Isolated polyhydramnios is traditionally defined as polyhydramnios in the absence of congenital anomalies (especially of the central nervous, cardiac or gastrointestinal system), maternal diabetes, fetal infection, placental tumors, or multiple gestation,and accounts for 50-60 % of polyhydramnios cases. Up to one quarter of presumed isolated polyhydramnios cases are diagnosed with an abnormality in the postpartum period. Although considered isolated, idiopathic polyhydramnios was found to be associated with adverse outcomes such as increased risk for fetal macrosomia, caesarean delivery (CD), or assisted vaginal delivery (AVD) and an increased risk of perinatal morbidity and mortality. Transient isolated polyhydramnios (TIP) is defined as polyhydramnios diagnosed during gestation, which later resolves. The question remains as to whether transient isolated polyhydramnios has a clinical impact on pregnancy outcomes.
