Summary: We report a case of acute renal failure secondary to bilateral clot-induced ureteral obstruction, following prophylactic stent placement during laparoscopic radical hysterectomy (LRH). A 60-year-old patient with cervical adenocarcinoma stage IBI underwent LRH with prophylactic ureteral stent placement; the stent was removed postoperatively. Five days postoperatively, she developed acute renal failure secondary to blood clot-induced ureteral obstruction associated with urinary tract injury and anticoagulant therapy. She improved following cessation of anticoagulant therapy and ureteral stent re-insertion. Clinicians should be mindful that acute renal failure can occur secondary to blood clot-induced obstruction in patients who undergo prophylactic ureteral stenting.
