In vitro effects of pulsed holmium laser energy on canine uroliths and porcine cadaveric urethra.

Background And Objectives: To assess the effect of holmium laser energy on canine uroliths and porcine urethra.

Study Design/materials And Methods: Uroliths of known composition and fresh cadaveric urethra were exposed to holmium laser energy. Urolith fragmentation times and depth of urethral lesions were determined.
