Holmium laser is the most used laser for lithotripsy. Holmium laser is mainly used for urological stones, but it is also used in pentacology, gynecology or dermatology. The main principle of Holmium laser lithotripsy is to use the energy generated by the laser to vaporize the water between the end of the fiber and the stone, forming a smaller bubble, which transmits energy to the stone, causing the stone to be crushed into a powder, and the water absorbs most of the energy to reduce the damage to the surrounding tissues, achieving the purpose of lithotripsy without damaging the surrounding tissues and organs, commonly used for urinary stones. Holmium laser lithotripsy is often used for the lithotripsy of urinary stones because the stones are crushed and excreted with urine.
