Comparison of Ho:YAG and Er:YAG Lasers for Lithotripsy

Popis výsledku v původním jazyce

The contemporary medicine heads towards the minimally-invasive diagnosis and treatment methods. Laser-assisted lithotripsy is a minimally-invasive method for destroying or disruption of human urinary stones. For the purpose of minimally-invasive laser light delivery the optical fibres or sealed and flexible hollow waveguides are used. In this study we have compared the ablation effect of Ho:YAG laser (with the generated wavelength 2100 nm) and Er:YAG laser (with the generated wavelength 2940 nm) on theartificial samples (special compressed plaster) and human urinary stones in vitro. The ablation or perforation rates were measured and compared for both laser systems, various pulse energy levels and various interaction samples thickness. The interactionenvironment was water with temperature 25°C. Finally both lasers were tested for human urinary stones lithotripsy in vitro.
