Secondary bladder exstrophy repair with a bilateral gracilis muscle flap in an adult female patient: Case report of an original procedure.

Classical bladder exstrophy (CBE), affecting 1 birth out of 30,000, is characterized by an evaginated bladder plate through a defect in the lower abdominal wall, multiple abdominal wall anomalies including a pubic bone arch dehiscence. Numerous approaches from childhood to adulthood are thus required, depending on the severity of the deformity, including the associated genital anomalies. We report the case of a 19-year-old woman with CBE with a history of three-failed primary closure. We performed a secondary neck closure with a concomitant suspension of the bladder neck and reconstruction of the lower abdominal wall using a bilateral gracilis muscle flap transposition. The early postoperative course was uneventful. The patient was discharged at day ten postoperatively. The upper part of the genital sutures (labia minora) secondary healed in three weeks. Assessment at 2, 6 and 16 months postoperatively, respectively noticed a complete healing with successful sexual intercourses, perceived gracilis contraction by the patient, and finally, recent attempts to get pregnant. Neither urinary infection nor urinary leaks occurred. Bilateral crossed gracilis muscles transfer linking both rectus abdominis muscle in front of the reconstructed bladder neck might benefit to bladder exstrophy patients.
