Which procedure wins for dense kidney stones?
NCT ID NCT04346134
First seen Aug 12, 2026 · Last updated Aug 14, 2026 · Updated 2 times
Summary
This trial compares two procedures for treating hard, medium-sized kidney stones (10-20 mm) that are not in the lower pole of the kidney. One is mini-PNL, a minimally invasive surgery, and the other is SWL, which uses shock waves to break up stones. The study will randomly assign 72 adults to one of the two procedures and track how completely the stones are cleared and any complications over three months.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Two procedures: miniaturized percutaneous nephrolithotomy (mini-PNL) and extracorporeal shock wave lithotripsy (SWL)
- What this could lead to
- If one procedure proves safer and more effective, it could become the preferred standard for treating medium-sized, dense kidney stones, reducing the need for repeat treatments.
- What could go wrong
- This is a single study with 72 participants, so results may not apply to everyone. Both procedures carry risks like bleeding, infection, or incomplete stone removal.
