“…Up to 95% of stones can be completely fragmented, especially distal ureteric stones, rendering laser lithotripsy a challenge to ESWL as the primary mode of treatment. In contrast, in one study the fragmentation rate using the Alexandrite laser was only 50%, because of equipment malfunction and technical problems, and the authors did not recommend it as an effective lithotripter [ 28].…”

Since the mid-1980’s, many reports have demonstrated the clinical feasibility of fragmenting urinary and biliary calculi with high power lasers [1,2]. Several lasers such as pulsed dye, alexandrite and holmium:YAG have been successfully used as intracorporeal lithotriptors[3–5]. Calculus fragmentation is produced by the combination of direct thermal energy absorption and laser induced shock waves[5–7]. During this powerful laser-tissue interaction, the calculus is subject to a strong retropulsive momentum caused by particle ejection or laser induced shock waves[8]. If the stone cannot resist this kinetic momentum, it will recoil away from the laser delivery fiber. Then physicians must reorient the fiber to the stone for additional laser irradiation. This cumbersome process makes the procedure inconvenient and difficult and eventually prolongs the operation time. This study is designed to quantify the retropulsive momentum during pulsed laser lithotripsy.
