Artificial urinary sphincter. Coloured frontal X- ray (left) and coloured oblique 3D computed tomography (CT) scan (right) showing a 61-year-old man with an artificial urinary sphincter (AUS, purple). A urinary sphincter is a muscle that acts as a valve and controls the amount of urine leaving the bladder. This patient has had a prostatectomy (prostate gland removal), which damaged the sphincter and caused incontinence. The large purple mass in the pelvis at right is a pressure regulating balloon that enables the urine to flow at an even rate when the artificial valve is open. The smaller masses beneath it are the artificial valve and a pump that is used by the patient to initiate urination.
