The Mainz II pouch: experience in 5 patients with bladder exstrophy.

Abstract

We report our experience with 5 patients with bladder exstrophy who underwent creation of a Mainz II pouch. We retrospectively reviewed the results of the Mainz II pouch as a primary urinary diversion in 2 and a secondary urinary diversion in 3 patients. Each patient underwent multiple surgeries, including osteotomy in 1. All patients were followed postoperatively on a yearly basis. All patients are continent and the upper urinary tract is stable. The Mainz II pouch is appropriate for children born with a small fibrotic bladder, and as a salvage procedure for those who have endured multiple reconstructive procedures and remain incontinent. Furthermore, this procedure deserves serious consideration in children residing in developing countries.
