Long-Term Efficacy and Durability of Botulinum-A Toxin for Refractory Dysfunctional Voiding in Children

Abstract

Our results demonstrate reasonable efficacy and durability of intrasphincteric botulinum toxin A injection in children with refractory dysfunctional voiding. Neuropsychiatric issues appear to negatively influence the success rate. Long-term followup is vital to identify patients in whom repeat injection may be necessary.
