Re: Safety of a Novel Thulium Fibre Laser for Lithotripsy: An In Vitro Study on the Thermal Effect and Its Impact Factor

摘要： Peng et al present for the first time data regarding the temperature rise following activation of a thulium fibre laser (TFL) for lithotripsy. In an in vitro setting, the thermal effect of TFL was evaluated at different laser power settings and irrigation rates with the safety temperature threshold set to 43°C. Without irrigation, laser power >10 W caused an increase in temperature above this safety threshold. When low-flow irrigation (15 ml/min) was used, only laser power of 30 W exceeded the safety threshold. Higher flow rates prevented a rise in temperature above the threshold for any of the laser settings tested.
