laser lithotripsy

Summary

Summary: Fragmentation of calculi, notably urinary or biliary, by laser. It is usually performed with an endoscopically guided pulsed tunable dye laser, a combination of a pulsed laser and a dye laser usually referred to as a pulsed dye laser. It is both safe and effective when extracorporeal shockwave lithotripsy is infeasible or unsuccessful.
