Summary

This study tests whether giving a water pill (furosemide) and extra fluids during laser kidney stone surgery helps clear out tiny leftover fragments. About 374 adults who need this surgery will be randomly assigned to receive either the water pill plus fluids or standard care. Three months later, a CT scan will check if more patients are completely stone-free in the treatment group.
