P10. 12: Fetal renal blood flow velocimetry in patients with idiopathic oligohydramnios Academic Article uri icon


  • Objective This study was conducted to determine whether idiopatic oligohydramnios is associated with altered fetal renal artery blood flow velocimetry. Methods A prospective study was designed. Thirty six (36) pregnant women with oligohydramnios (study group) were included. The control group was composed of 28 women with normal amniotic fluid index (AFI). All patients had intact membranes at 24–40 weeks gestation. Fetuses with congenital anomalies and small for gestational age fetuses were excluded. Oligohydramnios was defined as AFI of less than the 5th percentile for gestational age (Moore, 1997). Velocity waveforms of the renal artery were recorded and pulsatility index (PI) values were calculated. PI of more than the 95th percentile for gestational age was considered abnormal. Perinatal outcome was compared between the groups, including …
