Summary

This study compares a new tool called the CVAC system, used with a special scope, to standard treatments for removing kidney stones. About 1,000 adults who need stone removal will be randomly assigned to either the new method or usual care. The main goal is to see if the new approach leaves less stone debris behind, which could reduce the need for repeat procedures.
