Summary

This study tested whether stimulating nerves on one side or both sides of the body works better for people with overactive bladder that hasn't improved with standard treatments. 55 adults were randomly assigned to receive either unilateral or bilateral nerve stimulation. The goal was to see if symptoms like frequent urination and sudden urges improved by at least half after one month.
