Kidney stone showdown: which procedure works best for small lower calyx stones?
NCT ID NCT07193940
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two common procedures—flexible ureteroscopy (a scope through the urinary tract) and shock wave lithotripsy (sound waves to break stones)—for treating small kidney stones (≤15 mm) located in the lower calyx. Researchers will enroll 70 adults and check which method leaves fewer stone fragments after one month. The goal is to find the safer and more effective option for these specific stones.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If this trial succeeds, it could show which procedure is more effective at clearing small kidney stones from the lower calyx, helping doctors choose the best treatment for patients.
What could go wrong
This is a small, early-stage study with only 70 participants, so results may not apply to everyone. Both procedures have risks like infection or incomplete stone removal.
