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.
This outcome is postulated to result from expression of the polycystic kidney and hepatic disease gene PKHD1, which is located on chromosome 6p. [9] In severe cases, a fetus will present with oligohydramnios and as a result, may present with Potter sequence. [10]
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 ...
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 ...
Serville et al. (1989) demonstrated the feasibility of ultrasonographic diagnosis of the Fraser syndrome at 18 weeks' gestation. They suggested that the diagnosis could be made if 2 of the following signs are present: obstructive uropathy, microphthalmia, syndactyly, and oligohydramnios. Schauer et al. (1990) made the diagnosis at 18.5 weeks ...
The symptoms of hyperthyroidism tend to arise in a few different areas of the body, and because they often resemble that of other health concerns, an official diagnosis should always come from ...
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.
