Oligohydramnios in the first trimester refers to a condition where there is an abnormally low amount of amniotic fluid surrounding the developing fetus. This can indicate potential issues such as fetal kidney problems, urinary tract abnormalities, or placental insufficiency. Early detection is crucial, as it may lead to further investigations and monitoring to ensure the health of both the fetus and the mother. However, isolated cases of oligohydramnios in early pregnancy may resolve on their own as the pregnancy progresses.
Oligohydramnios in the first trimester can be caused by several factors, including fetal anomalies, such as renal agenesis or urinary tract obstructions, which impair urine production. Maternal conditions, such as dehydration or certain medications, can also contribute to low amniotic fluid levels. Additionally, issues with the placenta, such as placental insufficiency, may affect fluid dynamics. Early rupture of membranes can be another cause, although it's more common later in pregnancy.
Oligohydramnios usually associated with absence of both kidneys
