“…This reflects the rapidly increasing urine volumes in the first week of life [9], A renal involvement is shown to take place in infants with IRDS, causing decreased filtration rate and urine flow [I], In asphyxiated newborn infants proteinuria and cylindruria in considerable amounts are frequently found [3], The uromucoid concentration in urine in infants with IRDS and asphyxia were, however, in the present investi gation not different from the concentrations in healthy newborn infants. Neither did gestational age (30-42weeks) correlate to uromucoid concentration in urine.…”

Uromucoid (Tamm-HorsfalΓs mucoprotein) was not detected in amniotic fluid from pregnancies with gestational age 12–18 weeks, but was detected in 5 of 9 samples of amniotic fluid from full-term pregnancies, and in urine from all full-term infants investigated 1st day of life. This suggests that uromucoid excretion under normal conditions esthablished near term. Change from intrauterine to extrauterine life may rapidly induce uromucoid excretion, as this protein was found in premature infants (32–34 weeks of gestation) at the 2nd day of life. Healthy newborn infants had a lower uromucoid concentration in urine than children 7–13 years old. In newborns with uncomplicated prematurity, idiopathic respiratory distress syndrome and full-term asphyxiated newborns, the uromucoid concentration in urine during the 1st week of life was not different from healthy newborn infants. Though uromucoid is found to be the major constituent of hyaline casts, the excretion of casts did not correlate to the uromucoid concentration.

“…Previous studies have described the variations in urinary flow rate and concentration during the first few days of postnatal life [1,2]. However, these data were obtained from infants who were thirsted or fasted for an extended time after birth.…”

“…This mechanism of water conservation is comparable to that of the adult. Measurements of osmotic pressure and of specific gravity have not given a true evaluation of water conservation in infants (21)(22)(23) for water reabsorption by the tubules of the premature infant's kidney conflicts with the finding of Heller (24) that the tubules are relatively insensitive to pitressin. We have, in a preliminary way, put this to the test by more crucial observations than those employed by Heller.…”
