Summary

This study will compare two types of tubes (ureteral access sheaths) used during kidney stone surgery to see if one causes less kidney damage. Sixty adults with kidney stones will be randomly assigned to get either the standard tube or a new aspiration-assisted tube. Doctors will use a special ultrasound technique called shear-wave elastography to measure kidney stiffness before surgery, one day after, and seven days after, which can indicate tissue damage.

What this could mean

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

Active substance: Aspiration-assisted ureteral access sheath versus standard ureteral access sheath
What this could lead to: If successful, this could help surgeons choose a safer device for kidney stone surgery, potentially reducing kidney damage.
What could go wrong: This is a small, early-stage study (60 participants) that only measures short-term changes. It may not show clear differences or apply to all patients.
