Assessment of the kidneys and urinary tract

Answer 1

• The glomerular filtration rate (GFR) is low in the newborn infant and is especially low in premature infants; the GFR at 28 weeks’ gestation is only 10% of the term infant.
• In term infants, the corrected GFR (15–20 ml/min per 1.73 m2) rapidly rises to 1–2 years of age when the adult rate of 80 to 120 ml/min per 1.73 m2 is achieved
