文摘DRIMARY benign ureteral tumors are rare and they arise from the mesodermal tissue of the ureteral wall. Less than 200 cases have been docu- mented in published reports.1 Bilateral ureteralfibroepithelial polyps are extremely rare and commonly occur in the proximal ureter, causing complete ureteral obstruction. Pyeloplasty is an effective treatment for im- proving renal function. Here we report a case with se- quential bilateral ureteral fibroepithelial polyps causing obstructive hydronephrosis.
