In vitro study concerning the efficiency of the frequency‐doubled double‐pulse Neodymium:YAG laser (FREDDY) for lithotripsy of calculi in the urinary tract

In a preclinical study we have tested both in vitro and in vivo, a new type of pulsed solid‐state laser system that has not been applied in urology so far and has been developed for optimized intracorporal lithotripsy of biliary, salivary, and urinary calculi.
