Endometriosis arises from implant of endometriotic cells outside the uterus: a report of active vesicouterine centrifugal fistula.

Vesicouterine fistula is rare, accounting for nearly 4% of all urogenital fistulas. Lower segment cesarean delivery is the main predisposing event but in the last few years other possible predisposing factors have been pointed out. Clinically, it can show itself in different forms and the diagnosis is often delayed although it is not difficult. We report our experience about a case of postcesarean vesicouterine fistula arising on a focus of vesical endometriosis and we discuss an eventual hypothetical pathogenetic correlation between bladder endometriosis and uterovesical fistula.
