Table 3. Kidney weight and plasma renin activity in newborns.

Renal variable Group I with IUGR Group II without IUGR
Kidney weight (grams) 5.9 ±1.6 *
n = 35		 9.6 ± 2.1
n = 35
(KW/BW) X 103 2.6 ± 0.7 2.8 ± 0.6
PRA – birth (ng/ml/h) 10.5 ± 6.7†
n = 27		 8.3 ± 5.2†
n = 27
PRA – 30th day (ng/ml/h) 5.0 ± 3.7
n = 33		 4.2 ± 2.8
n = 25

IUGR = intrauterine growth restriction; PRA = plasma renin activity.

*

p < 0.001 kidney weight (newborns with IUGR versus newborns without IUGR); †p < 0.05 PRA (birth versus 30th day), in each group; (KW/BW) x103 = kidney weight/birth weight ratio x103.
