Bone-anchored sling created with the invance ™ system for the treatment of incontinence after radical prostatectomy: Initial experience in Japan

Abstract

This report describes creation of a bone-anchored sling with the invance ™ system (American Medical Systems, Minnetonka, MN, USA) for the treatment of 2 patients with incontinence after radical prostatectomy. The invance ™ system uses a silicon-coated polyester sling positioned under the bulbar urethra via a perineal incision. The sling is attached to both ischiopubic rami by 3 titanium screws. Operative times were 157 minutes (patient 1) and 240 minutes (patient 2). Blood loss was 70 mL (patient 1) and 10 mL (patient 2). The patients used 7 and 5 absorbent pads/day, respectively, before surgery and 1 and 0 pads/day after surgery (this datum does not appear in the main text, although the absence of incontinence is mentioned). The only major adverse event encountered was mesh infection necessitating mesh removal in patient 2. This operation appears comparatively simple and useful.
