Official Title: Diagnostic Relevance of Laser Confocal Microscopy During Reno-ureteroscopy in the Context of the Screening and Follow-up of Upper Urinary Tract Tumors
Brief Summary: Upper Urinary Tract Tumors have an incidence of 1 to 2 cases for 100 000 persons per year. The standard treatment for these tumors is the ablation of the kidney, ureter and a part of the bladder surrounding the ureteral orifice. The development of new diagnosis and treatment techniques through natural routes opens the possibility to use conservative treatments. The investigators hypothesis is that during a reno-ureteroscopy, laser confocal microscopy will allow the discrimination between normal and pathologic urothelium by microscopic analysis. This will prevent the systematic use of biopsies which are often difficult and iatrogenic.
