Bilateral ureteral polyps in children: a case report

Fibroepithelial polyp of the ureter is a benign tumor of mesodermal origin that rarely occurs in children. The most common presenting symptoms are hematuria and flank pain by obstruction of the urinary tract. The etiology of this tumor is still not clear. It occurs more frequently in boys and often arises in the proximal ureter and the ureteropelvic junction. The preoperative diagnosis is difficult. We present here the case of a 11-year-old boy who had fibroepithelial polyps as the cause of the left flank ureteropelvic junction obstruction at pyeloplasty, and had the same condition on the right flank 5 years ago. We used polypectomy and pyeloureterostomy to treat the boy. No major intraoperative or preoperative complications developed.
