NCT ID NCT07559214
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This trial will compare two techniques for removing kidney stones larger than 2 cm: a flexible suction sheath (FANS) and direct suction through the scope (DISS). About 100 adults will be randomly assigned to one method. The study will measure surgery time, how completely stones are removed, complications, and fluid use.

Active substance
Flexible and Navigable Access Sheath (FANS) and Direct In-Scope Suction (DISS) procedures
What this could lead to
If one method proves faster and safer, it could become the preferred technique for removing large kidney stones, reducing surgery time and complications.
What could go wrong
This is a small, early-stage trial that has not yet started recruiting. The results may not apply to all patients, and both procedures carry standard surgical risks like infection or injury.
