Summary

This study compared two surgical methods for removing kidney stones between 2 and 4 centimeters: flexible ureteroscopy (a less invasive scope through the urinary tract) and percutaneous nephrolithotomy (a small incision in the back). The goal was to see if the less invasive option works as well at clearing stones. The trial planned to include 224 adults aged 18-70, but it was terminated early, so the full results are not available.

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 successful, this could show that the less invasive ureteroscopy works as well as standard surgery for medium-to-large kidney stones, giving patients a safer option.
What could go wrong: The trial was terminated early, so results may be incomplete. Both procedures carry risks like infection or bleeding, and individual outcomes vary.
