title: Historical clues to the complex of dysfunctional voiding, urinary tract infection and vesicoureteral reflux. The International Reflux Study in Children.
abstract: The prevalence of nonneuropathic bladder/sphincter dysfunction was assessed with a questionnaire in 310 of the 386 children enrolled in the European branch of the International Reflux Study in Children. Despite the exclusion criteria (neuropathic bladder, anatomical malformations other than vesicoureteral reflux and overt dysfunctional voiding or urge incontinence), the prevalence of bladder/sphincter dysfunction was as high as 18%. Four patterns of dysfunction emerged: urge syndrome, staccato voiding, fractionated and incomplete voiding, and voiding postponement. The questionnaire proved helpful in detecting low profile cases of bladder/sphincter dysfunction, as well as indicating the need for further urodynamic studies. A strong correlation was established between recurrences of urinary tract infections, as well as disappearance of vesicoureteral reflux (negative correlation) and nonneuropathic bladder/sphincter dysfunction. This finding implies that detection and treatment of bladder/sphincter dysfunction are essential in every child with the complex of recurrent urinary tract infection and vesicoureteral reflux.
