OBJECTIVE: To evaluate the incidence of side-effects of oral and intravesical oxybutynin chloride in children with meningomyelocele (MMC) and a neurogenic bladder. PATIENTS AND METHODS: The study comprised 225 children with a neurogenic bladder from MMC who were evaluated with urodynamic testing and voiding cysto-urethrography to identify those at high risk of upper tract damage. In all, 101 children (mean age 4.2 years, range 0.25-10) had unco-ordinated detrusor-sphincter function and low compliance; they were treated with either oral or intravesical oxybutynin and clean intermittent catheterization. RESULTS: Of the 101 patients, 67 were treated with oral oxybutynin; in 11 the treatment was discontinued because of the side-effects. The other 34 patients used both clean intermittent catheterization and intravesical oxybutynin. In this group there were side-effects in six patients, including drowsiness, hallucinations and cognitive changes. CONCLUSIONS: Oral and intravesical oxybutynin is effective for managing neurogenic bladder dysfunction, but intravesical administration is safer and better tolerated than oral oxybutynin in the treatment of children with MMC. However, adverse effects such as cognitive impairment can also occur in children treated with intravesical oxybutynin and these patients must be closely monitored because these effects may differ from those with oral administration.
