A cervix penetrating the posterior bladder wall: case report.

Clinical manifestations of vesicouterine fistulas, a rare complication of cesarean section, include amenorrhea and cyclic hematuria (menouria) without urinary incontinence, a triad collectively known as "Youssef's syndrome." Fistulas affecting the uterus usually reside above the isthmus or at the cervix and have a distinct morphology composed of granulation tissue, chronic inflammatory cells, and fibrous tissue. We present a case of Youssef's syndrome where the patient's entire cervix penetrated into the posterior bladder wall rather than the two organs connecting via a discrete fistulous tract.
