The artificial urinary sphincter (AUS) is an implantable device used to treat stress incontinence, mostly in men. The device is made of 2 or 3 parts: The pump, cuff, and balloon reservoir, connected to each other by specialized tubes. The cuff wraps around the urethra and closes it. When the person wants to urinate, he presses the pump (implanted in the scrotum), to deflate the cuff, and allow the urine to pass. The cuff regains pressure within a few minutes to regain continence. The European Association of Urology considers the AUS as the gold standard in surgical management of stress urinary incontinence in men after prostatectomy.
