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.

What this could lead to
If one block proves better, it could improve pain control after kidney surgery and reduce the need for strong painkillers.

This is a small, early-stage trial with only 50 participants. Results may not apply to all patients, and nerve blocks carry small risks like infection or bleeding.
