Implication

In vitro study comparing stone ablation volume from thulium fiber and Ho: YAG lasers, highlighting implications for clinical applications.

Key Points

This research aims to compare the stone ablation volumes achieved by thulium fiber laser and high-power Holmium: YAG lasers using various pulse modulation technologies.
Used BegoStone phantoms with a 15:6 powder-to-water ratio.
Applied lasers at a constant speed (0.7 mm/s) with defined settings (1.5 J × 5 Hz, 1 J × 20 Hz, 0.3 J × 50 Hz).
Calculated ablation volume from measurements with an optical microscope and performed ANOVA analysis.
TFL-200 μm achieved the highest ablation volume at 1.5 J x 5 Hz (15.9 mm³), significantly outperforming other technologies (p < 0.05).
At 1 J x 20 Hz, TFL-200 μm (21.2 mm³) exceeded all other technologies (p < 0.001).
TFL-150 μm showed similar ablation volume to Ho: YAG except in cases of significant depth differences.
