supra-pubic incision ( a cut below the belly button ). The Prostate
is not wholly removed. Suprapubic Prostatectomy requires incising the
bladder to remove the obstructing tissue while a Retropubic approach
involves incising the Prostatic capsule to remove the obstructing tissue. Both
approaches utilize an abdominal incision.
radical retropubic prostatectomy: Removal of prostate through an abdominal incision. The
prostate is completely removed. The advantage is that the lymph nodes can be
sampled at the time of the operation and the nerve-sparing procedure is easier
to do via this operation.
perineal prostatectomy: A
Perineal incision is utilized. The advantages are: less blood loss, easier
visualization of the bladder / urethral anastomosis and decreased recovery
time because the incision does not involve muscle or any other vital tissue |
|
Prostatic Acid Phosphatase (PAP) Test - Prostatic acid
phosphatase is an enzyme produced by several types of tissue, including normal
prostate tissue. Its production increases as prostate disease progresses. In
conjunction with other testing procedures, PAP testing has been used to detect
and monitor advanced prostate cancer. It is not, however, used by itself in
diagnosing prostate cancer.
|
|
Prostatic Stents - A prostatic stent is a tiny,
spring like device inserted into the urethra. When expanded, it pushes back the
surrounding tissue and widens the urethra to permit an increased flow of urine.
Prostatic stents are most often used for patients who have other medical
problems that prohibit medication or surgery. Prostatic stents have several
advantages:
· They can be placed in less than 15 minutes under regional
anesthesia.
· Bleeding during and after surgery is minimal.
· The patient can be discharged the same day or next morning.
The disadvantages of stents are:
· Prepositioning them can be difficult.
· They may cause irritation and frequent urination.
· They may move and cause pain or incontinence.
· Removing them-necessary in one-third of patients-can be difficult.
|
|
prostatitis:
Inflammation of the prostate
|
|
Prostatron - Transurethral microwave thermotherapy (TUMT)
does not cure BPH; it reduces its symptoms. TUMT uses a special catheter with a
tip containing an antenna-called a Prostatron-to deliver high-temperature (41°-
44°C) microwave energy to the prostate without affecting adjacent structures.
Depending on the elasticity of the urethra, the therapeutic deep heat will
improve urine flow. A fiberoptic thermosensor monitors temperatures throughout
the procedure, and a cooling system circulates water within the catheter
applicator to protect the urinary tract. The procedure takes about an hour and
is performed on an outpatient basis without anesthetic.
Prostatron therapy does not solve the problem of incomplete emptying of the
bladder, but its benefits are achieved without causing incontinence or
impotence. Most patients resume normal activity immediately after treatment.
|
|
Prosthetic occluding devices - Prosthetic occluding devices can be
used to block the flow of urine by squeezing the urethra shut. For men, such
mechanical devices include penile clamps (for example, the Cunningham clamp) and
compression rings. The penile clamp is a V-shaped casing with a foam cushion
that fits over and under the penis. When closed, the penile clamp should stop
the flow of urine without causing discomfort. Compression devices are adjustable
rings that surround the penis and, when inflated with air, pinch off the urine
flow. Occluding devices usually are reserved for temporary use by individuals
with intrinsic sphincter deficiency. These devices must be removed at regular 2-
to 3-hour intervals to empty the bladder. Therefore, they should be used only by
mentally competent individuals who are able to adjust them by hand and who are
able to remember the bladder-emptying schedule. Improper use of penile clamps
and compression devices can result in penile and urethral erosion, penile edema
(swelling), pain and obstruction.
|
|
Pseudoephedrine Hydrochloride - Pseudoephedrine
Hydrochloride is found in many prescription and nonprescription cough/cold
preparations and antihistamines. A typical dosage for bladder control is 15-30
mg, three times a day.
|
|
pubovaginal sling:
A surgical procedure in which a man-made or cadaveric piece of material is
placed under the bladder neck to support and immobilize. This technique improves
sphincter function and decreases bladder neck movement, improving continence.
|
|
pyelonephritis:
Inflammation of the kidney, usually due to a bacterial infection.
|
|
pyuria:
The presence of pus in the urine; usually an indication of kidney or urinary
tract infection.
|
 |
|
Q |
|
Q-Tip Test - The Q-tip test is a simple procedure that helps
the physician to measure the degree of hypermobility (dropping down) that occurs
in a patient's urethra and bladder neck during urination. Although subjective
and nonspecific, this test may be useful for the diagnosis of
stress incontinence.
The patient lies on his or her back, and a long, well-lubricated Q-tip is
inserted 1 to 2 cm into a cleansed urethra. The patient is asked to strain and
perform a Valsalva maneuver (a forced exhale with a closed nose and mouth). An
exaggerated, upward deflection of the Q-tip (by an angle of more than 35
degrees) is considered evidence of urethral and bladder neck hypermobility.
|

R |
|
Radiation Therapy - Outside of the United States, radiation therapy
(also known as radiotherapy) often is used as a primary (singular) treatment for
invasive bladder cancer. Yet, in America, primary radiation therapy usually is
reserved for people who may not be good candidates for bladder surgery because
of age or certain medical problems. Primary therapy generally involves a
radiation dose of 6,000 to 7,000 rad to the bladder, with or without
corresponding lymph node treatment. High-dose, external beam radiation therapy
may be an alternative to bladder surgery in patients with stage T2 to T3
muscle-invading cancers. Radiation therapy has no role in the management of
carcinoma in situ (CIS, TIS). However, 5-year survival rates are much lower in
radiation-treated patients versus patients who undergo surgical therapy. And,
unfortunately, local reappearance of bladder cancer occurs in up to one-half of
all individuals who receive radiation therapy. Yet people who experience
complete tumor regression after radiation therapy tend to do well. There can be
significant side effects from high-dose external beam radiation therapy,
including radiation cystitis (symptoms of irritation, incontinence, bloody
urine, and fibrosis, a buildup of fibrous tissue), proctitis (inflammation of
the rectum), impotence, and skin reactions.
|
|
Radical Cystectomy - In women with T2 to T3a tumors, a standard
surgical procedure is radical cystectomy (cutting away of the entire bladder and
associated tissues) with pelvic lymphadenectomy. Radical cystectomy in women
includes removal of the uterus (womb), tubes, ovaries, anterior vaginal wall
(front of the birth canal), and urethra (the tube that passes urine from the
bladder out of the body). Preoperative
radiation therapy may have some merit when combined with bladder surgery,
although radiation therapy alone usually is unsuccessful.
|
|
Radical Nephrectomy - The most common form
of surgery for RCC, radical nephrectomy involves removal of the entire kidney,
often along with the attached adrenal gland, surrounding fatty tissues and
nearby lymph nodes (regional lymphadenectomy), depending upon how far the cancer
has spread.
Raz procedure often is chosen for patients who are incontinent due to
urethral and bladder neck hypermobility (dropping down) and who have minimal or
no cystocele (herniation of the bladder into the vagina). An inverted U-shaped
incision is made at the base of the anterior (front) vaginal wall, and adhesions
(fibrous tissue bands) around the bladder neck and urethra are released. A
needle is passed through the surgical incision, and the suspending sutures are
pulled up, lifting the front of the vagina and urethra. The Raz procedure is
very similar to the Stamey procedure, but the sutures are not placed near the
urethra; instead, they are placed in the front of the vaginal wall.

