Bilateral
Bilateral renal agenesis is the uncommon and serious failure of both a fetus' kidneys to develop during gestation, and is one causative agent of Potter sequence. This absence of kidneys causes oligohydramnios, a deficiency of amniotic fluid in a pregnant woman, which can place extra pressure on the developing baby and cause further malformations. The condition is frequently, but not always the result of a genetic disorder, and is more common in infants born to one or more parents with a malformed or absent kidney. Males are more commonly affected and most infants that are born alive do not live beyond four hours.
