Applicability of botulinum toxin type A in paediatric neurogenic bladder management

Purpose of review: The purpose of this article is to provide an overview about the applicability of botulinum toxin type A (BTX-A) in paediatric neurogenic bladder based on the recently published literature combined with hypothetical notes and future perspectives. Recent findings: The indications, clinical outcomes, urodynamic outcome parameters and cost-effectiveness are presented from recent publications. Also, alternative routes of application of BTX-A in the bladder are discussed as well as the influence of BTX-A on conservative and invasive treatment. Summary: Intradetrusor BTX-A injections for neurogenic bladder dysfunction are effective in resolving both urinary incontinence and improving urodynamic parameters in most children with a sustained response at repeated injections. In low-compliance bladders, however, if no response is seen after initial BTX-A injection, repeated injections seem to be unnecessary. Because general anaesthesia is mandatory for BTX-A injections in children, alternative routes of application have been investigated such as intravesical installation, electromotive drug application and liposomal drug delivery; however, no definite results have been found in a paediatric clinical setting.
