The fragmentation efficiency on Bego artificial stones during lithotripsy and the propulsive effect (via video tracking) was investigated for a variety of laser settings. A variation settings (pulse energy, pulse duration, repetition rate) altered total application time required stone fragmentation, break up time, propulsion. obtained results can be used to develop devices providing an optimal combination low propulsion high efficacy, which then evaluated in clinical setting. Additionally, fluorescence human kidney inspected endoscopically vivo. Fluorescence light detect stone-free areas or clearly distinguish calculi from surrounding tissue operation tools.