rectocele
A herniation of rectum into vagina
|
|
Renal Adenoma - The most common form of
benign, solid kidney tumor, renal adenomas are typically small, low-grade
growths. Their cause is unknown. Because they usually are asymptomatic, their
incidence in the live population is unknown, although one study found them
present in 7% to 22% of autopsy cadavers. In rare cases, where they have grown
large enough to erode the function of the kidney or adjacent vessels, symptoms
similar to those of RCC have been known to occur.
Adenomas look much like low-grade RCCs under a microscope. In fact, while
they are considered benign, there is presently no known cellular classification
to differentiate them from RCCs. Many researchers and physicians regard them as
early-stage precancers, to be treated accordingly.
|
|
Renal Oncocytoma - Oncocytomas are a type
of benign, usually asymptomatic, tumor that can grow quite large. They can
develop throughout the body and are not unique to the kidneys. Their cause is
unknown, and they appear with greater frequency in men than in women. Typically,
they are discovered incidentally by ultrasound, IVP, CT or MRI scan during an
examination for some other health problem.
Under a microscope, many oncocytomas resemble early-stage RCCs. Many
physicians regard them as precancerous growths to be surgically removed unless
the patient's age or overall health condition dictates otherwise.
|
|
Renal Sarcoma - Another rare form of kidney cancer, renal
sarcoma is a disease of the kidney's connective tissues that accounts for less
than 1% of all kidney tumors. Its symptoms are similar to those of RCC: hematuria, pain in the back or flank, or a lump or mass in the abdomen. In most
cases, it is impossible to differentiate renal sarcoma from RCC externally, so
the diagnosis usually is made after examination of a CT scan or MRI procedure.
Such tumors will grow and spread to adjacent organs, bones and lymph nodes if
left untreated. The only potentially curative form of treatment is surgery,
usually radical or partial nephrectomy, sometimes in conjunction with radiation
or chemotherapy.
|
|
Retrograde Ejaculation - The process of
ejaculation depends upon the normal function of the bladder neck. A variety of
abnormal conditions may interfere with the bladder neck's nerves and/or muscles,
preventing its closure and leading to the backwards, "retrograde" flow of semen
into the bladder.

Sacral Nerve Stimulation-InterStim - InterStim® Continence
Control Therapy is a reversible treatment alternative for people with urinary
urge incontinence who have found behavioral and pharmacological treatments
ineffective or not well tolerated. InterStim® Continence Control Therapy uses a
small stimulation system, about the size of a pacemaker that is surgically
placed under the skin in the lower abdomen and lower back. The therapy uses mild
electric pulses to stimulate a sacral nerve in the lower spine. This nerve
influences the bladder and surrounding muscles that control urinary function.
Clinical studies have shown that nearly half of all urge incontinent patients
using the therapy are completely dry and many others have had their symptoms
reduced significantly. The exceptional success rate of InterStim® Therapy is
linked to the test stimulation procedure. This unique feature allows patients
and their physicians determine the effect of InterStim® Therapy prior to
consideration of a surgical implant procedure.
Done on an outpatient basis, this cost effective and informative test
stimulation procedure:
locates and identifies the integrity of the sacral
nerves
demonstrates the effect of sacral nerve stimulation on
patient symptoms
allows the patient to experience the sensation of
stimulation
helps the clinician and patient make an informed choice
about InterStimTherapy as a long-term therapy option.
During the test stimulation procedure patients are asked to keep a voiding
diary to record voiding patterns with the stimulation. The voiding diary is then
compared to diaries from before the test stimulation procedure and after the
test stimulation procedure to determine the effect of the treatment on their
symptoms.
The test stimulation allows the clinician to evaluate the therapy as an
option for the patient without significant cost or delay. It also provides
patients with realistic expectations about the results of InterStim Therapy.
Usually within three to five days both the patient and clinician can determine
if InterStim® Therapy is a viable treatment option.
After successful evaluation of the test stimulation, the InterStim® System
may be implanted for long-term therapy. The procedure is performed under general
anesthesia, and the InterStim® System can generally be activated on the first
day after surgery.
Potential side effects of the InterStim® Continence Control Therapy include:
pain at the implant sites, lead migration, infection, change in bowel function,
and undesirable stimulation or sensations.

Secondary Hypogonadism (Hypogonadotropic Hypogonadism) - A lack of gonadotropin-releasing hormone (GnRH) - or
deficiencies in pituitary luteinizing hormone (LH) and follicle-stimulating
hormone (FSH) - can produce a variety of conditions defined as secondary
hypogonadism or hypogonadotropic hypogonadism (delayed sexual maturity due to
sex hormone deficiency). These disorders are usually inherited and are linked
with abnormalities of the nervous system, genitals, and other body parts. One
notable abnormality is anosmia - lack of sense of smell. Unlike the untreatable
infertility caused by primary hypogonadism, infertility caused by secondary
hypogonadism often is manageable by appropriate hormone therapy.

