Summary

This study compares two types of lasers (holmium:YAG and thulium fiber) used during a minimally invasive surgery to break up large kidney stones. About 150 adults with stones larger than 15 mm will be randomly assigned to one laser or the other. The goal is to see which laser works faster and clears stones more completely.

What this could mean

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

Active substance: laser (holmium:YAG or thulium fiber)
What this could lead to: If one laser proves faster or more effective, it could become the preferred option for kidney stone surgery, reducing operation time and improving stone removal.
What could go wrong: This is a small, early-stage comparison of already-approved devices, so major breakthroughs are unlikely. Results may not apply to all patients or stone types.
