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.
Oligohydramnios is a condition that can develop during pregnancy. It occurs when not enough amniotic fluid, which surrounds the fetus, is produced. Oligohydramnios sequence is the pattern of abnormalities that results. Oligohydramnios sequence, or Potterâs syndrome, can cause severe abnormalities of the fetus. Not all fetuses develop abnormalities because of low levels of amniotic fluid.
