The conventional management of urogenital fistulas is surgical but a recent review of world data showed a high efficacy of hormonal manipulation by the induction of amenorrhea in the treatment of vesicouterine fistulas (VUFs). In fact, VUFs were first demonstrated to be hormonally regulated due to the fistulous canal being lined by endometrium. In this report, we suggest and discuss that, in women of reproductive age, the phenomenon of hormonal regulation is likely to be present in other fistulas communicating with the uterus, like ureterouterine and enterouterine fistulas.
