Laparoscopic management of extensive ureteral fibroepithelial polyps.

Fibroepthelial polyps are uniformly benign tumors of the collecting system which may cause obstruction of an affected renal unit. We present a unique case of a 34-year-old male with a solitary functioning kidney who presented with flank pain and renal insufficiency. Radiographic and ureteroscopic evaluation revealed ureteral obstruction due to extensive polyps.
