Thulium fiber laser lithotripsy: An in vitro analysis of stone fragmentation using a modulated 110‐watt Thulium fiber laser at 1.94 µm

摘要: Abstract Background and Objectives The high‐power Thulium fiber laser has previously been shown to rapidly vaporize and coagulate soft urinary tissues (eg, prostate). This is the first preliminary study of a high‐power Thulium fiber laser for fragmentation of urinary stones. Study Design/Materials and Methods A continuous‐wave, high‐power Thulium fiber laser operating at a wavelength of 1.94 µm, was modulated to operate in pulsed mode with an output pulse energy of 1 J through a 300‐µm‐core silica fiber at a 20 milliseconds pulse …
