title: A sonographic assessment of neonatal renal parameters.
abstract: One hundred twenty infants ranging in weight from 600 to 4,000 grams were entered into a prospective sonographic study to establish normal renal growth parameters. Renal cortical echogenicity was demonstrated to decrease with increasing infant weight. Observations on the use of Doppler analysis for assessing renal vascular flow are presented.
