New pain block after kidney stone surgery could cut opioid use
NCT ID NCT05121168
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a continuous nerve block (using the numbing medicine bupivacaine) can reduce pain and opioid use after kidney stone surgery. Fifty adults having surgery received a single nerve block plus a catheter, then were randomly given either more numbing medicine or a placebo (salt water) for two days. The goal was to see if the continuous block improves pain scores and lowers opioid consumption compared to a single injection alone.

What this could lead to
If it works, this could offer a better way to manage pain after kidney stone surgery, reducing the need for opioids.