Segmental Cystectomy - Segmental cystectomy (partial removal of the
bladder)a bladder-preserving or "salvage" form of surgeryis appropriate only
in a limited selection of male or female patients (for example, patients with
squamous cell carcinomas or adenocarcinomas that arise high in the bladder
dome). When segmental cystectomy is performed, it may be preceded by radiation
therapy (see also Radiation Therapy).
|
|
Semen Analysis - Semen analysis is the
most informative test for male infertility. It is not, however, a conclusive
indicator of fertility versus infertility, since there is still some confusion
about what is required for adequate and healthy ejaculate (expelled semen). And,
more importantly, semen characteristics are not absolute predictors of sperm
function. In spite of these limitations, guidelines - such as those of the World
Health Organization (WHO) - have been established to determine semen quality
limits below which the chance of achieving pregnancy becomes increasingly less
likely (see Table 1). Thus, a semen sample with a sperm count of 50 million
sperm per milliliter of ejaculate, 65% motility, and 60% oval morphology (shape)
would be classified as "normal"; a semen sample with a low sperm count (less
than 10 million/ml), poor forward motility, and 30% oval morphology would be
less capable of producing a pregnancy.
A semen analysis should be repeated at least once and it may be a good idea
to repeat semen analysis periodically as these levels can change over time.
|
|
Sexual Dysfunction - Problem with sexual
performance is an important risk factor for infertility, and sexual dysfunction
is often correctable. Unfortunately, though, sexual dysfunction is a factor that
may not be recognized or emphasized by patients who present infertility problems
to their physicians. Sexual dysfunction includes such disorders as impotence (erectile dysfunction), low libido (sexual desire), poor timing of sexual
intercourse, failure to complete intercourse, and ejaculation abnormalities.
sexually transmitted disease (STD):
Infections that are most commonly spread through sexual intercourse or genital
contact.
|
|
Sickle Cell Anemia - An inherited blood disorder
caused by an abnormal form of hemoglobin - the oxygen-carrying molecule of the
red blood cells. Men with sickle cell anemia often show evidence of hypogonadism
(delayed sexual maturity), as well as slowed skeletal growth, small testes and
low sperm density. Hypogonadism usually is related to testicular malfunction as
well as hormonal imbalances (e.g., pituitary hormone and hypothalamic hormone
irregularities). Blood testosterone generally is low in men with sickle cell
disease, although luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels are variable and may be normal, low or even increased.
|
|
Sling Procedures - Patients with severe stress incontinence
and Intrinsic Sphincer Deficiency (Type III SUI or weakening of the urethra
muscle) may not be helped by simple suspension procedures. Yet such individuals
are good candidates for a sling procedure, which can create the urethral
compression necessary to achieve bladder control.
|
|
Smoking - Many IC patients feel that smoking worsens their symptoms.
(Because smoking is the major known cause of bladder cancer, one of the best
things a smoker can do for the bladder is to quit smoking.)
|
|
Sperm Retrieval - Sperm retrieval is not
limited to ejaculated semen. With today's technology, sperm can be obtained from
men with azoospermia (lack of sperm) that is caused by an obstructive lesion,
failed vasectomy reversal, inherited absence of the vas deferens, or other
uncorrectable blockage.
Sperm retrieval methods usually are scheduled to coincide with the female
partner's time of ovulation, so that they may be used for in vitro fertilization (IVF) of a retrieved egg. Sperm that is retrieved by MESA, PESA or TESE then can
be processed for use in procedures such as intracytoplasmic sperm injection (ICSI) (see also Intracytoplasmic Sperm Injection). While excess sperm from MESA
or PESA usually can be frozen for future use, most TESE-derived sperm are not of
sufficient quality or quantity for frozen storage (cryopreservation). Multiple
MESA or PESA procedures are not recommended, since repeated surgery can lead to
scarring around the site of incision.
|
|
Sperm Washing - Sperm washing is a
procedure that is used extensively for the treatment of semen with low sperm
counts, abnormal sperm forms, antibodies, and other fertility-impairing features
(see also Other Tests of Sperm Function). The "washing" is accomplished by
adding culture medium (a fluid containing nutrients and buffers) to the semen
and spinning the entire sample in a centrifuge (a machine that uses centrifugal
force to separate heavier and lighter elements in a solution). The heavy sperm
"pellet" is then rewashed in culture medium. If the physician needs a "rise" or
"swim-up" fraction of the most active sperm, the concentrated sperm sample is
incubated (kept warm) for about 1 hours, and the swimming sperm are extracted
from the top of the test tube. If the physician wants to enhance the fertile
potential of the sperm, TEST-yolk buffer (a special solution containing buffers,
chicken egg yolk, glucose and antibiotics) may be used during the washing and
pellet dilution procedures. The sperm that are gathered from such washing
methods are subsequently used for artificial insemination and in vitro
fertilization procedures.

sphincter:
A ring of muscle fibers located around an opening in the body that regulates the
passage of substances.

Staging this disease - Although grading
and the identification of cancer cell types can be helpful in determining a
patient's prognosis, most doctors believe that establishing the cancer's stage
gives a better indication of a patient's survivability.
Staging allows a physician to gauge the size and location of tumors by using
information gathered from such imaging studies as CT scans and MRIs, and
information from pathology tests and physical examinations. Once a stage has
been established, the physician can attempt to determine how a patient may do
over time and decide what type of treatment offers the best potential for
success.

STANDARD TRANSURETHRAL RESECTION OF THE PROSTATE (TURP) -Transurethral
resection of the prostate (TURP) has been the standard choice for the past 50
years of treatment for urinary symptoms attributed to a large prostate condition
commonly known as BPH that causes obstruction of the bladder outlet and voiding
symptoms such as urinary frequency, voiding at night and a slow urinary stream .
About 400,000 TURPs are performed each year in the United States. TURP is a
safe procedure with 80% of patients experiencing resolution of their voiding
symptoms and improvement of urinary flow measurements. A TURP involves the
removal of the obstructing portions of the prostate with a telescopic hot wire
loop that cuts like an electric knife. The TURP requires an anesthetic and takes
about 30-60 minutes to perform. A tube or catheter is inserted into the bladder
and is left in place for 2 to 3 days. The hospitalization lasts from 2-5 days
and requires two weeks of severe activity restrictions and another two weeks of
modest restrictions. The long term effectiveness of TURP in alleviating
obstruction and symptoms caused by BPH has made the TURP the gold standard to
which new procedures are compared.
However, the TURP is a surgical procedure with potential risks and
complications such as bleeding, impotence and incontinence. To decrease
hospitalization costs and recuperation time from work, alternative therapies are
being developed and introduced by the urologic community. These include medical
treatments and alternative surgical treatments that have the potential to
decrease complications and be as effective as the gold standard TURP.

stress test:
A diagnostic test that requires patients to lift something or perform an
exercise to determines if there is urine loss when stress is placed on bladder
muscles.
|
|
stress urinary incontinence:
Urinary Incontinence: The involuntary loss of urine during period of increased
abdominal pressure. Such events include laughing, sneezing, coughing or lifting
heavy objects.
|
|
Struvite Stones - Also known as "infection stones," struvite
stones account for up to 20% of all kidney stones. They are made up of
crystallized magnesium and ammonia, common byproducts of excessive acidity in
the urine caused by the bacterial breakdown of urea. This often occurs in
persons who experience infections of the urinary system. For this reason they
are most common in women, who suffer more urinary tract infections than men.
Struvite stones typically develop in a jagged or branch-shaped structure called
a "staghorn."
|
|
Super saturation - The most prevalent theory -- super
saturation crystallization -- holds that dehydration causes an imbalance in the
liquids and dissolved solids in the urine. The kidneys must maintain a proper
amount of water in the body as they remove harmful waste materials. If
dehydration occurs, the urine may become overloaded (supersaturated) with
substances that will not dissolve in water. These chemicals and trace elements
combine to form crystals which slowly build up, layer upon layer until a stone
is formed. Studies suggest that drinking plenty of water may prevent kidney
stones.
|
|
Surgery - This option is considered only if an IC patient has failed
all available treatments and the pain is severe. Most doctors are reluctant to
operate because the outcome is unpredictable in individual patients-some people
have surgery and still have symptoms.
Anyone considering surgery should discuss the potential risks and benefits,
side effects, and long- and short-term complications with a surgeon and family,
as well as with people who already have had the procedure. Surgery requires
anesthesia, hospitalization, and weeks or months of recovery, and as the
complexity of the procedure increases, so do the chances for complications and
failure.
To locate a surgeon experienced in performing specific procedures, check with
your doctor.
|
|
Systemic Chemotherapy - Many individuals with late-stage bladder tumor(s) and/or metastases have a poor prognosis. Therefore, researchers have
begun a number of clinical trials to test the effectiveness of systemic (in the
vein) chemotherapy with multiple drugs. In particular, combinations of agents
such as cisplatin, methotrexate, and vinblastine, with or without doxorubicin (CMV
or M-VAC), have produced some encouraging responses in late-stage patients. In
addition, the combination of cisplatin, cyclophosphamide, and doxorubicin (CISCA)
has shown some activity, although the responses have not been as great as those
reported for CMV or M-VAC treatments. In metastatic bladder cancer, other
chemotherapeutic agents that have produced some benefits are: paclitaxel, ifosfamide, gallium nitrate, and gemcitabine. Whenever possible, individuals
should be encouraged to participate in such trials. Multi-agent chemotherapeutic
trials for metastatic bladder cancer have produced response rates of up to 70%,
and survival times may be increased.
In persons with inoperable bladder cancer, the focus of care is palliation
(relief) of symptoms. Large, late-stage tumors may cause frequent, painful, and
bloody urination during the night and day. Decaying tissue within the tumor also
may be a constant source of infection. Therefore, urinary tract diversion in
such individuals may spare them the suffering and sleeplessness of persistent,
agonizing urination.
|
|
Systemic Illness - Not much is known about
the overall effects of illness on testicular function. Specific questions remain
about how diseases, metabolism and therapeutic drugs may affect reproductive
function. Yet fever alone has been shown to damage sperm. In humans, high
temperatures may kill or injure sperm cells after only a few hours. The
resultant decrease in sperm count often appears within 3 weeks after an episode
of high fever and can last for as long as 1 months. In addition, the
characteristics of the sperm itself may be changed, showing more abnormal shapes
and immature cells.

