A non-traumatic rupture of renal pelvis during pregnancy is an extremely rare complication. The authors report a case of bilateral rupture of the renal pelvis in a multiparous female who underwent emergency cesarean section during vaginal birth after previous cesarean section, owing to abrupt and massive vaginal bleeding and prolonged fetal late deceleration. During surgery, a disproportionately enlarged uterus was noted and postoperatively severe oliguria was complicated with a sustainable amount of packed RBCs transfusion. CT revealed extravasation of contrast media around bilateral perinephric space. Treatment course and review of the cause of renal pelvis rupture is discussed along with literature study.
