DALLASA 58-year-old prostate cancer patient who developed stress urinary incontinence after successful prostatectomy was the first man at the University of Texas Southwestern Medical Center to receive a new type of sling to prevent leakage, the AdVance Male Sling System, from American Medical Systems, Minnetonka, Minnesota (see Figure).
The device has been available since August 2006, but Allen Morey, MD, was the first to use the device at UT Southwestern. Dr. Morey, professor of urology, joined the UT Southwestern faculty in June as a subspecialist in reconstructive urology.
Although slings have been used for years in women to improve urinary control, they are a relatively new treatment for men, Dr. Morey said. Prior slings were anchored to the pelvis with small bone screws to secure fixation, but that was painful for many patients.
The new device involves passage of a thin strip of mesh between pinpoint incisions on the inner thighs, which is then passed deep beneath the bottom of the urethra to increase support in precisely the area where the tissues are weakened. This additional flow resistance prevents the leakage of urine when abdominal pressure increases.
The procedure is best suited for mild-to-moderate stress urinary incontinence, usually defined as patients who wear one to four pads per day to absorb any leakage.
More than 2 million men worldwide suffer from stress urinary incontinence, and a majority of these men are prostate cancer survivors, having undergone surgery for the treatment of their cancer with the often unavoidable outcome of a damaged urinary sphincter.
