铥光纤激光是具有良好碎石潜力的新型激光，近年来在泌尿外科领域获得关注。本文从铥光纤激光的碎石机制、碎石效率、安全性及临床应用等方面进行探讨。铥光纤激光碎石机制与钬激光存在相似之处，但较钬激光碎石速度更快、碎石颗粒更细以及结石位移更小，其临床应用有望带来激光碎石领域的变革。“,”Thulium fiber laser is a novel laser of good potential in lithotripsy, which gained the attention of urology society in recent years. This article aimed to discuss Thulium fiber laser referring to lithotripsy mechanism, ablation efficiency, laser safety, clinical application and so on. Thulium fiber laser shares a similarity of lithotripsy mechanism with Holmium laser, whereas Thulium fiber laser has a higher ablation rate, thinner fragments, and smaller retropulsion compared to Holmium laser. Thulium laser may bring revolution in the field of laser lithotripsy.
