Nerve block may slash opioid use after kidney surgery

NCT ID NCT07704970

First seen Jul 15, 2026 · Last updated Jul 17, 2026 · Updated 2 times

Summary

This trial tests whether an ultrasound-guided nerve block called QLESP can reduce pain and the need for opioid painkillers after robot-assisted partial nephrectomy for kidney cancer. Adults scheduled for this surgery are randomly assigned to receive either the QLESP block or a standard numbing injection at the surgical wounds. Pain scores and opioid use are tracked for 72 hours after surgery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
ropivacaine given as a nerve block (QLESP) or local wound injection
What this could lead to
If it works, this could offer a better way to control pain and reduce reliance on strong opioids after kidney surgery.
What could go wrong
This is a single-center trial with 120 participants, so results may not apply to all hospitals or patients. The nerve block carries small risks like infection or bleeding.
