New nerve block could ease pain after kidney surgery
NCT ID NCT06056479
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether a specific nerve block, called an external oblique intercostal plane block, could reduce pain after kidney removal surgery. Twenty-five patients were split into two groups: one received the nerve block with a numbing medicine, and the other received morphine as needed. The goal was to see how long it took before patients needed additional pain relief and how much pain they felt.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bupivacaine
- What this could lead to
- If it works, this could offer a better way to manage pain after kidney surgery, reducing the need for strong painkillers like morphine.
- What could go wrong
- This is a very small, early study with only 25 patients, so results may not apply to everyone. The nerve block may not work as well as expected or could have side effects.
