Summary

This trial tests whether a new flexible and navigable suction ureteral access sheath (FANS) works better than the standard sheath for removing kidney stones smaller than 2 cm in children. Sixty children will be randomly assigned to one of the two devices during a procedure called flexible ureterorenoscopy. The study measures how many stones are completely removed, how long the surgery takes, and any complications.

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 Suction Ureteral Access Sheath (FANS)
What this could lead to: If successful, this could offer a safer, more effective way to remove kidney stones in children, reducing the need for repeat procedures.
What could go wrong: This is a small, early-stage trial with only 60 children, so results may not apply to all patients. The new device may not improve outcomes and could carry unknown risks.
