Sphincters are muscles that allow your body to hold in urine. An inflatable artificial (human-made) sphincter is a medical device that keeps urine from leaking when your urinary sphincter no longer works well. When you need to urinate, the cuff of the artificial sphincter can be relaxed so urine can flow out.
Other surgeries to treat urine leakage and incontinence include:
Artificial sphincter (AUS) - urinary
You will have either general anesthesia or spinal anesthesia before the procedure. With general anesthesia, you will be asleep and will not feel pain. With spinal anesthesia, you will be awake but numb from the waist down, and you will not feel pain.
An artificial sphincter has three parts:
A surgical cut will be made in one of these areas so that the cuff can be put in place:
Once the artificial sphincter is in place, you will use the pump to empty (deflate) the cuff. Squeezing the pump moves fluid from the cuff to the balloon. When the cuff is empty, your urethra opens so that you can urinate. The cuff will re-inflate on its own in 90 seconds.
Artificial sphincter surgery is done to treat stress incontinence, a leakage of urine that occurs with activities such as walking, lifting, exercising, or even coughing or sneezing.
The procedure is recommended for men who have urine leakage after prostate surgery.
Women who have urine leakage usually try other treatment options before having an artificial sphincter placed.
Most of the time, your doctor will recommend drugs and bladder retraining before surgery.
This procedure is generally safe. Ask your doctor about these possible complications.
Risks for any surgery are:
Risks for this surgery may include:
Always tell your doctor or nurse what drugs you are taking, including over-the-counter medications, herbs and supplements that you buy without a prescription.
During the days before the surgery:
On the day of your surgery:
Your doctor will test your urine to make sure you do not have a urinary infection before starting your surgery.
You may return from surgery with a catheter in place. This catheter will drain urine from your bladder for a little while. It will be removed before you leave the hospital.
You will not use the artificial sphincter for a while after surgery. This means you will still have urine leakage. Your body tissues need this time to heal.
About 6 weeks after surgery, you will be taught how to use your pump to inflate your artificial sphincter.
You will need to carry a wallet card or wear medical identification that tells health care providers you have an artificial sphincter. The artificial sphincter must be turned off if you need to have a urinary catheter placed.
Women may need to change how they do some activities (such as bicycle riding), since the pump is placed in the labia.
Urinary leakage decreases for many people who have this procedure, but you may still have some leakage. Over time, some or all of the leakage may come back.
There may be a slow wearing away of the urethra tissue under the cuff. This tissue may become spongy. This may make the device less effective. If your incontinence comes back, changes may be made to the device to correct it.
