NCT ID NCT07087977

First seen May 12, 2026 · Last updated May 15, 2026 · Updated 2 times

Summary

This study compares two FDA-approved lasers (Holmium:YAG with MOSES and thulium fiber) for breaking large kidney stones during a minimally invasive surgery called mini-PCNL. About 150 adults with stones larger than 15mm will be randomly assigned to one laser, both using a suction sheath to help remove fragments. The goal is to see which laser reduces surgery time and clears stones better.
