First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial tests a new way to remove kidney stones using a special laser and a flexible suction sheath. 140 adults with stones between 6mm and 20mm will be randomly assigned to get the new suction sheath or a standard sheath. The goal is to see if the new method clears more stones and causes fewer complications.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Super Pulsed Thulium Fiber Laser (sTFL) and Flexible Negative Pressure Ureteral Access Sheath
- What this could lead to
- If it works, this could offer a more effective and safer way to remove kidney stones, reducing the need for repeat procedures.
- What could go wrong
- This is a relatively small, early-stage trial. The new device may not prove significantly better than the standard sheath, and there are always risks of infection or injury during surgery.
