We report a 28-year-old man who presented with hematuria and intermittent flank pain. Conventional CT urography showed mild left hydronephrosis and an undetermined lesion in the left ureter. By virtual CT ureteroscopy, a fibroepithelial polyp (FEP) was preoperatively diagnosed. The patient had segmental resection of the ureter and pathological proof of FEP was obtained.
