Abstract

• Objectives
  The relation between clinically obvious polyhydramnios and poor perinataloutcome has been described. The purpose of the present investigation was to relate polyhydramnios to etiology and perinatal outcome.
• Methods
  Mild and severe polyhydramnios was defined sonographically as an amnioticfluid index of 240~300, and more than 300 respectively. We diagnosed polyhydramnios in 16 cases of 3160 patients(0.5%) undergoing fetal testing at 26-42 gestational weeks. We compared mild and severe polyhydramnios in aspect of perinatal outcome.
• Results
  The severe polyhydramnios group showed a significantly higher incidence of neonatal death and associated congenital anomaly than mild polyhydramnios group.
• Conclusion
  We conclude that severe polyhydramnios is associated with an increased risk of adverse perinatal outcome.
