Uroflowmetry in neurologically normal children with voiding disorders.

A prospective study was undertaken to delineate the role of spontaneous uroflowmetry as screening procedure for functional infravesical obstruction (detrusor/sphincter dyssynergia). More than 70% of thirty-nine children referred for urinary tract infections and/or enuresis in the absence of neurological deficits underwent a complete diagnostic program including intravenous urography, voiding cystography and cystoscopy as well as spontaneous uroflowmetry, cystometry-emg and pressure-flow-emg study. The incidence of dyssynergia was 22%. However, neither the flow curve pattern nor single flow variables were able to identify children with dyssynergia. Consequently uroflowmetry seems inefficient in the screening for dyssynergia in neurological normal children with voiding disorders in the absence of anatomical bladder outlet obstruction.
