title: [Percutaneous resection of renal pelvic fibroepithelial polyp with medullary sponge kidney: a case report].
abstract: Benign polyp of the renal pelvis is extremely rare. We report a case of fibroepithelial polyp in the renal pelvis complicated with medullary sponge kidney successfully treated by percutaneous resection. The patient had recurrent bilateral renal stones because of medullary sponge kidney. Percutaneous resection of renal pelvic polyps was carried out through a 26 Fr Amplatz sheath using a 24 Fr resectoscope. Pathological diagnosis was a fibroepithelial polyp. The etiology of this polyp was suggested to be chronic irritation of renal stone.
