Never stop self-catheterization unless instructed by your physician.

The following may be an indication that it is time to catheterize:

Distended bladder
Feeling of fullness
Restlessness
Perspiration
Chills
Headache

How to clean your catheter:
Always wash hands before and after procedure.

Wash catheter after use in warm soapy water.

Run tap water through the catheter. Place the catheter on a paper towel to air dry.

Alternating catheters is a good idea.

Replace your catheter in a clean container.

Catheters should be discarded when they begin to lose their flexibility, or become brittle or discolored.

An option to cleaning your catheter is to soak it in a solution of 1 part vinegar to 3 parts tap water once each week to keep urine crystals from forming inside the catheter.

Equipment
1.  Catheter -- #14 French or the size specified by your physician.
2.  A container to carry the catheter.
3.  Cotton balls moistened with soap and water.
4.  Water soluble lubricant

DO NOT USE MINERAL OIL OR PETROLEUM LUBRICANT.

Procedure
1.  Prepare equipment.
2.  Wash hands with soap and water.
3.  Urinate if you can.
4.  Stand, sit or lie down, whichever is easier for you.
5.  Hold penis up with one hand and cleanse the tip with a cotton ball moistened with soap and water. Wash in a circular motion starting at the urethra and working outward.
6.  Lubricate the catheter end that will be going into the urethra. Lubricant must be water-soluble.
7.  Holding the penis upward, gently insert the catheter through the external meatus.
8.  Once you have passed one half length of the catheter through external meatus, lower the penis and slide the catheter the rest of the way into the bladder until urine flows.
9.  Allow the bladder to empty completely.
10. To remove the catheter, slowly rotate it as you withdraw it. Stop each time more urine drains.
11. To completely remove the catheter pinch off the end and pull it out. This will prevent urine from flowing back into the bladder.
12. Check for any unusual odor and/or cloudy hazy urine. Be aware of any changes you may need to report to your doctor.

People with spinal cord injuries should call their doctor if they have a severe pounding headache (this may indicate unresolved autonomic dysreflexia) and immediately catheterize themselves to empty their bladder.
