New study tests suction tools to improve kidney stone removal
NCT ID NCT07516535
First seen Apr 16, 2026 · Last updated Jun 21, 2026 · Updated 11 times
Summary
This study compares two suction-assisted techniques used during kidney stone surgery: Direct In-Scope Suction (DISS) and Flexible and Navigable Suction Ureteric Access Sheath (FANS). The goal is to see which method better clears stones and reduces infections after surgery. About 126 adults with medium-sized kidney stones (2-3 cm) will be randomly assigned to one of the two techniques. The results could help surgeons choose the best approach for this common condition.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Suction-assisted surgical techniques (Direct In-Scope Suction and Flexible and Navigable Suction Ureteric Access Sheath)
What this could lead to
If one technique proves better, it could become the preferred method for removing medium-sized kidney stones, leading to fewer infections and more complete stone clearance.
What could go wrong
This is a small, early-stage trial with only 126 participants, so results may not apply to everyone. Both techniques are surgical procedures with inherent risks like infection or injury.
