Effects of pulsed dye laser lithotripsy on tissues. Experimental study in the canine ureter.
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.
