Shock vs. pill: which works best for Kids' bladder issues?
NCT ID NCT07030803
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two treatments for children with overactive bladder (OAB) of unknown cause: the standard medication oxybutynin and a nerve stimulation therapy (PTNS). About 124 children aged 6 to 16 will be randomly assigned to one treatment for three months. The goal is to see if the nerve stimulation is as good as the medication at reducing symptoms like frequent urination and leakage.
