Summary

This study compares two types of lasers used to break up kidney stones during a procedure called ureteroscopy. About 136 adults aged 18–70 with kidney stones will be randomly assigned to receive either the new superpulse thulium fiber laser or the standard holmium laser. The goal is to see which laser clears stones more completely, has fewer side effects, and is easier for surgeons to use.
