UNASSIGNED: A 63-year-old female patient presented for the management of a staghorn pelvis-lower calyceal stone. The patient had a preoperative computed tomography scan of the abdomen and pelvis that showed an incidental finding of left retrorenal colon. Under computed tomography scan guidance, a nephrostomy tube was successfully placed by an interventional radiologist, and then she underwent percutaneous nephrolithotomy.
UNASSIGNED: This case report aims to stress on the importance of doing a computed tomography scan whenever a prior abdominal surgery is performed. We strongly believe that gastrointestinal injuries could be avoided by using computed tomography guided access in high risk patients.
