Smaller tube, same stone removal: new kidney stone surgery tested
NCT ID NCT05088213
First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This trial compares two surgical techniques for removing kidney stones that are 2 to 4 centimeters in size. The newer method, called suction mini-PCNL, uses a smaller tube and suction to remove stone fragments, while the standard method uses a larger tube. The goal is to see if the newer method works just as well at clearing stones while causing fewer complications like bleeding and infection. The study involves 960 adults aged 18 to 70 across multiple international centers.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- suction mini percutaneous nephrolithotomy (mini-PCNL) procedure
- What this could lead to
- If successful, this could offer a safer, less invasive surgical option for removing medium-to-large kidney stones, with less bleeding and shorter hospital stays.
- What could go wrong
- This is a noninferiority trial, meaning it aims to show the new method is not worse than the standard. It may still have higher infection risk or longer surgery time.
