Urinary incontinence is the loss of the ability to control urination. Urinary incontinence sometimes occurs in men who have had surgery for prostate cancer.
What is the prostate's role in urination?
When urine is emptied into the bladder from the kidneys, it is kept inside the body by a couple of valves that stay closed until your body “tells” them to open when you urinate.
Complete removal of the prostate through surgery (radical prostatectomy) can cause urine to leak because one of the valves is removed. Approximately six to eight percent of men who have had surgery to remove their prostate will develop urinary incontinence.
Fortunately, there are ways to treat incontinence caused by prostate surgery. For instance, there are medications or behavioral techniques and exercises, including Kegel exercises and biofeedback, that teach men to hold urine.
These methods help men who have mild to moderate leakage. Men who have more severe leakage problems may need another surgery.
There are two types of surgery for urinary incontinence: the urethral sling and the artificial urinary sphincter. Usually, the incontinence needs to last for at least one year after the prostatectomy before the man is considered for one of these surgeries.
In the urethral sling procedure, a synthetic (man-made) mesh tape is placed around part of the urethra (the tube through which urine passes out of the body). This gently and slightly moves the urethra into a new position. This is a minimally invasive procedure, which means that the surgeon only has to make a small incision (cut) in the perineum (the space between the base of the scrotum and the anus).
A urethral sling procedure is best suited for men who have mild to moderate urinary incontinence after a radical prostatectomy that is not improved with more conservative measures. It is highly successful in helping patients overcome incontinence, or reduce episodes of leaking urine.
Before the surgery, the doctor may do some tests, including the following:
- A urodynamic study, to test how well the urinary tract is working;
- A 24-hour pad test (to identify how many pads the man uses and how much urine he leaks);
- A cystoscopy, a test in which the doctor looks inside the bladder with an instrument called a cytoscope.
The patient does not have to donate any of his own blood before surgery.
What are the risks and complications of the urethral sling procedure?
The main risks of the urethral sling procedure include a temporary inability to urinate, or the possibility that urinary leakage will happen again later.
Complications are rare, and may include bleeding and infection (of the mesh or the bone area or pubic bone), erosion, inability to urinate (very rare), or continuing leakage.
What happens after urethral sling surgery?
Patients usually recover from this surgery quickly. It's best to limit demanding activities for approximately six weeks after surgery to avoid having the sling come down before healing is complete.
After surgery, there may be swelling that makes it difficult to urinate. The patient may have a catheter (a hollow tube) coming out of the urethra for a short period of time to allow him to empty his bladder.
After the swelling goes down, the patient will gradually be able to urinate on his own and empty his bladder well. However, the normal urination pattern may not return for a few weeks.
Some patients who have had this procedure have been cured of their urinary incontinence; others have improved to the point where they don't use as many pads.
Artificial urinary sphincter
An artificial urinary sphincter (AUS) can help patients who have moderate to severe urinary incontinence because they have had significant sphincter muscle or valve damage after prostate cancer surgery.
The AUS has three parts:
- an inflatable cuff that is placed around the upper urethra. The cuff closes off the urethra to prevent leakage of urine.
- a pump that is inserted into the scrotum. The pump controls the opening and closing of the cuff.
- a small pressure-regulating balloon (about the size of a Ping-Pong ball) that is placed in the abdomen, under the muscles. The balloon maintains fluid under pressure within the urethral cuff to hold urine back.
When the patient feels the need to urinate, he presses on the pump, which opens the cuff to allow urination. Once the patient is done urinating, the cuff automatically closes again.
The AUS procedure is successful in 90% of cases. Risks are uncommon and include:
- Failure of the device (usually because of a fluid leak)
- Erosion of the device into the urethra
All of these would require additional surgery.
