• 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. After ureteral stenting and normalization of renal function, successful polyp excisions were performed laparoscopically through a ureterotomy. The pathology revealed benign fibroepithelial polyps. The patient remained asymptomatic until 3 years later when ureteroscopy performed for a calculus revealed a widely patent lumen free of polyps. To our knowledge, this is the first published report of a long term follow up after laparoscopic resection of extensive ureteral fibroepithelial polyps.
