About this study

This cross-sectional study occurred in a tertiary center with volunteer pregnant women who agreed to drink coffee. In healthy pregnant women with isolated borderline oligohydramnios, AFI and fetal renal artery blood flow indices were evaluated before and after coffee consumption. Sixty three patients for the borderline oligohydramnios group (the study group) were included in this study. These patients were compared with 63 healthy pregnant women who had normal amniotic fluid volume (the control group)
