Prospective randomized comparison of repairing vesicovaginal fistula with or without the interposition flap: Result from a tertiary care Institute in Northern India.

The success rates are similar in simple VVF repair (fistula size less than 4 cm) irrespective of the use of interposition flaps. However, overall morbidities following repair with the interposition flap are higher when compared with repair without interposition flap, either by the transvaginal or by the transabdominal route.
