title: Variations in vesicoureteral reflux. Influence on diagnostic validity.
abstract: Micturition cystourethrography was performed with varying numbers of films exposed and the probability of missing a vesicoureteral reflux or underrating its severity was calculated for each series. It was concluded that a small number of exposures can give sufficiently accurate diagnosis.
