[The Martius flap in the treatment of vesicovaginal fistulas. Report of 20 cases].

The authors report a series of 20 cases of vesicovaginal fistula (VVF) treated according to the Martius procedure. The mean age of the patients was 30 years (range: 20 to 37 years). All fistulas were secondary to obstetric trauma. The mean diameter of the fistula orifice was 4 cm. Fourteen fistulas were cervico-trigonal and 6 were urethro-cervico-trigonal. A rectovaginal fistula was associated with VVF in 2 patients. Five of the 20 patients had never been previously operated, while 15 patients had already been operated without success. Fifteen patients were cured immediately, while a second Martius procedure was necessary in 3 cases. Failure was considered to be definitive in 2 cases.
