Summary

This study compares a new surgical tool called VISOR to a standard scope for removing kidney stones. VISOR combines suction, pressure control, and laser to break up and remove stones in one step. About 100 adults with stones up to 3 cm will be randomly assigned to get either VISOR or standard surgery. The main goal is to see if VISOR leaves fewer stone fragments right after surgery and at 3 months, while keeping the kidney safe.

What this could mean

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

Active substance: VISOR system (a surgical device that suctions stones and controls pressure during ureteroscopy)
What this could lead to: If it works, this could mean fewer leftover stone fragments and fewer complications for people undergoing kidney stone surgery.
What could go wrong: This is a small, early-stage trial with only 100 people, so results may not apply to everyone. The new device could also cause unexpected side effects like injury or infection.
