Objectives: The objectives are to present the long-term results of vaginal reconstructive operations using the labial fat pad flap (Martius flap) interposition.
Patients and methods: Eight women, 27-65 years old (mean 40), suffering from urinary fistulae (five urethrovaginal and three vesicovaginal) who failed primary repair underwent salvage vaginal reconstruction for damaged urethra or bladder. Urethral or bladder and vaginal defect was closed and a Martius fat flap was interposed between urethra or bladder and vaginal wall flap to secure a watertight separation of the structures. A Martius flap was also used successfully for salvage vaginal reconstruction in three more women, two with extensive injury of their urethra and bladder neck and one with vaginal leakage, after a rectosigmoid neobladder diversion following cystectomy.
Results: The repair was successful in all eight patients with urinary fistulae and in the one with rectovaginal leakage. The patient with the traumatically injured urethra and bladder neck developed an anastomotic stricture treated with urethral dilatations and internal urethrotomy. The older one developed a vesicovaginal fistula due to bladder neck closure, and this was repaired with a second transvaginal closure.
Conclusion: Martius labial fat flap is an easy to prepare, well-vascularized tissue that can be most helpful in achieving a long-lasting favorable outcome in vaginal reconstructive surgery.
