Flaps and Grafts in Robotic Reconstructive Surgery.

Abstract

Purpose of review: The robotic approach is increasingly popular in reconstructive urology. Reconstructive surgeons have commonly used flaps and grafts for obliterating dead space including tissue interposition or as an alternative to mesh in addressing lower urinary tract dysfunction. Advantages of the robotic approach are less incisional pain, excellent visualization in the deep pelvis, and improved surgeon ergonomics. In this literature review, we describe flaps and grafts used in lower urinary tract robotic reconstructive urology, serving as an almanac for these techniques.

Recent findings: Omental, peritoneal, vertical rectus abdominis musculocutaneous (VRAM), sigmoid epiploica, gracilis flaps, and Alloderm^™ have been reported for tissue interposition during fistula repair. Fascia lata has been described as a mesh alternative for robotic sacrocolpopexy. Besides providing interposition, flaps support native tissue healing and blood supply. Grafts are easy to use with low patient morbidity, but rely on the blood supply at the recipient site. Robotic reconstruction is an emerging field, and more studies are needed to define the best uses for each flap and graft as well as strategies to maximize outcomes and minimize morbidity.
