What is Oligohydramnios?

Oligohydramnios is the reduction of amniotic fluid that is critical for fetal urinary system development and lung maturation. Its appearance in the second trimester is more serious; it may be associated with renal agenesis or severe growth restriction.

Causes: placental insufficiency, IUGR, premature membrane rupture, fetal renal anomalies (Potter syndrome, polycystic kidney), NSAID use, and post-term pregnancy.

Complications: pulmonary hypoplasia, limb contractures (Potter facies), cord compression, intrauterine death, and fetal distress. Treatment is managed according to the underlying cause.

Symptoms

Lagging fundal height
Decreased fetal movement
Small amniotic fluid pockets on ultrasound
Bladder filling may not be visible
Meconium-stained fluid at delivery
Variable decelerations (on NST)

Risk Factors

Placental insufficiency and preeclampsia
IUGR
Post-term pregnancy (>41 weeks)
Premature membrane rupture
Fetal renal anomaly
NSAID use
