Which procedure wins for kidney stones in oddly shaped kidneys?
NCT ID NCT05240170
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This trial compares two ways to treat kidney stones in people whose kidneys are shaped or positioned abnormally from birth. One method, retrograde intrarenal surgery (RIRS), uses a thin scope passed through the urinary tract to break up stones with a laser. The other, shockwave lithotripsy (SWL), sends shock waves from outside the body to shatter stones. The study will see which approach clears more stones completely, with fewer complications and less need for repeat treatment.
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 are compared: retrograde intrarenal surgery (RIRS), using a flexible scope and laser to break up stones, and extracorporeal shockwave lithotripsy (SWL), which uses shock waves from outside the body to fragment stones.
- What this could lead to
- If RIRS proves more effective, it could become the preferred treatment for kidney stones in people with congenital kidney anomalies, improving stone clearance and reducing the need for repeat procedures.
- What could go wrong
- This is a single-center study, and results may not apply to all patients. RIRS is more invasive and carries risks like bleeding or infection, while SWL may be less effective for certain stone types.
