Abnormal passageways or fistulas can exist between the vagina and bladder, ureters, uterus, and rectum with the resulting passage of urine from the vagina, or intestinal gas and feces into the vagina, in the case of a vaginal–rectal fistula. These vaginal fistulas are named according to the origin of the defect: * vesicovaginal * urethrovaginal * ureterovaginal * vesicocervical * vesicouterine * vesicouretovaginal * uterocervical * vesicocervical * uretercervical * ureteruterine The vagina is susceptible to fistula formation because the gastrointestinal tract and urinary system are relatively close to the vagina. A small number of vaginal fistulas are congenital. The presence of a vaginal fistula has a profound effect on the quality of life since there is little control over the passage of urine and feces through the vagina.<unk> s are often classified according to their cause: obstetric fistula, congenital fistula and iatrogenic fistula.<unk> s can be classified by size and more specific anatomical location such as 'upper vagina' or 'posterior vaginal wall'.