Tamoxifen - Tamoxifen, like clomiphene
citrate, is an oral anti-estrogen compound that has been used to treat male
infertility. But, unlike clomiphene, tamoxifen has no estrogenic activity.
Tamoxifen stimulates sperm output by increasing the release of gonadotropins. In
current studies, the most common oral dosage is 20 mg daily. As with clomiphene,
some men respond favorably to tamoxifen and show improved semen quality and
increased rates of conception; however, there are still questions regarding
which patient groups are most likely to be helped by tamoxifen therapy. Recent
findings suggest that pregnancy may occur in up to one-third of couples in whom
the male partner has received tamoxifen therapy.
|
|
Tamsulosin hydrochloride (Flomax) - Tamsulosin hydrochloride blocks only
the alpha-1a adrenergic receptors in the
prostate. Tamsulosin is used to treat the signs and symptoms of BPH;
however, because of its prostate-specificity, tamsulosin is not a recommended
treatment for hypertension. The usual oral dose of tamsulosin is 0.4-0.8 mg,
once daily.
|
|
Targis - The TargisTM System is an advanced form of
microwave therapy. It uses advanced microwave technology to deliver energy
through a flexible catheter. TargisTM therapy destroys the diseased tissue,
while protecting the pain-sensitive, healthy urethral tissue. The procedure is
anesthesia-free, with no need for IV sedation, spinal or general anesthesia.
Most patients can return home the same day as the treatment and quickly resume
everyday activities.
The catheter (also known as the Microwave Delivery
System) is inserted into the urethra. The balloon, located at the very end of
the catheter, is inflated to position the microwave antenna in the prostate.
Chilled water is circulated through the catheter to
protect healthy urethral tissue.
While the chilled water is being circulated, the
microwave power is started and the diseased tissue in the prostate is heated.
Heating is continued for one hour in order to destroy
the diseased tissue.
After one hour, the microwave energy is turned off,
while the chilled water continues to circulate to protect the healthy urethral
tissue from any residual heat.
At the completion of cooling, the procedure is finished
and the catheter is removed. |
|
TENS (Transcutaneous Electrical Nerve Stimulation) - With TENS, mild
electric pulses enter the body for minutes to hours two or more times a day
either through wires placed on the lower back or the suprapubic region, between
the navel and the pubic hair, or through special devices inserted into the
vagina in women or into the rectum in men. Although scientists don't know
exactly how it works, it has been suggested that the electric pulses may
increase blood flow to the bladder, strengthen pelvic muscles that help control
the bladder, and trigger the release of hormones that block pain.
TENS is relatively inexpensive and allows the patient to take an active part
in treatment. Within some guidelines, the patient decides when, how long, and at
what intensity TENS will be used. TENS has been most helpful in relieving pain
and decreasing frequency in IC patients who have Hunner's ulcers. Smokers do not
respond as well as nonsmokers. If TENS is going to help, change usually occurs
in 3 to 4 months.
|
|
Terazosin hydrochloride (Hytrin)
- Terazosin hydrochloride also blocks the alpha-1 adrenergic receptor sites in
the body. Like doxazosin, terazosin is prescribed for the treatment of urinary
outflow obstruction in BPH, as well as for hypertension. The typical dose is
1-10 mg, taken once daily.
|
|
Testicular Trauma Injury of the testes
may result in male infertility, especially if the trauma is followed by a
reduction in the size of the injured testicle and/or the detection of antisperm
antibody in the man's semen. It is believed that such infertility results not
from the wasting of testicular tissue, but rather from an immune reaction that
occurs due to penetration of the Sertoli cells' "blood-testis barrier" in the
testes.
|
|
Testicular Tumors - The rate of testicular
tumor is especially high among men with undescended testes. Therefore, hormone
therapy and/or orchiopexy (surgical placement of an undescended testis in the
scrotum) is advisable in most instances (see also Cryptorchidism). Even though
the increased risk of cancer remains after such treatment, the testes are more
easily examined for potential malignancies when they are in the scrotal
position.
|
|
Testosterone - Testosterone, an androgenic
(male) sex hormone required for sperm manufacture, has been employed as a form
of "rebound" therapy in men who suffer from inadequate sperm production. In
brief, testosterone - in the form of 200 mg testosterone cypionate or enanthate,
administered by weekly intramuscular injection for up to 12 weeks - is used to
stop sperm production and cause azoospermia (no sperm in the semen). When
testosterone is discontinued, sperm production may recover, or "rebound," and
lead to significantly increased sperm counts in a proportion of patients. Such
rebound usually occurs 4 to 6 months after stopping testosterone treatment.
Unfortunately, success rates from this therapy are poor, and some men run the
risk of permanent azoospermia after treatment.

testosterone:
The sex hormone that stimulates development of male sex characteristics and bone
and muscle growth; produced by the testicles and in small amounts by the
ovaries.

The Marshall Marchetti Krantz (MMK) procedure is still offered in many
medical centers throughout the United States, but it is no longer a favored
technique. This is because the sutures (stitches) in the procedure are placed
around the urethra, creating the potential for obstruction; in addition, the
surgical entryway limits the physician's ability to correct cystocele (herniation of the bladder into the vagina). During the MMK procedure, the
bladder neck and urethra are separated from the back surface of the pubic bone.
Sutures are placed on either side of the urethra and bladder neck, which are
then elevated to a higher position. The free ends of the sutures are anchored to
the surrounding cartilage and pubic bone.

|
Tolterodine Tartrate (Detrol) - Tolterodine tartrate is a
new drug that is classified as a muscarinic receptor antagonist: that is, it
blocks nerve receptors that respond to the chemical muscarine. Both bladder
contraction and salivation (formation of saliva) are controlled by muscarinic
receptors. By blocking muscarinic nerve receptors, tolterodine tartrate can
reduce symptoms of urinary frequency or urgency, and it is able to treat bladder
over activity and urge incontinence.
The typical dose of tolterodine tartrate is 1-2 mg, twice a day. Tolterodine
tartrate should not be used in people who are hypersensitive (have an
exaggerated reaction) to the drug or who have urinary retention, gastric
(stomach) retention, or uncontrolled narrow-angle glaucoma (eye disease
characterized by high pressure within the eye).

