During the procedure, the surgeon ligates multiple vessels in order to remove the entire uterus. In the immediate postoperative period, the patient develops left-sided flank pain and oliguria. Serum creatinine is found to be 1.4 mg/dl whereas it was 1.0 mg/dl prior to the operation. Renal ultrasound is normal. Urinalysis is notable for hematuria. Ligation of which of the following vessels most likely contributed to this patient’s condition?   (A) Artery of Sampson   (B) Ovarian artery   (C) Superior vesical artery   (D) Uterine artery
