Doppler Study of the Fetal Renal Artery in Oligohydramnios with Post-term Pregnancy

Conclusion In oligohydramnios in the context of post-term pregnancies, there is an increased resistance in the fetal renal vascular bed. The reduced FRABF suggests that increased arterial impedance is an important factor in the development of oligohydramnios. This study supports the idea of increased vascular resistance in the fetal renal bed in patients in post-term pregnancies. We think that fetal renal artery Doppler measurement should be part of a routine daily clinical obstetric practice in post-term pregnancies with oligohydramnios.
