Abstract
Fibroepithelial polyps of the ureter are benign tumors arising from mesodermal tissue in the ureter wall. They are extremely rare lesions that can cause ureteropelvic junction obstruction in children. In this report, we describe an 11‐year‐old boy with fibroepithelial polyps of the ureter that caused left ureteropelvic junction obstruction. He presented with a 6‐month history of left abdominal and flank pain. He also had short stature. Intravenous pyelography showed hydronephrosis without filling defects at the left ureteropelvic junction. Exploration revealed several finger‐like polyps obstructing the lumen. This area was resected segmentally and a dismembered pyeloplasty was performed. No complications occurred during the postoperative period. The boy caught up in growth after the operation. Fibroepithelial polyps were confirmed by histology.
