[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.
