Summary

This study compares lidocaine, a numbing drug, to morphine for treating severe kidney stone pain in the emergency room. Researchers will enroll 250 adults whose pain isn't relieved by standard treatment. The goal is to see if lidocaine provides better pain relief at 30 minutes, potentially offering a safer, non-opioid option.