Transitional Cell Carcinoma - About 6% to 7% of kidney
cancers begin not in the kidney itself, but in the renal pelvis, the point where
the kidney joins the ureter (the tube running from the kidney to the bladder).
These tumors are called transitional cell carcinomas, and are made up of cancer
cells different from those that characterize RCC. Research indicates these
tumors are caused by cigarette smoking.
The symptoms of transitional cell carcinoma are quite similar to those of RCC,
and include hematuria and back or flank pain.
If found early, these cancers have a 90% cure rate. They may be treated in a
variety of ways, usually involving surgical removal of the kidney, ureter and
portion of the bladder connecting to the ureter. Depending on how much cancer is
present, chemotherapy and radiation may be used as adjuvent treatments. The
prognosis for cure declines sharply when the cancer invades the ureter wall or
penetrates the kidney.
Repeated follow-up examinations after surgery are important, as transitional
cell carcinoma is prone to recurrence.

TRANSURETHRAL ELECTROVAPORIZATION OF THE PROSTATE (TVP) - A new
modification on the TURP technology, termed transurethral electrovaporization of
the prostate, (TVP), applies electrical energy to electrosurgically vaporize or
remove the obstructive enlarged prostatic tissue. The technique involves the
application of a simple, specially designed grooved rollerball electrode that
allows the surgeon to channel open the urethra that is blocked by the prostate
tissue. Compared to the standard TURP, the procedure is safer and has minimal
side effects. There is less bleeding, shorter hospitalization and catheter times
and faster recovery period.
The procedure allows the grooved rollerbar electrode to rapidly heats the
tissue cells so that they turn into steam, leaving a space where the prostate
tissue was previously present. The majority of heat that is turned into steam is
then washed away by a constant flow of water. As the electrode moves to fresh
tissue, new cells are removed creating an incision or vaporized space. The
resulting pathway does not bleed because it is coagulated and sealed by the
electrically heated rolling action of the rollerball electrode. Technically,
this is a new way to do a TURP and TVP can also be utilized to perform a TUIP.
Our experience has demonstrated significant improvement in symptoms and urine
flow that parallel that reported for either conventional TURP and laser assisted prostatectomy. Anesthesia utilized included general, regional, and intravenous
sedation with local intraurethral xylocaine. Patients had their urethral
catheters removed within 24 hours after surgery and were able to void
spontaneously, unlike patients who were treated with TURP. There was minimal
blood loss during the surgery. Patients who reported adequate sexual erectile
function before surgery, reported no change in their sexual abilities after
surgery. There was no incidence of incontinence from sphincter damage.
Our current experience numbers over 170 patients with similar results to our
earlier published series. Long term data on its efficacy as well as multicenter
trials are currently underway to compare it to other procedures to treat BPH
such as the standard TURP and laser TURP. The major potential advantage of TVP
compared to the conventional TURP and laser assisted prostatectomy is cost, few
side effects, rapid convalescence time and short hospital stay overnight as well
as the simplicity of the procedure. This makes TVP or transurethral
electrovaporization a useful, safe and versatile tool in the treatment of the
enlarged prostate disease that cause urinary outflow obstruction or BPH.
Transurethral fulguration and resection of ulcers = Fulguration
involves burning Hunner's ulcers using electricity or a laser. When the area
heals, the dead tissue and the ulcer fall off, leaving new, healthy tissue
behind. Resection involves cutting around and removing the ulcers. Both
treatments, done under anesthesia, use special instruments inserted into the
bladder through a cystoscope. Laser surgery in the urinary tract should only be
done by doctors who have the special training and expertise needed to perform
the procedure.

TRANSURETHRAL INCISION OF THE PROSTATE (TUIP) -A transurethral
incision of the prostate (TUIP), is a simplified alternative to TURP that
simulates its results in both symptom relief and flow rates improvements. The
procedure is performed by making a simple deep cut or incision along the entire
length of the prostate to split it open. This allows the circular muscle fibers
running around the prostate to spring open and increase urinary flow by opening
the prostatic urinary channel. TUIP is ideally suited for smaller prostates and
has a lower incidence of ejaculation abnormalities. In appropriately selected
patients with relatively small and anatomically appropriate prostates, the
success rates for TUIP are similar to TURP with the advantage that hospital
stays and recovery are much shorter.

TRANSURETHRAL LASER VAPORIZATION / ABLATION OF THE PROSTATE (VLAP) -
The laser is a high energy source that has gained much attention as a unique
surgical tool in the surgical treatment of many diseases. In urology, the light
energy is converted to heat on contact to tissue to produce its surgical effect.
It is an energy modality utilized in breaking stones, treating bladder tumors
and removing prostate tissue.
With laser prostatectomy, a laser fiber is passed into the prostatic channel
under telescopic guidance. The laser is then used to destroy the obstructing
portions of the prostate by heating it up. The two techniques to remove tissue
are laser vaporization and laser ablation. With vaporization, high instantaneous
heat is created to vaporize or steam away prostate tissue. With ablation, a
lower laser energy is applied which heats up the tissue enough to dry it out,
and let it shrink and slough away with time. Compared to standard transurethral
resection or TURP, the advantages of these laser procedures are: no significant
bleeding, shorter hospitalization and reduced operating time. The laser albation
or VLAP has not been optimum in large prostate because of the necessity for
multiple treatments. Laser vaporization, on the other hand, has been able to
remove more tissue at one treatment. With these laser procedures, there has been
a greater amount of swelling around the prostate channel after the procedure
(3-10 days) which requires temporary catheter drainage (tube into the bladder to
drain urine). In addition, patients can experience a few weeks of urinary
frequency and irritation while the prostatic channel is healing. Its significant
advantages are no bleeding and a short hospital stay.
One concern of this procedure among the urological commiunity is that no
prostate tissue is removed. Therefore, one cannot be certain that cancer does
not exist. However, with the excellent diagnostic techniques available today
with PSA and Ultrasound, appropriate assessments can be performed and biopsies
taken if indicated.
Transurethral lithotripsy (trans=by way of, so via the
urethra) the stones are reached with a very slim tube-formed scope through the
urethra, bladder and ureter and cab be disintegrated with the use of a
oscillating probe. General anesthesia is necessary, because treatment can be
painful while it is of eminent importance that the patient and the stone does
not move.

TRANSURETHRAL NEEDLE ABLATION OF THE PROSTATE (TUNA) -Applying the
heat ablation principle to coagulate and necrose prostatic tissue, this
technique utilizes electrical radiofrequency current through small needles place
bilaterally into the prostate gland via a transurethral approach to induce
tissue destruction by local heating. This technique can be performed with
minimal anesthisia and as an outpatient procedure. Preliminary data on small
series of patients suggest it has potential a viable minimally invasive surgical
alternative for the treatment of BPH. This device is currently not FDA approved.

