Abstract
INTRODUCTION: Female urethral complete transection caused by pelvic trauma is extremely rare, and no standard management has been established when urethral reconstruction is not feasible. CASE PRESENTATION: A woman in her twenties sustained an open pelvic fracture with perineal injury due to a traffic accident. Complete urethral transection was identified, and a suprapubic cystostomy was placed. After staged vaginal reconstruction and bladder function evaluation, a Mitrofanoff appendicovesicostomy was performed. Because the appendix was not enough to reach the umbilicus, a Boari flap was created to compensate for the length. Urodynamic evaluation showed improvement from a preoperative high-pressure bladder to increased compliance postoperatively, though pharmacological management was still required. Postoperatively, the patient achieved stable clean intermittent catheterization without complications. CONCLUSION: The Mitrofanoff procedure can be an effective option in female urethral injuries where reconstruction is impossible. The addition of a Boari flap may expand its applicability by overcoming conduit length limitations.
