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.
