NCT ID NCT04997668
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared two FDA-approved lasers used to break up kidney stones during surgery: the newer SOLTIVE Thulium Fiber Laser and the standard Ho:YAG laser. About 100 adults with a single stone smaller than 2 cm took part. Researchers measured how well each laser cleared stones, how long surgery took, and how satisfied surgeons were.

- Active substance
- SOLTIVE Thulium Fiber Laser (device) compared to Ho:YAG laser (device)
- What this could lead to
- If SOLTIVE works better, it could make kidney stone surgery faster and more efficient, with similar success rates.
- What could go wrong
- This is a small, completed trial with only 100 participants. The new laser may not be significantly better than the standard one.
