Placenta percreta is potentially a life-threatening condition. Pelvic organ invasion of the placenta carries high mortality and morbidity to the mother and fetus. We present a 33 year old gravida 3, para 2-0-0 female with placenta previa, percreta with bladder invasion. Placental invasion caused a giant vesicouterine fistula. The pregnant woman was managed conservatively until 33 weeks gestation, at which time she underwent a classical cesarean section. Postoperatively the patient was treated with methotrexate. Immediately postpartum the placenta was left in situ and successfully removed transvaginally after 11 weeks postpartum.
