✦ Synopsis

The pulsed dye laser (wavelength 504 nm, pulse duration 1 ps) is widely used for fragmenting urinary and biliary calculi. In this study, the performance of this laser was compared with pulsed dye lasers producing pulse durations of 8 and 20 ps. Fragmentation thresholds and fragmentation rates were measured using a variety of urinary and biliary calculi. Effective fragmentation of urinary and biliary calculi was obtained with 1-ps and 8-ps pulse durations, but satisfactory fragmentation could not be achieved at 20 ps.
