Catheterization is removing urine from the bladder by placing a tube in the bladder. This is done when the bladder does not empty on its own, when a bladder leaks urine, or when very high pressures have developed in the bladder. It is important to prevent a urinary tract infection. Extra urine in the bladder can grow germs. Over time, chronic infections and high bladder pressures can damage the kidneys.
Self catheterization is not difficult. You cannot hurt the bladder if you follow directions. Almost anyone can learn the technique, even a 7- or 8-year-old child.
Show All- Bladder
- A muscular sac that holds urine until it is emptied from the body.
- Bladder overdistention
- A bladder filled beyond normal capacity.
- Catheter
- A tube used for emptying urine from the bladder.
- Foreskin
- A fold of skin covering the tip of the penis.
- Lubricant
- A water soluble, jelly-like substance used to prevent irritation. (Do not use a petroleum-based product, such as Vaseline". Use a product such as K-Y" Jelly, which will not damage the catheter).
- Sphincter muscle
- A circular muscle constricting an opening (in this case, the bladder).
- Urethra
- The tube inside the body that carries urine from the bladder to the outside of the body.
- Void
- To urinate; to empty the bladder.
Urine is liquid waste that is made in the kidneys through a blood filtering process. Urine passes from the kidneys, down through the ureters and into the bladder. The bladder is an elastic muscle that acts like a storage tank. As the bladder fills, its walls relax to hold more urine and the sphincter muscle remains tight to prevent leakage of urine.
Assemble these supplies after washing your hands.
- Lubricant -- K-Y" Jelly or Lubifax"
- Paper towel
- Catheter
- Sterile cup (if a specimen is needed)
- Soap and water (a mild soap, such as Liquid Ivory"), Betadine Swabsticks or Benzalkonium chloride wipes
- Urinal, other container or diaper to drain urine into if not using the toilet
- Wash your hands using soap and water.
- Arrange your clothing so it's not in your way.
- If you're uncircumcised, pull back your penis' foreskin and keep it back throughout the catheterization. Wash the end of your penis thoroughly with soap and water, Betadine or Benzalkonium wipe.
- Squeeze some lubricant onto the paper towel and lubricate the first 4-5 inches of the catheter.
- Hold your penis at a right angle to your body. Grasp the catheter as you would a pencil or dart and slowly insert it 7-10 inches, until urine begins to flow. Then, gently push the catheter an inch farther.
- Allow all urine to drain into the toilet or container.
- When urine stops draining, slowly remove the catheter. Wash your hands.
- Note the appearance and amount of urine. If something unusual happens (see symptoms below), report it to your child's doctor.
- To clean catheters, follow the instructions given by your doctor or nurse.
- Cloudy or dark urine
- Blood in urine
- Nausea or vomiting
- Chills or fever
- Flank pain
- Lethargy
- Frequency of urination
- Urgency
- Painful urination
- Swelling or redness around urethral opening
- Change in smell of urine
- Noticeable decrease in the amount of urine
- Unusual discharge from urethra or around catheter
It is very important that you catheterize yourself on time, every time, and that you do not skip it. Evenly space catheterizing times from morning to night. Drink a lot of liquids to improve the flow of urine through the kidneys.
