Comparison of p-Tm:YAG, TFL and Ho:YAG's in vitro ablation rates on synthetic and human stones.

ABSTRACT:

Objective

To compare in vitro the ablation rates of p-Tm:YAG, TFL and Ho:YAG against synthetic and human stones.

Material and methods

p-Tm:YAG, TFL and Low-Power (LP) Ho:YAG were compared using 270 μm core-diameter laser fibres (CDF); experiments with 200 μm(p-Tm:YAG) and 150 μm-CDF (TFL) were also included. A continuous laser emission was applied through a spiral trajectory for 20 seconds with the laser fibre tip in contact with synthetic hard (HSP) and soft stone phantoms (SSP) submerged in saline. "Dusting" settings for p-Tm:YAG(0,6 J-20 Hz-Flex Long Pulse), TFL(0,5 J-30 Hz-Short Pulse) and Ho:YAG(0,5 J-30 Hz-Long Pulse) and "Fragmentation" settings for p-Tm:YAG(1 J-15 Hz-Captive), TFL(1 J-15 Hz-Short Pulse) and Ho:YAG(1 J-15 Hz-Long Pulse) were analysed. Then, experiment