Transvaginal Slings - Precision Tack Transvaginal Anchor System is a
device that allows your physician to perform a minimally invasive procedure to
restore urinary function by returning your anatomy to its original position.
The transvaginal approach means no abdominal incision is made, therefore
eliminating any visible scars on the body surface. With Precision Tack two tiny
anchors are placed in the back side of the pubic bone to provide long-term
support of the bladder neck and urethra.
To begin with, your physician will make a small incision in the vaginal area.
This incision is necessary in order to create an area for a sling to be
inserted. The size and shape of the incision will be determined by your
physician, based on whether there is a need for additional repairs. Once the
incision is made your physician will place two small tacks in the pubic bone,
one on each side. These tacks provide a stable fixation for the bladder neck.
After the tacks are in place, your physician will insert a sling into the
vagina. A sling is a small piece of material that attaches to the tacks with
sutures. The sling will remain in the body providing support, like a hammock,
holding the anatomy in its original position.
With the tacks and sling in place, the vaginal incision is closed. The
Transvaginal Sling procedure is complete and normal urinary function should be
restored.
To help with the healing process, a catheter may be placed in your bladder.
It will be connected to a drainage bag, which will collect your urine. The
catheter will be removed within a short time. After the procedure is complete,
specialized nurses will monitor you. You will probably be discharged within 24
hours.
Routine physical activity may be restricted after the procedure. Strenuous
activity may be restricted for 8 12 weeks and physical activity for 6 8
weeks. Your doctor or nurse will provide you with specific guidelines.

Tricyclic Antidepressants (TCAs) - Tricyclic antidepressants
-- such as imipramine pamoate (Tofranil-PM) -- are often prescribed as part of
incontinence treatment programs, but they are not FDA-approved for incontinence.
Tricyclic antidepressants have anticholergenic effects. Many experts believe
that tricyclic antidepressants are beneficial because they decrease nighttime
incontinence and are useful for the management of
urge incontinence. The usual oral dose of imipramine is 10-25 mg, 1 to 3
times/day, for a total daily dose of 25-100 mg).
Other tricyclic antidepressants that potentially may be useful for
incontinence are: doxepin hydrochloride (Sinequan), desipramine hydrochloride (Norpramin), and nortryptyline hydrochloride (Pamelor).

|
TUIP - Your doctor may recommend transurethral
incision of the prostate (TUIP) if your prostate requires surgery, but isn't
greatly enlarged. This procedure widens the urethra by making several small cuts
in the neck of the bladder, the point where the urethra joins the bladder, and
in the prostate itself. This reduces the prostate's pressure on the urethra and
makes urination easier. Some experts believe TUIP gives relief with fewer side
effects than TURP, particularly a lower incidence of retrograde ejaculation.
However, others say its long-term benefits and risks have yet to be established
conclusively.

TUNA -Transurethral needle ablation of the prostate
(TUNA), procedure delivers low level radio frequency (RF) energy to the
prostate, relieving obstruction without causing damage to the urethra. A small
probe is inserted through the urethra and into the prostate. Two small
electrodes are deployed into the prostate and a low level of radio frequency
energy is applied. The energy heats the prostate tissue and shrinks it,
relieving the obstruction while protecting the urethra and surrounding areas.
The TUNA procedure can be performed in an office or hospital outpatient
center in less than 1 hour using minimal anesthesia. Clinical studies have
demonstrated that TUNA provides significant improvements in urine flow and other
symptoms of BPH. Its long-term side effects are minor compared with those of
such conventional procedures as TURP. Most patients are able to return to their
normal activities within 24 hours.

TURP - About 90% of all surgeries for BPH involve
transurethral resection of the prostate (TURP). This procedure requires no
external incision and takes about 90 minutes.
After giving anesthesia, the doctor inserts an instrument called a
resectoscope into the penis through the urethra. The resectoscope is about 12
inches long and half an inch in diameter. It contains a light, valves for
controlling irrigating fluid and an electrical loop to cut tissue and seal blood
vessels. The doctor uses this loop to remove the enlarged tissue one piece at a
time. The irrigating fluids carry this tissue to the bladder where they are
flushed out after the operation.
Patients usually must remain in the hospital for about 3 days after TURP
surgery, during which a catheter must be used to drain their urine. After that,
recovery usually is quick. Most men find their BPH symptoms improve rapidly and
are able to return to work within a month. During the recovery period, doctors
generally advise you to:
· Drink plenty of water to flush the bladder
· Eat a balanced diet and use a laxative if necessary to prevent
constipation and straining when moving the bowels
· Avoid heavy lifting, driving or operating machinery

electronic probe, inserted into the ureter under epidural (spinal) anesthesia,
to locate the stone. High-frequency ultrasound waves then are directed at the
stone to break it up gradually. The fragments can either be passed naturally by
the patient or removed by grasping forceps, basket extraction or suction through
the scope instrument. The instrument is not flexible, however, so ultrasonic
lithotripsy typically can be employed only when a straight path directly from
outside the body to the stone is possible.

Ultrasound - Ultrasound testing techniques use sound waves
projected into the body to produce a viewable image of internal organs,
structures and, in some cases, tumors. In this painless procedure, a jelly-like
lotion is applied to the patient's pelvic and kidney areas, and a small device
that emits ultrasonic pulses is slowly passed over the area. The sonic image
thus produced is viewed on a monitor.

underactive bladder:
A condition characterized by a bladder contraction of inadequate magnitude
and/or duration to effect bladder emptying in a normal timespan. This condition
can be caused by drugs, fecal impaction, and neurologic conditions such as
Diabetic neuropathy or low spinal cord injury or as a result of radical pelvic
surgery. It also can result from a weakening of the detrusor muscle from vitamin
B12 deficiency or idiopathic causes. Bladder underactivity may cause
overdistension of the bladder, resulting in overflow incontinence (see overflow
incontinence).

ureteroscopy:
A flexible, fiberoptic instrument resembling a long, thin telescope is inserted
through the urethra and bladder up to the ureter to visualize the tube. Often
used for retrieval of kidney stones.
|
|
Urethral Pressure Profile (UPP) - Many experts believe that
recordings of urethral pressures, or urethral pressure profiles (UPP), are of
limited value for the diagnosis of incontinence. This is because there is much
overlap between normal and abnormal urethral pressure values in patients with
incontinence.
UPP was one of the first diagnostic tests developed for urodynamic
measurement. A UPP catheter is placed in the patient's urethra, and static or
resting pressure values are recorded along the length of the patient's urethra.
Unfortunately, such resting values alone do not represent urethral function in
cases where incontinence is likely to occur.

Urethra - The tube that carries urine from the bladder and semen from
the prostate and other sex glands out through the tip of the
penis
|
|
Urethrolysis - Urethrolysis is an anti-incontinence operation that
involves the cutting of obstructive adhesions (fibrous tissue bands) that fix
the urethra to the pubic bone. Urethral obstruction is a well-recognized
complication of surgical procedures for disorders such as
stress incontinence. The symptoms of post surgical urethral obstruction
include urinary retention, incomplete bladder emptying, irritation or pain when
urinating, decreased force of the urine stream, hesitancy, and recurrent urinary
tract infections.
Urethrolysis that is performed via an incision through the vagina (female
reproductive canal) is known as transvaginal urethrolysis. Transvaginal
urethrolysis is associated with fewer complications than other methods of urethrolysis, and it permits the correction of coexisting vaginal abnormalities.
Transvaginal urethrolysis is the most effective procedure to mend urethral
obstruction after surgical repair of stress incontinence.

