Artificial Urinary Sphincter in Nashville, TN
Urinary Incontinence Treatment
The artificial urinary sphincter (AUS) is a medical device used to treat severe urinary incontinence. It is often used in men who suffer from stress or urinary incontinence following a radical prostatectomy, which is the surgical removal of the prostate gland to treat cancer. The device is completely concealed inside the body and mimics a healthy sphincter by opening and closing the urethra.
The artificial urinary sphincter has an inflatable cuff that fits around the urethra near the point where it joins the bladder. When inflated, the cuff keeps the urethra shut to keep urine from leaking.
A pump is placed in the scrotum to control inflation and deflation of the cuff. The pressure of the cuff is regulated by a balloon, which is surgically placed within the pelvic area under the abdominal muscles. To urinate, the cuff is deflated by squeezing the scrotal pump, allowing urine to drain out. The cuff automatically re-inflates on its own after several minutes to close the urethra and restore bladder control.
The artificial urinary sphincter procedure can be performed as an outpatient or inpatient surgery under general anesthesia. Since it is placed entirely within the body, it is undetectable to others. After a healing period of 6 weeks, patients return to Dr. Knoll’s office to have the device activated.
Dr. L. Dean Knoll has restored continence with the artificial urinary sphincter in thousands of men worldwide who suffer from bothersome leakage. These procedures are among the most rewarding for Dr. Knoll and are a primary focus of his practice.
