title: Bilateral renal fornix rupture following intraarterial contrast medium application for infrarenal aortic stent placement.
abstract: A 74-year-old male claudicant who had a significant abdominal aortic stenosis was hydrated before aortic stent placement because of an elevated creatinine level. During the intervention the patient experienced acute abdominal pain with vomiting. No vascular cause was detected. Due to persistent pain, plain radiography and an abdominal CT scan were performed a few hours after the procedure. Images revealed a bilateral renal fornix rupture with a large retroperitoneal fluid collection. The patient was treated conservatively with ureteral double-J placement and percutaneous nephrostomy. The further course was uneventful and the patient was discharged 2 weeks later free of symptoms. Renal fornix rupture is a very rare complication after contrast medium application that can be treated without surgery.