Uric Acid Stones - Uric acid is a normal byproduct made by
the body as it breaks down protein. It is normally flushed out by the kidneys in
urine. However, some people, particularly men, build up excessive uric acid
concentrations in their kidneys or joints. In the joints, this can lead to gout,
an inherited disorder of uric acid metabolism with painful arthritic symptoms.
If this buildup occurs in the kidneys as well, it often results in the formation
of uric acid stones.
An estimated 5% to 13% of patients with kidney stone disease, particularly
men, develop uric acid stones. Genetics may play a role in uric acid stone
propensity: Persons of Mediterranean descent, particularly those of Portuguese
extraction, appear to have high incidences of uric acid stones, while those of
Anglo-Saxon descent seem to be less at risk. Patients prone to developing uric
acid stones typically are advised to reduce their consumption of high-protein
foods, especially meat.

Urinalysis - Urinalysis is a test in which a urine sample is
analyzed in the laboratory for signs of infection, blood, urinary stones or
other abnormalities. A clean-catch (midstream) or catheterized urine sample
should be obtained for this study. Sometimes a urine culture is performed to
determine the type of infectious organisms that may be present in the urinary
tract. urinary tract infection (UTI) is defined as a urine sample that contains
bacteria in the amount of 105 CFU/ml or more. If blood, glucose (sugar), or
protein are also present in the urine sample, further testing is indicated.

urinary incontinence:(UI)
Involuntary loss of urine sufficient to be a problem. There are several types of Ul, but all are characterized by an inability to restrain voiding.
|
|
Urinary Tract Diversion - Until recently, most bladder cancer patients
who underwent cystectomy (bladder removal) needed an ostomy (surgical creation
of an artificial opening) and an external bag to collect their urine. Now,
reconstructive surgical methods have been developed to replace the cancerous
bladder. The continent urinary reservoir is the newest form of
urinary diversion. With this technique, a piece of colon (large intestine)
is removed and used to form an internal pouch to store urine. The pouch is
specially refashioned to prevent back-up of urine into the ureters (one of two
tubes that pass urine out of the kidneys and into the bladder) and kidneys. The
patientwhether male or femalecan urinate as before, without the need for an
external bag or collection device. The urinary reservoir procedure is associated
with some complications, such as bowel (intestine) obstruction, blood clots,
pneumonia (lung inflammation), ureteral reflux (back-flow), and ureteral
blockage.

urinary tract infections (UTIs):
UTIs are caused by bacteria that invade the urinary system and multiply, leading

urodynamic tests:
Diagnostic tests to examine the bladder and urethral sphincter function.
|
|
Urodynamics - Urodynamic studies are conducted to measure
pressure in the bladder and to evaluate the flow of urine. Urodynamic studies
are particularly useful for the diagnosis and confirmation of intrinsic
sphincter deficiency and uncertain cases with
mixed incontinence,
overflow,
urgency or total incontinence.
|
|
Uroflow - Usually performed in your doctor's office,
the uroflow test determines how quickly and completely you can empty your
bladder. With a full bladder, you will be asked to urinate into a special
measuring device. A reduced flow may indicate BPH.
|
|
Uroflowmetry - Uroflowmetry is a simple test that is not by
itself diagnostic, but often is performed along with cystometry. The patient
drinks fluids until the bladder is full. He or she then is asked to cough or
strain while sitting in a flow chair (a special chair used to measure urine).
The voided urine is measured, and volume of urine left in the bladder is
calculated by sonography (ultrasound waves used to get an image of the bladder)
or catheterization. Other variables, such as voiding time and urine flow rates,
are also determined.
stress or
urge incontinence patients usually have a normal or increased urinary flow
rate unless there is an obstruction in the urinary tract, in which case the flow
rate is decreased. Urinary flow rates increase throughout childhood and reach
their highest level in young adults.

Vaportrode - Transurethral vaporization of the
prostate (TUVP), also known as vaportrode, is a new technique that involves
direct application of high heat (less than 100 degrees) to the prostate tissue
by means of a grooved roller-bar that vaporizes tissue instead of burning it
with a laser. The immediate tissue loss leads to quick improvement in BPH
symptoms and urinary flow, comparable to TURP. The procedure takes from 20 to 65
minutes. Most patients can have their catheters removed within 24 hours and can
go home on the second day after treatment.

Varicocele -
Varicocele - varicose veins of the scrotal venous system that drains the
testicles - is a common abnormality found in roughly one-third of all men who
are being evaluated for infertility. And, although not all men with varicoceles
are infertile, a significant number of infertile men will have a varicocele.
Varicocele is caused by a back-flow and pooling of blood due to malfunctioning
or missing valves in the spermatic veins. Because of the long, top-to-bottom
route of the internal spermatic vein (ISV) on the left side of each testis, over
90% of varicoceles occur on the left; therefore, a right-sided varicocele may
indicate the presence of another disorder, such as a venous blood clot or tumor.

Varicocele Embolization - Varicocele
embolization is an alternative to surgery for men with varicocele. Embolization
is an outpatient procedure in which the varicocele is closed off (occluded) by
means of a balloon catheter (flexible tube with a tiny detachable balloon),
steel coil, and/or sclerosing (vessel-hardening) solution.
First, the patient is catheterized (a flexible tube is inserted into a blood
vessel) at a few venous sites (e.g., right femoral vein, left renal vein, left
internal spermatic vein). The patient then performs a Valsalva maneuver (a
forced "exhale" with a closed nose and mouth) and undergoes venography (X-ray of
a vein filled with contrast medium) to identify the location of the varicocele.
Next, the balloon catheter is drawn through the vessel and usually is inflated
at the level of the pubic ramus (e.g., pubic branch of the internal spermatic
vein), below the insertion of most collateral (parallel) veins. Careful
attention is paid to the level of occlusion to avoid varicocele recurrence. If
follow-up venography shows that residual collateral veins remain, further
occlusion may be performed by using a steel coil or another balloon with or
without a sclerosing agent such as glucose. After the catheter materials are
withdrawn and no venous bleeding is observed, the patient is sent home to resume
normal activities the next day.
Since venography is used to visualize and "target" the veins during embolization, varicocele theoretically should not recur in most men, but there
is still a high rate of technical failure and/or recurrence. On very rare
occasions, balloons have moved from the scrotal venous system into the general
circulation and caused embolism (clots) in the lung and other sites.
|
|
Varicocelectomy - Varicocelectomy - the
cutting away of a varicocele - is usually performed with regional or general
anesthesia. The surgeon makes an incision into the groin, and the problematic
venous system then is repaired. The venous channels are divided to prevent
varicocele recurrence, and the external cremasteric vessels (the veins
associated with the testis-elevating muscle) also are tied off and divided.
Varicocele repair often dramatically increases semen quality and pregnancy rates
in infertile couples. The major complications of varicocelectomy are varicocele
recurrence and formation of hydrocele (collection of fluid in a contained area).
However, newer microsurgical techniques have substantially limited these
complications.

