New kidney stone surgery could be safer and more effective
NCT ID NCT07159503
First seen Jun 26, 2026 · Last updated Jun 26, 2026
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.

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.
