ABSTRACT
This experimental study demonstrates the absence of irreversible tissue damage after lithotripsy with a pulsed dye laser. The absence of thermal damage with this laser is due to the beam divergence capacity at the end of the fiber and to the short pulse, which generates very low thermal effect. These results as a whole confirm the safety of the pulsed dye laser and indicate that it can be used for clinical treatments in humans.

The tissue effects of pulsed dye laser (Pulsolith) were studied in 10 dog ureters. The results show the absence of ureteric perforation or damage to adjacent organs by the laser irradiation. The only lesions observed were focal hyperplasia of the urothelium and chorion with extremely limited abrasions of the urothelium. The absence of tissue damage of the pulsed dye laser allows it to be used in human clinical practice.
