Evaluations of laser lithotripsy using multiple pulses

Lithotripsy with a Holmium laser is painless using an optical fiber catheter in the urinary tract with a minimally invasive surgical procedure. A video clip of the lithotripsy of the urinary stone phantom was obtained using a high-speed camera, and the lithotripsy results were visually evaluated. This result shows that precise lithotripsy is possible by multiple laser pulses by using the developed Holmium medical laser system.
