INCREASED RENAL MEDULLARY ECHOGENICITY IN NEONATES

The prevalence of increased renal medullary echogenicity in healthy ne onates was looked for. A group of 178 neonates underwent renal ultraso und on the first and second days of life. On the first day of life 58 % had hypereochoic material in their renal collecting system, whereas on the second day only 33 % were found to have ultrasonographically de monstrable increased echogenicity in their kidneys. Urinary protein co ncentrations in infants with increased renal echogenicity were signifi cantly higher than in those without increased renal echogenicity.
