Battle of the scopes: which surgery best clears children's kidney stones?
NCT ID NCT07700251
First seen Jul 14, 2026 · Last updated Jul 15, 2026 · Updated 1 time
Summary
This trial compares two keyhole surgeries — retrograde intrarenal surgery (RIRS) and mini-percutaneous nephrolithotomy (mini-PCNL) — for removing kidney stones up to 2 cm in children aged 1 to 18. The goal is to see which method clears more stones with fewer complications. Both procedures are already used in adults, but their relative safety and effectiveness in children are not well established.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- two surgical procedures: retrograde intrarenal surgery (RIRS) and mini-percutaneous nephrolithotomy (mini-PCNL)
- What this could lead to
- If one procedure proves clearly safer and more effective, it could become the preferred standard for treating small-to-medium kidney stones in children.
- What could go wrong
- This is a single-center trial with only 60 children, so results may not apply broadly. Both procedures carry risks like bleeding, infection, or incomplete stone removal.
