Which Patients with Upper Tract Urothelial Carcinoma Can be Safely Treated with Flexible Ureteroscopy with Holmium:YAG Laser Photoablation? Long-Term Results from a High Volume Institution

Abstract

High tumor grade independently decreased progression-free survival in patients with upper tract urothelial carcinoma treated with Ho:YAG laser photoablation. Tumor size greater than 1 cm and multifocality did not increase the risk of disease progression in patients treated conservatively with Ho:YAG laser photoablation.
