Non-neurogenic bladder dysfunction and vesicoureteral reflux in children

Various types of bladder dysfunction are associated with urinary tract infection, renal damage and vesicoureteral reflux (VUR). In this article the influence of functional bladder disturbances such as detrusor instability (overactive bladder, OAB) and bladder sphincter dyssynergia (dysfunctional voiding), on the resolution of vesicoureteral reflux are reviewed. In summary, it is important to distinguish between children with dysfunctional voiding (increased activity of the pelvic floor during voiding) and those with OAB (detrusor overactivity during filling) because the latter has less effects on VUR.
