oligohydramnios
Oligohydramnios is a severe and common complication of pregnancy. The finding of oligohydramnios can be associated with fetal anomalies, PROM, uteroplacental insufficiency (eg, growth retardation, postdatism, abruptio placenta, significant maternal illness), abnormalities of twinning, and idiopathic oligohydramnios.
Synopsis
oligohydramnios sequence
Etiology
rupture of amniotic membranes (ROM)
- preterm premature rupture of the fetal membranes
chronic leakage of amniotic fluid
fetal anuria and fetal oliguria
- renal oligohydramnios
- bilateral renal agenesis
- autosomal recessive polycystic kidney disease (ARPKD)
- renal tubular dysgenesis (#11156331#)
- congenital absence of functional renal tissue or obstructive uropathy
- urinary tract malformations
- bilateral renal agenesis
- bilateral renal dysplasia (BRD)
- urethral atresia (urthral obstruction sequence, UOS)
decreased renal perfusion with chronic reduction in fetal urine production
- hypoxemia-induced redistribution of fetal cardiac output
- growth-restricted fetuses
- fetal chronic hypoxia with shunting of fetal blood from the kidneys to vital organs
post-term gestation
twin-twin transfusion syndrome
tracheal atresia and tracheal atresia sequence (TAS)
laryngeal atresia and laryngeal atresia sequence (LAS)
uteroplacental insufficiency
- growth retardation
- postdatism
- abruptio placenta
- significant maternal illness
