New laser may zap kidney stones faster and safer
NCT ID NCT06667557
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study compares two types of lasers used to break up kidney stones during a minimally invasive procedure called ureteroscopy. One laser uses a superpulse thulium fiber (sTFL), the other is a standard holmium laser. Researchers will enroll 136 adults aged 18–70 with kidney stones 6–20 mm in size. The main goal is to see which laser clears more stones after 3 months, and which causes fewer complications or shorter surgery times.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Superpulse thulium fiber laser (sTFL) and holmium:YAG laser (Ho:YAG) — both used as surgical devices to break up kidney stones during ureteroscopy.
What this could lead to
If sTFL proves better, it could become the preferred laser for kidney stone surgery, offering higher stone clearance and fewer complications.
What could go wrong
This is a relatively small trial (136 people) comparing two established techniques. Even if sTFL shows advantages, the difference may be modest and not change practice widely.
