Peer Review Status: Internally Peer Reviewed
Approach/Discussion:
Normally, obtain a renal ultrasound at 10-14 days of life. Renal
ultrasounds done before that time will underestimate the amount of
hydronephrosis present because the newborn has a relatively low
glomerular filtration rate (GFR) in the first week of life.
However, if the prenatal hydronephrosis was severe and there is concern for posterior urethral valves or Prune Belly syndrome, renal ultrasound and VCUG is indicated soon after birth.
