deepest pocket (SDP) assessment which is also referred to as the modified BPP. Sonographic fetal growth exams may also be indicated. Timing of delivery Idiopathic, uncomplicated, and persistent oligohydramnios can be delivered at 36 0/7 weeks – 37 6/7 weeks of gestation or at diagnosis if diagnosis is later. Complications Complications may include cord compression, musculoskeletal abnormalities such as facial distortion and clubfoot, pulmonary hypoplasia and intrauterine growth restriction. Amnion nodosum is frequently also present (nodules on the fetal surface of the amnion). The use of oligohydramnios as a predictor of gestational complications is controversial. Potter syndrome is a condition caused by oligohydramnios. Affected fetuses develop pulmonary hypoplasia, limb deformities, and characteristic facies. Bilateral agenesis of the fetal kidneys is the most common cause due to the lack of fetal urine.
