Potter syndrome is a congenital birth defect. Specifically, Potter Syndrome is a term used to describe the typical physical appearances of a fetus or neonate due to a dramatically decreased amniotic fluid volume oligohydramnios, or absent amniotic fluid anhydramnios, secondary to renal diseases such as bilateral renal agenesis (BRA). Other causes of Potter Syndrome can be obstruction of the urinary tract, polycystic or multicystic kidney diseases, renal hypoplasia and rupture of the amniotic sac. The term Potter Syndrome was initially intended to only refer to cases of BRA, however, it has been mistakenly used by many clinicians and researchers to refer to any case that presents with oligohydramnios or anhydramnios regardless of the source of the loss of amniotic fluid.
