Combined Interposition of a Pedicled Greater Omentum Flap and a Rectus Abdominis Muscle Flap for Reconstruction of Adult Bladder Exstrophy: A Multidisciplinary Approach, A Case Report

Bladder exstrophy is a rare congenital malformation that is usually treated during the neonatal period. Management in adulthood becomes particularly challenging in the setting of multiple prior reconstructions and combined vesical and parietal complications. We report the case of a 26-year-old woman followed for bladder exstrophy, complicated by a vesico-parietal tissue defect with urinary leakage in the context of stone formation in an augmented bladder. She underwent reconstruction using the combined interposition of a pedicled greater omentum flap and a rectus abdominis muscle flap. The postoperative course was favorable, with resolution of the leak, complete healing at three months, and satisfactory functional outcome. This case highlights the value of this reconstructive strategy in complex forms of adult bladder exstrophy.
