Surgery Overview
An artificial sphincter is a device made of silicone rubber that is used to treat urinary incontinence.
An artificial sphincter has an inflatable cuff that fits around the urethra close to the point where it joins the bladder. A balloon regulates the pressure of the cuff, and a bulb controls inflation and deflation of the cuff. The balloon is surgically placed within the pelvic area, and the control pump is placed in the scrotum.
The cuff is inflated to keep urine from leaking. When urination is desired, the cuff is deflated, allowing urine to drain out.
What To Expect After Surgery
Because these procedures involve abdominal surgery, hospitalization is required.
You will most likely be able to leave the hospital the day after having the surgery.
Why It Is Done
Installation of an artificial sphincter may be done for:
- Urinary incontinence caused by the removal of the prostate.
- Severe continual leakage of urine from the urethra.
- Severe urinary incontinence for which other methods of treatment have failed.
How Well It Works
Artificial sphincter placement is the most reliable treatment for men who have incontinence after prostate removal for cancer.1
In cases of severe stress incontinence and persistent leakage, implantation of an artificial sphincter has been successful in relieving incontinence in up to 90% of men.2
Risks
Complications with this type of surgery include needing another surgery, or revision, in 27% of cases, in which 5% reported erosion of the part of the urethra surrounded by the artificial sphincter and 3% developed infections.1
What To Think About
Because complications may occur, this is a treatment method that generally is reserved for people for whom all other treatment options have failed. Some people may prefer to manage their symptoms with absorbent pads and changes in habits rather than have this surgery.
