Late Distal Ureteral Stricture in Internal Hemipelvectomy Without Bone Reconstruction: A Case Report

We report the case of a patient with Ewing sarcoma involving the right pelvis in a 14-year-old girl who had multicycles of neo-adjuvant chemotherapy and preoperative radiation therapy. She underwent an internal hemipelvectomy type I resection, according to Enneking and Dunham’s classification without bony reconstruction. There was no intra- and perioperative complication. The patient has good function and needs no gait aids. She can walk with equinus foot compensated for leg shortening 5 centimeters and without a shoe-lift. There is no sign of disease relapse. However, she developed late ureteral stricture at 8-year postoperatively and was successfully treated with a ureteral stent.
