Summary

This study tests a new procedure called VISOR against the standard surgery (PCNL) for removing kidney stones that are 2 to 4 centimeters in size. About 170 adults will be randomly assigned to one of the two surgeries. The main goal is to see how many people are stone-free within 24 hours and at one month after surgery, and to compare side effects like fever or injury.

What this could mean

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

Active substance: Vortex Intelligence Stone Optimized Removal (VISOR) procedure
What this could lead to: If successful, VISOR could offer a safer and more effective way to remove medium-sized kidney stones, reducing complications and improving recovery.
What could go wrong: This is a relatively early study with 170 participants, so results may not apply to everyone. The new procedure might not be better than the standard surgery and could have unexpected risks.
