[A case of ureteral polyp in a young man with renal autotransplantation].

We report a case of fibroepithelial polyps of the ureter in a 18-year-old boy with the chief complaint of left flank pain. An excretory urogram and retrograde pyelogram revealed left hydronephrosis and a filling defect at the pelvic-ureteral junction. This ureteral disorder was corrected by the renal autotransplantation for conserving the renal function. The pathological diagnosis was fibroepithelial polyps of the ureter. Convalescence was uneventful and after 3 months of follow up, excretory urogram and 99mTc-DTPA renogram showed good renal function and improvement of hydronephrosis. Along with our case, we briefly reviewed 32 cases of ureteral polyp in men under 20 years old.
