Abstract

Pulsed-dye-laser fragmentation of biliary and urinary calculi is associated with a bright flash, an acoustic transient and material removal. Time-resolved spectroscopic studies of the flash have demonstrated the presence of a plasma when fragmentation occurs. A model is proposed in which the plasma absorbs the optical energy of the laser, and expands, and generates mechanical forces that fragment the stone.
