New pain block could make kidney stone treatment less painful
NCT ID NCT07177625
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looks at whether a retrolaminar block—a numbing injection near the spine—can reduce pain and improve comfort for people undergoing shock wave treatment for kidney stones. About 90 adults will be divided into three groups: one receiving the block, one receiving standard sedation, and one receiving no extra pain relief. Researchers will measure pain levels and the need for additional pain medication during and after the procedure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Retrolaminar block (a numbing injection near the spine)
- What this could lead to
- If it works, this could offer a safer, more effective pain relief option for people undergoing shock wave treatment for kidney stones.
- What could go wrong
- This is a small, early observational study, so results may not apply to everyone. The block may not reduce pain better than standard care and carries rare risks like infection or bleeding.
