Bilateral Renal Agenesis is the absence of both kidneys at birth. It is a genetic disorder characterized by a failure of the kidneys to develop in a fetus. This absence of kidneys causes a deficiency of amniotic fluid (Oligohydramnios) in a pregnant woman. Normally, the amniotic fluid acts as a cushion for the developing fetus. When there is an insufficient amount of this fluid, compression of the fetus may occur resulting in further malformations of the baby.
This disorder is more common in infants born of a parent who has a kidney malformation, particularly the absence of one kidney (unilateral renal agenesis). Studies have proven that unilateral renal agenesis and bilateral renal agenesis are genetically related.
