New suction tools battle for best way to bust big kidney stones
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.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- 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.
