説明

The influence of pulsed dye laser on canine urinary tract was studied macroscopically and microscopically.<BR>Experiments were performed on canine bladder and ureter immersed in saline or in the air. The thermal elevation on the bladder mucosa was measured on thermography. Unlike the Nd-YAG laser there was very little change in the temperature at the tip of the fiber. There was very little change on the bladder and ureter wall after radiation of the extirpated bladder and ureter. Vessels in the living bladder were easily damaged by this laser, and the submucosal hematoma and bleeding was formed. But the muscle layers on the bladder and ureter wall were seldom damaged by this laser even at high power, if the duration was short.<BR>In result the pulsed dye laser made little damage on the urinary tract wall but destroyed the stones easily in the experiments. We attemt to use this new powerful and safe tool to the clinical cases with urinary stones.
