New vacuum tool may improve kidney stone surgery
NCT ID NCT05993546
First seen Jun 25, 2026 · Last updated Jun 30, 2026 · Updated 3 times
Summary
This study compares two surgical methods for removing kidney stones: one using a vacuum-assisted sheath and the other using a standard sheath. About 90 adults with stones between 10-25 mm will be randomly assigned to one of the two procedures. The goal is to see which method clears stones more completely and leads to better recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- vacuum-assisted access sheath (device)
- What this could lead to
- If successful, this could show that vacuum-assisted sheaths remove kidney stones more completely and with fewer complications than standard sheaths.
- What could go wrong
- This is a small, early-stage trial with only 90 participants, so results may not apply to everyone. Both methods are already used, so the difference may be small.
