title: The use of human dura mater as an interposition graft in the treatment of vesicovaginal fistula.
abstract: OBJECTIVE
  In this prospective study we aimed to describe our new technique; dehydrated human dura mater as an interposition graft in patients undergoing benign vesicovaginal fistula repair (VVF).
  
  
  METHODS
  Eleven patients with benign VVFs aged 38-73 years were operated with dura mater interposition technique at our institution between July 1996 and February 2002. In all patients fistula were secondary to abdominal hysterectomies with benign diseases and two had undergone previous transvaginal surgery. Patients were operated 8-15 (mean 12) weeks after previous surgery. A suprapubic cystotomy was performed and the fistula was not excised. The bladder wall is widely dissected from underlying vagina. Dura-mater was placed over the vaginal suture line to close the fistulous tract, cytostomy was inserted and the bladder was closed. An 18 F Foley catheter was left in the bladder for 5 days. A successful repair is defined as no leakage by cystogram at 14 days postoperatively and completely dry by patient report.
  
  
  RESULTS
  An overall success rate of 100% was achieved in all patients. All patients remain dry at the follow-up which ranges from 7 to 60 (mean 26) mounts. Patients were discharged at 14 to 26 (mean 16) days postoperatively. No major complications or side effects were observed during the follow-up period.
  
  
  CONCLUSIONS
  The use of human dura mater as an interposition graft in the treatment of vesicovaginal fistula is an alternative for VVF repairs because of its excellent tissue compability, stability, good elasticity and absorbability.
