Abstract
Six lambs were delivered by caesarean section at 139 to 145 days of gestation. Birth was associated with a rise in glomerular filtration rate from 4.81 .+-. 0.62 to 5.90 .+-. 0.74 ml/min and a transient natriuresis secondary to a fall in fractional sodium reabsorption from 93.1 .+-. 3.94 to 88.3 .+-. 2.29%. This study indicates that in the immediate postnatal period, glomerulotubular balance is disturbed.
