A suprapubic catheter is a thin tube that drains urine from your bladder. The tube is put into your bladder through a small cut in your lower belly. The urine collects in a bag attached to the tube. The bag is usually attached to your leg. Sometimes the catheter tube has a valve that lets you drain the urine into the toilet or other container.
You may need a suprapubic catheter if you have nerve damage, a problem with your urinary tract, or a disease that weakens your muscles.
Having a catheter for a long time increases the risk of getting a urinary tract infection. So catheter care focuses on preventing infection.
How can you care for yourself when using the catheter?
- Wash your hands before you handle the catheter.
- Clean the area around the catheter with soap and water daily.
- Keep the drainage bag lower than your bladder to keep urine from backing up.
- Clean the bag every day after removing it from the catheter. Use another container while you clean the bag. To clean the bag, fill it with 2 parts vinegar to 3 parts water and let it stand for 20 minutes. Then empty it out, and let it air dry.
- Empty the drainage bag when it is full or at least every 8 hours.
Clean the area around the catheter with soap and water daily.
How do you empty the catheter bag?
If your doctor has asked you to keep a record, write down the amount of urine in the bag before you empty it.
Wash your hands before and after you touch the bag.
- Remove the drain spout from its sleeve at the bottom of the drainage bag.
- Open the valve on the drain spout. Let the urine flow out into the toilet or a container. Be careful not to let the tubing or drain spout touch anything.
- After you empty the bag, close the valve. Then put the drain spout back into its sleeve at the bottom of the collection bag.
How do you replace the catheter?
Your catheter may have to be replaced every 4 to 6 weeks. A caregiver may do this for you.
You may be given a catheter kit that has the supplies you need. If you have not received a kit, ask your doctor what you'll need. Some of the things you'll need include a new catheter, syringes, sterile fluid, gloves, skin cleaning supplies, and lubricant.
Here are general instructions for replacing the catheter. Your doctor, nurse, or home health care worker may give you more specific instructions.
Removing the catheter
- Wash your hands with soap and water, and put on gloves.
- Fill a syringe with the fluid provided in the catheter kit.
- If there is a dressing on the insertion site, remove it. Clean the area around the catheter with the supplies from the catheter kit.
- Use another syringe to take out the water from the catheter balloon.
- Hold the catheter close to where it goes into your belly. Gently pull the catheter up and away from you until it comes out.
Putting a new catheter in
Don't wait to put in the new catheter. If you wait, the opening can close.
- Wash your hands and put on a new pair of sterile gloves.
- Lubricate the catheter tip and push it through the opening in your belly. Push it in as far as the other catheter was placed.
- When the catheter is in place, urine should begin to flow through it. This may take a few minutes.
- Inflate the balloon using the first syringe, which you filled with fluid from the kit.
When should you call for help?
Call your doctor now or seek immediate medical care if:
- Your catheter becomes blocked and urine does not collect in the drainage bag.
- Your catheter leaks.
- You have blood or pus in your urine.
- You have pain in your back just below your rib cage. This is called flank pain.
- You have a fever, chills, or body aches.
- You have groin or belly pain.
- Your urine is cloudy or smells bad.
- You have pain, increasing redness, or bleeding around the catheter.
- You have swelling around the catheter or in your belly.
Watch closely for changes in your health, and be sure to contact your doctor if you have any problems.
