What this trial studies

This clinical trial investigates the efficacy and safety of high-dose vitamin D (2400iu daily) combined with standard behavioral therapy in treating children with wet overactive bladder (OAB). It compares this approach to standard behavioral therapy alone and to a combination of behavioral therapy with solifenacin medication. The study aims to assess improvements in urinary incontinence frequency and lower urinary tract symptoms, while also exploring the relationship between vitamin D levels and these symptoms. Participants will be randomized into three groups to evaluate the effectiveness and safety of the interventions.

Who should consider this trial

Good fit: Ideal candidates are children aged 5 and older diagnosed with wet OAB and having low serum vitamin D levels.

Not a fit: Patients with urinary malformations, serious diseases, or neurological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option that improves urinary incontinence and quality of life for children with wet OAB.

How similar studies have performed: While the combination of vitamin D with behavioral therapy is a novel approach, previous studies have shown potential benefits of vitamin D in various conditions, suggesting a promising avenue for exploration.
