Which pain block works best after kidney surgery? new trial aims to find out
NCT ID NCT06983249
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study compares two types of nerve blocks—RISS block and quadratus lumborum block—for managing pain after open nephrectomy (kidney removal). Fifty adults aged 40-70 will receive one of the two blocks. The main goal is to see which block delays the first request for extra pain medication. The results could help improve recovery and reduce reliance on opioids.
