This study will evaluate the safety and effectiveness of an anticholinergic drug treatment administered by transdermal patch to treat overactive bladder in children who have a neurological condition (e.g. spina bifida) that contributes to their overactive bladder.

This study will use a multicenter, randomized, open-label, active-controlled, dose-titration, parallel group design, in approximately pediatric patients with detrusor overactivity associated with a neurological condition.

Inclusion Criteria:

• Pediatric patient with a diagnosis of detrusor overactivity associated with a neurological condition;
• Use clean intermittent catheterization
• On stable dose of oral oxybutynin before participation

Exclusion Criteria:

• Have one or more treatable conditions, other than neurogenic bladder dysfunction, that may cause urinary incontinence or urgency
• Have any medical condition that precludes their participation in the study or may confound the outcome of the study
