Laser lithotripsy. Laser lithotripsy is a surgical procedure to remove stones from urinary tract, i.e., kidney, ureter, bladder, or urethra.
Laser lithotripsy was introduced in the 1980s. Pulsed dye lasers emit 504 nm light that is delivered to the stone by optical fibers through a scope. Holmium lasers were developed more recently and produce smaller fragments.
