Summary

This trial tests a new device called VISOR for removing kidney stones. It combines stone breaking, suction, and pressure control in one tool. About 20 adults with 1-3 cm stones will undergo surgery with VISOR. The goal is to see if it clears stones safely and effectively, with a CT scan within 24 hours and a follow-up at one month.
