What are urogenital fistulae?
A fistula is an abnormal duct or passage between organs or vessels that normally do not connect. A urogenital fistula is an opening into the urinary tract. One type of female fistula is a vesicovaginal fistula, an abnormal tract between the bladder and the vagina. This fistula causes a continuous, involuntary discharge of urine into the vagina. Prolonged labor during childbirth is often the cause of a vesicovaginal fistula.
