Summary

This study tested a new way to remove kidney stone pieces after laser treatment. Instead of using a tiny basket to grab each fragment, the SURE procedure gently vacuums them out. Researchers compared how many patients became completely stone-free with each method in 132 adults. The goal is to see if vacuuming works better at clearing all fragments.
