Effect of pulse width on object movement in vitro using holmium:YAG laser.

BACKGROUND AND PURPOSE The holmium:YAG laser is an effective modality for intracorporeal lithotripsy. The fiber tip needs to be in contact with the calculus for maximal effect. Laser energy can cause stone retropulsion, necessitating cumbersome repositioning of the fiber. We examined the effect of varying the laser pulse width on object movement in vitro… CONTINUE READING
