Kidney stone surgery simplified: catheter may be unnecessary
NCT ID NCT06750913
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a common step in kidney stone surgery—placing a tube from the bladder to the kidney—can be skipped. 140 adults with large kidney stones were randomly assigned to get the standard surgery or a version without the tube. The goal was to see if the simpler method is safe and effective, potentially making surgery faster and reducing infection risk.
