Growth of the fetal kidney. Ultrasonographic measurement of the ratio of average kidney diameter to biparietal diameter.

Kidney size was studied ultrasonographically in 101 normal fetuses. A ratio of average kidney diameter to biparietal diameter was established and found to be constant across gestation. Three fetuses with known urinary tract pathology were then studied and were found to have ratios significantly different from normal ones.

Contraction stress testing with nipple stimulation.

The contraction stress test (CST) is used widely as a measure of fetoplacental respiratory reserve. With contractions traditionally induced by intravenous oxytocin, the test has been limited in its use by time, expense and patient discomfort. In a prospective evaluation of the effectiveness of nipple stimulation for the production of uterine contractions, a successful CST was obtained in 94% of the attempts, with a mean total test time of 12 minutes.
