Summary

This study compared a nerve block called an erector spinae plane (ESP) block to standard pain treatment for people with severe kidney stone pain. 24 adults took part. Researchers measured pain levels before and up to 60 minutes after treatment, and also tracked if extra pain medicine was needed. The goal was to see if the ESP block provides faster or better pain relief.
