One cut or many? a surgical showdown for complex kidney stones
NCT ID NCT07753733
First seen Aug 07, 2026 · Last updated Aug 14, 2026 · Updated 3 times
Summary
This trial compares two surgical techniques for removing complex kidney stones: a single-tract approach using a flexible scope versus the traditional multi-tract method. The goal is to see if the less invasive single-tract procedure can achieve similar stone-free rates at three months while potentially reducing complications. Adults aged 18-70 with complex unilateral kidney stones are eligible to participate.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Flexible Nephroscopy-Assisted Single-Tract PCNL (a surgical procedure using a single access point with a flexible scope) compared to Conventional Multi-Tract PCNL (a surgical procedure using multiple access points with a rigid scope)
- What this could lead to
- If successful, this could establish a less invasive surgical option for complex kidney stones, potentially reducing bleeding and hospital stays while maintaining similar stone removal rates.
- What could go wrong
- The single-tract approach might not clear all stones as effectively as multiple tracts, and the trial's results depend on surgeon skill and patient anatomy. Complications like bleeding or infection are possible with any kidney stone surgery.
