Summary

This study tests whether adding high-dose vitamin D to standard care helps children with overactive bladder (wet) reach their goal of zero leakage. About 180 children aged 5 and older with low vitamin D levels will receive either standard treatment alone or standard treatment plus daily vitamin D for 12 weeks. Researchers will track symptoms, nerve repair markers, and family costs to see if the combination works better.
