What Is an Artificial Urinary Sphincter?
An artificial urinary sphincter (AUS) is an implanted device used to treat stress urinary incontinence, particularly in men who continue to experience leakage following prostate treatment. The device helps keep the urethra closed until you are ready to urinate. To urinate, you manually open the device by pressing a hidden button in the scrotum.
The device has three main components and is hidden entirely inside the body with no external parts. A fluid-filled cuff fits around the urethra, while a small pump is placed in the scrotum and a pressure-regulating balloon is positioned internally. When it is time to urinate, the patient squeezes the pump to release pressure from the cuff so urine can pass. Afterward, the cuff refills on its own and closes around the urethra again.
