Abstract

Purpose: We evaluated the ability of KTP laser to evaporate prostatic tissue in vivo and compared the results with historical Nd:YAG treated controls. Methods: Five dogs underwent anterograde transurethral evaporation of the prostate (TUEP) with KTP laser at 38 watts and were sacrificed 48 hours after surgery. Results: All procedures were hemostatic and without complications. Laser evaporation produced cavities within the prostate ranging from 2.5 to 3.2 cm in diameter (average equals 2.9 cm) that were free of necrotic tissue. Conclusions: Preliminary findings in this initial canine study of laser evaporation of the prostate, show that KTP laser produces large spherical cavities within the prostate in a hemostatic fashion. These cavities are free of necrotic tissue. In addition, these cavities are comparable in size to those that have been observed 4 to 8 weeks following Nd:YAG VLAP and are significantly larger than the acute cavities produced by Nd:YAG TUEP.
