Local Injection of Botulinium Toxin-A in Children With Dysfunctional Voiding or Refractory Nocturnal Eneuresis

April 5, 2026 updated by: Ahmad Mohamed Elsaied Shalaby, Tanta University

Evaluation of Local Injection of Botulinium Toxin-A in Children With Dysfunctional Voiding or Refractory Nocturnal Eneuresis

The aim of this study is to evaluate the outcome of botulinum toxin A (BTX-A) injection for management of children with :

A-Dysfunctional voiding who are not responding to traditional treatment. B-Refractory nocturnal enuresis.

Study Overview

Detailed Description

Dysfunctional voiding (DV) is a habitual voiding disorder caused by involuntary contraction or non relaxation of the external urethral sphincter (EUS) during voiding.

This contraction causes high post void residuals (PVR), The disorder can occur at any age. In young children it often presents as urinary incontinence, nocturnal enuresis, or recurrent urinary tract infections (UTIs).

Nocturnal enuresis (NE) is common, affecting 15-20 % of children by five years old, and 8-10 % of children by eight years old.

Refractory nocturnal enuresis is defined as monosymptomatic nocturnal enuresis (bedwetting without daytime urinary symptoms) that persists despite at least 3-6 months of appropriate and compliant first line therapy.

Botulinum toxin has been found to inhibit the release of a number of neurotransmitters (including acetylcholine, adenosine triphosphate, and neuropeptides such as substance P) and to down regulate the expression of purinergic and capsaicin receptors on afferent neurons within the bladder.
