Summary

This study tested a new device called ClearPetra, which uses suction to remove kidney stone fragments during surgery, against the usual approach. Only 3 adults with kidney stones were enrolled before the study was stopped. The goal was to see if the device could clear stones better and lower infection rates, but the small size means no firm conclusions can be made.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: ClearPetra vacuum-assisted ureteral access sheath (device)
What this could lead to: If successful, this device could make kidney stone surgery faster and reduce infection risk by continuously removing stone fragments.
What could go wrong: The trial was terminated early with only 3 participants, so no reliable conclusions can be drawn. The device is new to the US market and more research is needed.
