We reported a case of ureteral polyp in a 12-year-old boy whose chief complaint was asymptomatic gross hematuria. An excretory urogram revealed severe right hydronephrosis with a filling defect of the upper ureter. Our diagnosis was right hydronephrosis due to the ureteral polyp. A partial ureterectomy with an end-to-end anastomosis was performed. A polyp was found in the excised ureter and the histological diagnosis was a fibroepithelial polyp. Six months after the operation, the right hydronephrosis showed remission.
