Abstract

We report preliminary potato dosimetry and canine studies evaluating a new 1,000-(mu) optical fiber whose distal tip has been bent to 45 degree(s), allowing for endoscopic delivery of neodymium:YAG laser energy at an angle of 60 degree(s). Our results suggest that this fiber is comparable with other more complex angled delivery systems; has several advantages: it can deliver greater power over longer time intervals, producing larger volumes of coagulative necrosis, and it may be operated in a contact mode within a fluid medium without fiber `burnout.' This fiber should prove useful for transurethral laser ablation of the prostate.
