The diagnosis of oligohydramnios during pregnancy is established on the basis of data obtained as a result of a patient interview and an objective examination conducted by an obstetrician-gynecologist. A number of laboratory tests and instrumental studies are also prescribed. It is possible to suspect oligohydramnios during pregnancy during a routine examination of a woman. The characteristic signs of an insufficient volume of OPV will be a discrepancy between the circumference of the abdomen and the height of the fundus of the uterus and the gestational age with a downward deviation. At the same time, it is important to carefully collect an anamnesis and establish the probable cause of this condition, since the subsequent treatment tactics depend on it.
To exclude an infectious factor in the formation of oligohydramnios during pregnancy, laboratory tests of urine and blood are prescribed. The sampling of smears from the genital tract is shown in order to determine the pathogenic microflora and exclude or confirm the suspicion of its introduction to the fetus. It is possible to finally confirm oligohydramnios during pregnancy with the help of ultrasound. During the examination, the specialist accurately determines the volume of OPV, assesses the condition of the placenta and the child, and identifies congenital anomalies that could contribute to the development of this pathological condition. Also, oligohydramnios during pregnancy involves a CTG to determine the well-being of the child.
