Endoscopic treatment of urothelial tumours of the renal pelvis and ureter.

Endoscopic treatment of urothelial tumors of renal pelvis and ureter is gaining acceptance as a conservative treatment modality. Technological advances have increased its applicability. Ureteroscopic and percutaneous tumor ablation have become reasonable treatment options for patients with imperative indications, such as bilateral disease, renal insufficiency or solitary kidney. However, endoscopic tumor ablation is being utilized more frequently for patients with UTTCC even in the setting low grade disease and a normal contralateral kidney, provided long-term close surveillance to detect and treat recurrences is ensured. This paper reviews the current role of endoscopic management of UTTCC.
