Abstract:
In order to assess the thermal effect of different holmium laser fiber during lithotripsy with WOLF F4.5/6.5 pediatric ureteroscope, we established an impacted ureter calculi model. Under 100mmHg irrigation pressure, regional temperature of different holmium laser fiber with varied working time and power were recorded. We found that the regional temperature was related with laser fiber diameters, power and working time settings. With 550 μm laser fiber, laser firing time longer than 3 s or 365 μm laser fiber firing more than 6 s, regional temperature exceeded 42℃, which would bring thermal injury towards ureter and subsequently cause ureter stricture.
