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.
