on the basis of a series of 62 children with no radiological evidence of reflux but with an abnormality of a ureterovesical implantation similar to that seen in children with radiologically detected reflux , the authors attempt to show that under certain precise conditions ( presence of cortico-papillary renal lesions , recurrent episodes of acute pyelonephritis , even in the absence of renal lesions ) , the absence of radiologically detectable reflux is not sufficient to confirm the primary nature of pyelonephritis .
