Abstract
The cases of abnormal volume of amniotic fluid experienced in our hospital were evaluated together with their neonatal diseases. Since it is thus clear that there is a distinct relationship between fetal anomalies and abnormalities in the volume of amniotic fluid, it is urgently required to approach positively toward prenatal diagnosis of congenital anomaly. In particular, it is expected that definition and prenatal diagnosis of oligoamnions be clarified as early as possible.
