title: [Ureteral polyp in childhood: a case report].
abstract: An 8-year-old boy was admitted because of left flank pain. The excretory urogram showed left hydronephrosis and a filling defect at the pelviureteric junction. Surgical exploration revealed a polypoid lesion on the mucous membrane of the pelviureteric junction and ureteric stenosis due to a periureteric fibrous band. Dis-membered pyeloplasty was performed. The pathological diagnosis was benign fibrous polyp of the ureter. Convalescence was uneventful and an intravenous pyelogram showed no evidence of recurrence one year after operation. We found 13 cases of ureteral polyps in children in the Japanese literature. The differences between ureteral polyps in childhood and those in adults are discussed.
