Summary

This study compares two surgical techniques for removing kidney stones larger than 2 cm. One method uses a flexible tube with suction, and the other uses direct suction through the scope. The goal is to see which approach is faster, removes more stone, has fewer complications, and uses less fluid. About 100 adults with large kidney stones will take part.
