[Endoscopic resection of tumor of the renal pelvis]

We report on a patient who was submitted to percutaneous resection of a solitary, low grade urothelial transitional cell tumor of the renal pelvis. A review of the literature shoned endourologic treatment to be a valid in carefully selected cases. The measures to minimize the risk of tumor spread and the good results obtained are discussed. However, a longer follow up and larger series are necessary in order to draw definitive conclusions.
