Holmium:YAG lithotripsy requires transmission of optical energy using laser fibers. Optical fibers may be subjected to severe angular deflection and bending during flexible nephroscopy or flexible ureteronephroscopy. Irradiation of a deflected fiber in a tight bending radius may produce fiber failure and consequent irradiation of the ureteroscope, with risk of instrument damage and patient injury. We review the physics and engineering aspects of optical fibers to explain why fibers fail.
钬激光碎石术需要使用激光纤维来传输光能。在软性肾镜检查或软性输尿管肾镜检查过程中，光纤可能会受到严重的角度偏转和弯曲。在弯曲半径很小的情况下照射偏转的光纤可能会导致光纤损坏，进而照射输尿管镜，存在仪器损坏和患者受伤的风险。我们回顾光纤的物理和工程方面知识，以解释光纤为何会损坏。
