Can two kidney stone blasts in one week be as safe as waiting three weeks?
NCT ID NCT07421843
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two schedules for shockwave lithotripsy (ESWL) to treat kidney stones 8-15 mm. 600 participants will receive two ESWL treatments either in the same week or three weeks apart. Researchers will measure how quickly stones clear, complication rates, and patient quality of life to see if the faster schedule is equally safe and effective.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Extracorporeal shockwave lithotripsy (ESWL)
What this could lead to
If it works, this could offer a faster, equally safe way to break up kidney stones, reducing the time patients need to wait between treatments.
What could go wrong
This is a small, early-stage trial with no blinding or placebo, so results may not apply broadly. There is also a risk of complications like bruising or incomplete stone clearance.
