Urinary Sphincter Replacement

Medically reviewed by Last updated on Jun 5, 2024.

Urinary sphincter replacement is surgery to replace your urinary sphincter with an artificial urinary sphincter (AUS). The urinary sphincter is a muscle that surrounds your urethra. The sphincter squeezes the urethra to keep urine in the bladder until it is time to urinate. An AUS device has a balloon reservoir, a cuff, and a pump. When the AUS is turned on, liquid inside the balloon flows into the cuff. When the cuff is filled, it squeezes your urethra to prevent urine from leaking out of your bladder. To urinate, you press the pump. This relaxes the cuff and allows urine to flow out of your bladder.
