title: Ten-year experience with transvaginal vesicovaginal fistula repair using tissue interposition.
abstract: OBJECTIVE
  The success rate of vesicovaginal fistula repair is improved by tissue interposition. The Martius flap produces reliable results but it has increased morbidity. A peritoneal flap is easily created with minimal morbidity and it can be used for proximal fistulas. We describe our 10-year experience with tissue interposition for transvaginal repair of vesicovaginal fistulas.
  
  
  METHODS
  From January 1991 to July 2001, 207 cases of vesicovaginal fistulas were repaired transvaginally. Tissue interposition was used for complex (greater than 2 cm. and/or radiation induced) fistulas and/or failed previous repairs. A peritoneal flap was used for proximal fistulas and a Martius flap was used for distal fistulas. A full-thickness labial flap was reserved for cases of insufficient vaginal epithelium.
  
  
  RESULTS
  A total of 207 patients underwent transvaginal repair of a vesicovaginal fistula. Etiology of the fistula was hysterectomy in 91% of cases (abdominal in 83% and vaginal in 8%), radiation in 4% and 5% other (obstetric trauma, anterior colporrhaphy or an indwelling catheter) in 5%. In 159 patients (77%) at least 1 previous repair had failed. Repair in 120 patients (58%) was done with tissue interposition, including a peritoneal, Martius and full-thickness labial flap in 83, 34 and 3, respectively. The cure rate after initial repair with a peritoneal, Martius and labial flap was 96%, 97% and 33%, respectively. There were no intraoperative complications.
  
  
  CONCLUSIONS
  A peritoneal flap for transvaginal repair of vesicovaginal fistulas has minimal morbidity, results in a success rate comparable to that of the Martius flap and is especially useful for proximal fistulas when previous repair has failed.