Vasoepididymostomy - Vasoepididymostomoy
is a microsurgical procedure that uses a microscopic camera and very small
operative tools to correct obstructions in the genital tract (see also Vasography). The procedure requires removal of the blockage in the epididymis
(the coiled tube that extends the length of each testis and connects with a
larger duct - the vas deferens) and re-attachment of the epididymis to the vas
deferens. Vasoepididymostomy may improve pregnancy rates by up to one-third of
all patients; however, the success of vasoepididymostomy is dependent upon the
experience and technical expertise of the microsurgeon.
Classic signs of epididymal "blockage" are a swollen top of the epididymis,
the presence of sperm in semen drawn from the obstructed segment, and otherwise
normal testes. Blockages frequently arise in the epididymis because of
inflammation due to sexually transmitted diseases (STDs). Gonorrhea is an STD
that, if left untreated, is likely to damage the epididymis and produce
obstruction. Other, rarer causes of obstruction include cysts, inherited atresia (tubal closure), and genital tuberculosis. Vasectomy (a contraceptive procedure
involving surgical removal of a portion of the vas deferens) currently is the
leading cause of infertility secondary to genital tract obstruction (see also Vasovasostomy). There is an increased likelihood of epididymal blockage among
men who have had vasectomies of more than 10 years' duration.
|
|
Vasography - is an X-ray study in which dye is
injected into the vas deferens. The procedure usually is conducted under general
anesthesia. A small vertical cut is made over the testis, which is then pulled
forward. (Note: If the patient has a history of inguinal [groin] hernia repair,
the cut may be made directly over the scar from the previous surgery; sometimes
the obstructed site of the vas is clearly found at this site and vasography is
not even necessary.) The vas deferens is identified and, using an operating
microscope and microsurgical tools, the cavity (lumen) of the vas is inspected
for the presence of sperm-containing fluid. If no fluid is present, a catheter
(flexible tube used to withdraw fluid) is passed through the vas to the epididymis, which is "milked" for fluid. If there is still no fluid, the seminal
vesicle end of the vas is filled with a salt water and/or dye solution to
confirm that this region is free from obstruction.
|
|
Vasovasostomy - Vasovasostomy, otherwise
known as vasectomy reversal, is the re-connection of the severed ends of the vas
deferens. This procedure, like vasoepididymostomy, commonly is conducted using
microsurgical methods. However, nonmicroscopic, "macrosurgical" techniques also
are successfully employed. Most vasectomy reversal procedures are conducted on
an outpatient basis.
During microsurgical vasovasostomy, most surgeons use a "two-layer" technique
in which both the inside and outside layers of the severed tubules are
reconnected with tiny sutures. Close attention is paid to the character of the
fluid that is obtained from the testicular end of the vas: if the fluid is clear
and colorless and if sperm are present, the results of vasovasostomy usually are
favorable. By contrast, if the fluid is thick or creamy and if sperm are absent,
a vasoepididymostomy usually is performed rather than a vasovasostomy (see also Vasoepididymostomy).
The complications experienced after vasovasostomy are infrequent and minor.
After vasovasostomy some men are found to produce antisperm antibodies - immune
system molecules that lessen the fertilizing potential of sperm (see also Other
Sperm Function Tests). The antibody production is a result of the vasectomy.
Some physicians recommend the collection and freezing of sperm from the site of
vasectomy reversal in the event that sperm are abnormal or sperm output is
inadequate after successful reconnection of the vas.
The new forms of fertility treatment - collectively known as Assisted
Reproductive Technologies (ART) - incorporate many methods of sperm retrieval
and preparation. Once the sperm have been processed to ensure optimal
fertilizing potential, they are used in a variety of procedures that aid the
process of conception. These procedures include artificial insemination (AI), in
vitro fertilization (IVF), and sperm microinjection techniques.

vesica sling procedure: is a surgical sling procedure used to stabilize the
bladder neck and provide support for the urethra using autologous or synthetic
sling material. This procedure treats both hypermobility and ISD.
Vesica® sling procedure, a minimally invasive (reduced operative risk
and a shorter recovery phase) surgery, involves the placement of a sling to
support the bladder neck, urethra and sphincter.
Through the opening created by the incision(s), your surgeon will place two
small anchors into the pubic bone in order to provide stable fixation for the
bladder neck. He/she will then take one end of the suture and guide it through
the tissue on one side of the bladder neck then the other side.
Depending on your diagnosis your physician may elect to use a sling made of
either a biocompatible synthetic material or of your own tissue. This sling
(like a hammock) is secured to the anchor placed in the bone and serves as
additional support for the urethra, bladder neck and sphincter.
To help with the healing process, a catheter may be placed into your bladder.
The catheter will be connected to a drainage bag, which will collect your urine.
Routine physical activity may be restricted for a short time after the
procedure and strenuous activity for 8-12 weeks. Your doctor or nurse will
provide you with specific guidelines.

Voiding Diary - A voiding diary is a record of urinary
habits over a 24-hour period. It can help your physician to determine the exact
nature and severity of your bladder control problem. Some of the information
gathered from a voiding diary may include:
· Frequency of urination
· Time-of-day occurrence of urination
· Total voided volume
· Average voided volume
· Largest single volume
· Type and severity of incontinence episodes

Water-Induced Thermotherapy (WIT) - Water-induced
thermotherapy (WIT) is the most recent development in the treatment of noncancerous, enlarged prostate. This innovative procedure was developed during
the 1990s and received FDA approval in 1999. WIT is a minimally invasive
outpatient procedure that is less complicated than other treatments for BPH.
WIT effectively destroys excess prostatic tissue, which presses on the
urethra and compromises urinary flow, and thus reopens the urethra. WIT has its
advantages: it can be performed in ambulatory surgery, outpatient surgery, or a
physician's office; it takes only 45 minutes and does not require general
anesthesia, and therefore does not carry the risks associated with inpatient
surgery; and it does not produce incontinence or impotence, common effects of
surgical treatments for BPH.

Wilms' Tumor - A relatively rare form of kidney cancer, Wilms' tumor (also known as nephroblastoma) accounts for about 5% to 8% of
kidney tumors in children. It occurs in about 7 out of every 1 million children
around the world per year, regardless of race, and is thought to be caused by
genetic mutation that causes abnormal growth within the tubules of the kidney nephrons. The disease occurs equally in boys and girls. It typically first
appears in children between 2 and 5 years of age, but has been known to occur
rarely in adolescents as old as 15.
Wilms' tumor can arise anywhere within the kidney's tissues. Untreated, it
can spread, invading veins, lymph nodes, the adrenal glands, large or small
bowel and liver. Fortunately, advances over the past few decades in radiation
and chemotherapy, pediatric anesthesia and surgery have made Wilms' tumor one of
the most curable of all childhood cancers. Today the five-year survival rate
approaches 90%.

XX Disorder - Otherwise known as sex
reversal syndrome -- a variant form of Klinefelter's syndrome. Although affected
men have a normal number of chromosomes (46), the sex chromosome signature is
"XX," with a displacement of the Y chromosome somewhere within the other pairs
of somatic (bodily) genes. The signs of XX disorder are comparable to those of
Klinefelter's syndrome, yet most individuals are short in stature are less
likely to be mentally deficient, and may exhibit hypospadias (underside opening
of the urethra in the glands penis).
|
|
XYY Syndrome - XYY syndrome has more a
variable physical expression than other genetic abnormalities. Indeed, no
consistent syndrome has yet been defined, since XYY men may suffer from
abnormalities like seminiferous tubule sclerosis, or they may present with
normal gonads. In general, though, men with XYY syndrome are extremely tall, and
they may suffer from a pustular form of acne. Some individuals express
antisocial behavior. Ejaculate samples from XYY men vary between azoospermia (no
sperm) and normal sperm counts. Blood and urinary levels of testosterone,
luteinizing hormone (LH), and follicle-stimulating hormone (FSH) often are
normal; abnormalities in these hormone levels are related to the extent of germ
cell damage within the testes.
