Oligohydramnios is a medical condition in pregnancy characterized by a deficiency of amniotic fluid, the fluid that surrounds the fetus in the abdomen, in the amniotic sac. The limiting case is anhydramnios , where there is a complete absence of amniotic fluid.
Oligohydramnios is the cause of Potter sequence, but there are many things that can lead to oligohydramnios. It can be caused by renal diseases such as bilateral renal agenesis (BRA), atresia of the ureter or urethra causing obstruction of the urinary tract, polycystic or multicystic kidney diseases, renal hypoplasia , amniotic rupture ...
Amnion nodosum is a placental hallmark of severe and prolonged oligohydramnios, and it is associated with a high risk of fetal and perinatal mortality. The cause and pathophysiology of nodule formation in Amnion nodosum are largely unknown.
Post-maturity syndrome is the condition of a baby born after a post-term pregnancy, first described by Stewart H. Clifford in 1954. [1] Post-maturity refers to any baby born after 42 weeks gestation, or 294 days past the first day of the mother's last menstrual period.
Twin-to-twin transfusion syndrome (TTTS), also known as feto-fetal transfusion syndrome (FFTS), twin oligohydramnios-polyhydramnios sequence (TOPS) and stuck twin syndrome, is a complication of monochorionic multiple pregnancies (the most common form of identical twin pregnancy) in which there is disproportionate blood supply between the fetuses.

Bartter syndrome (BS) is a rare inherited disease characterised by a defect in the thick ascending limb of the loop of Henle, which results in low potassium levels (hypokalemia), [2] increased blood pH , and normal to low blood pressure. There are two types of Bartter syndrome: neonatal and classic.
Adults with unilateral renal agenesis have considerably higher chances of hypertension (high blood pressure). People with this condition are advised [ 7 ] to approach contact sports with caution. A possible complication later in life of unilateral renal agenesis is focal segmental glomerular sclerosis (FSGS) which will cause nephrotic syndrome ...
