Pathophysiology. Rupture of the membranes is the most common cause of oligohydramnios. However, because the amniotic fluid is primarily fetal urine in the latter half of the pregnancy, the absence of fetal urine production or a blockage in the fetus' urinary tract can also result in oligohydramnios.
What is the remedy? A. Oligohydramnios or oligoamnios is a deficiency in the amount of amniotic fluid. This fluid bathes the fetus in the uterus and is necessary for its proper growth and development. It cushions the fetus from physical trauma, permits fetal lung growth, and provides a barrier against infection.
