Thereafter, SFWE was calculated using Hadlock's formula: Log10 birth weight = 1.335 - (0.0034 x abdominal circumference x femur length) + (0.0316 x biparietal diameter) + (0.0457 x abdominal circumference) + (0.1623 x femur length).20 Additionally, amniotic fluid volume
, which was measured in all four quadrants, and placental localization were recorded.
This should be followed by ultrasound scanning for basic measurements of the fetus and amniotic fluid volume
. A Doppler test of the umbilical artery should also be performed.
Practically, in several cases, there are conflicting results between colour Doppler sonography and gray-scale sonography in measurement of amniotic fluid volume
, that is, colour Doppler reports a lower or normal range for amniotic fluid volume
, but the gray-scale sonography shows significantly higher ranges for the same amniotic fluid volume

Thus, it is not entirely clear whether the adverse perinatal outcomes reflect the sequel of these conditions or reduced amniotic fluid volume
itself contributes to adverse outcomes.

in normal singleton pregnancies: modeling with quantile regression.
According to Quintero and his group, increased amniotic fluid volume
in the recipient accompanied by oligohydramnios in the donor, is associated with an increased risk for adverse outcomes.

They discuss water flux and amniotic fluid volume
in the fetus, body water changes in the fetus and newborn, electrolyte balance during normal development, normal development of the kidney, and special problems such as fetal origins of adult cardiovascular disease, renal modulation, acute problems of prematurity, lung fluid balance, edema, kidney injury, and obstructive uropathy.
