NCT ID NCT07342361

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study compares a new bendable tip-suction ureteral access sheath to a standard one during surgery for large kidney stones (staghorn stones). About 100 adults will be randomly assigned to one of the two sheaths. The goal is to see if the new sheath reduces complications and clears more stones, as checked by CT scans after surgery.

What this could lead to

If successful, this could make surgery for large kidney stones safer and more effective, reducing complications and improving stone removal rates.
