New surgical technique for sphincter urinary control system using upper transverse scrotal incision.

Purpose: Traditional implantation of the AMS Sphincter 800 Urinary Control System (American Medical Systems, Minnetonka, Minnesota) requires 2 incisions. The cuff is placed via a perineal incision, and the pressure regulating balloon and pump are placed through a separate suprapubic incision. We describe a novel implantation of all the artificial urinary sphincter components using a single upper scrotal incision. The scrotal incision allows excellent access to the proximal bulbar urethra and retropubic and subdartos spaces, and leaves the bulbocavernosus muscle intact.

Materials And Methods: A total of 37 patients have undergone artificial urinary sphincter implantation using the new operative technique for revisions or reimplantations of a sphincter previously removed for infection/erosion (12) or as an initial procedure (25). In 9 of the 25 patients and 2 of the 12 dual implantation of a 3-piece penile prosthesis through the same incision was performed.

Results: All patients are using the devices. Of the patients 66% are completely dry with no pad use and the remainder use 1 pad for accident prevention. Operative time was reduced due to easier exposure of the urethra and a second incision for placement of the pressure regulating balloon was not necessary. Followup at 1 year shows no difference in complication rate with the single incision technique compared to the traditional method.

Conclusions: Artificial urinary sphincter implantation through a single scrotal incision is easier and faster than the traditional 2-incision technique. Success in achieving continence is similar to traditional methods. Long-term followup is necessary to ensure that complications remain low.
