摘　　要：To the Editor: Ureteral calculus is a common urological disease. In recent years, one of the main treatment methods is ureteroscopy with holmium laser lithotripsy. However, with the extensive application of holmium laser lithotripsy, the increasing incidence of postoperative ureteral stricture or even occlusion has attracted the attention of clinicians to its etiology. The issue of the intraoperative holmium laser thermal effect has also gradually gained attention. The holmium laser is a long-wavelength pulsed laser, which crushes calculi by an optomechanical/photoacoustic mechanism as well as a photothermal mechanism, and it is mainly based on the photothermal mechanism.[1] Currently, multiple in vitro studies worldwide have confirmed that the holmium laser did increase the water temperature in the working area. However, these studies only simulated the lithotripsy process of the holmium laser in vitro, which did not completely reflect the thermal effect of the holmium laser during an actual operation. Accordingly, this study monitored the temperature changes of the lavage fluid in the operative field during the actual holmium laser lithotripsy process under an ureteroscope, with the aim of providing more information for the etiology study of ureteral stricture after ureteroscopy with holmium laser lithotripsy.
