Summary

This study compares two different laser power settings (high pulse vs low pulse) during a minimally invasive surgery called mini-PCNL to remove large kidney stones (over 20 mm). About 70 adults will be randomly assigned to one of the two laser settings. The goal is to see which setting is safer and more effective at breaking up stones, with less complications and better stone clearance after three months.
