Clinical Report: Evaluation of Thulium Fiber and High-Power Holmium: YAG Lasers
Overview
This study compares the ablation volume achieved by thulium fiber laser (TFL) and various pulse-modulated holmium: YAG lasers using an artificial stone model.
Background
The evolution of laser technology in endourology is critical as it impacts the effectiveness of lithotripsy for urinary stones. Holmium: YAG (Ho: YAG) lasers have been the standard for stone fragmentation, but thulium fiber lasers (TFL) are emerging as potential alternatives with improved performance characteristics.
Data Highlights
No numerical data provided in the source material.
Key Findings
The study evaluated TFL and next-generation pulse-modulated Ho: YAG technologies, including MOSES™, VB™, VT™, and Magneto.
Ablation volume was assessed using BegoStone phantoms to simulate urinary stones.
Different energy-frequency combinations were tested for both TFL and Ho: YAG lasers.
Pulse modulation techniques were compared, highlighting the differences in retropulsion and dusting efficiency.
The influence of laser fiber diameter on lithotripsy efficiency was also examined.
Clinical Implications
The findings provide information on TFL and its performance in lithotripsy.
Conclusion
The comparative analysis of TFL and Ho: YAG lasers presents findings on their performance in lithotripsy.
