How can a urinary fistula be treated? 

Treatment ranges from conservative maneuvers such as bladder catheterization to the need for surgery. The type of surgery depends on the origin and size of the fistula and may require a vaginal, abdominal or laparoscopic approach. In cases of fistulas from the urinary tract to the digestive tract, a colostomy may be required, i.e. a bag to collect the feces.
