[Closure of a neobladder-vaginal fistula in a patient with Studer's type neobladder using a transvaginal approach with interposition of a Martius' flap].

Objective: We report a case of neobladder-vaginal fistula in a patient, and its closure using a Martius flap interposition.

Methods: A 51-year-old patient required cystectomy and Studer's neobladder for invasive bladder adenocarcinoma. After urethral catheter removal she presented constant leakage and was diagnosed by cystoscopy of neobladder-vaginal fistula.

Results: This complication was successfully treated using a vaginal approach with closure in two layers and interposition of a Martius flap.

Conclusions: Neobladder is a rare indication in women, as it is the eventuality of presenting this type of fistula. The adequate approach to treat it is still controversial. In our experience and after reviewing literature we think vaginal closure using a Martius flap interposition is a good technique to treat a neobladder-vaginal fistula.
