Summary

This study looked at 98 adults who had kidney removal surgery to see which pain-blocking method works better: a paravertebral block or an external oblique intercostal block. Both are injections that numb nerves to reduce pain after surgery. The goal was to find which one leads to less pain and fewer side effects.
