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).
HOW IS RENAL AGENESIS DIAGNOSED?
Renal agenesis is typically diagnosed during routine prenatal ultrasounds. When BRA is identified, prenatal MRI can be used to confirm the complete absence of both kidneys.
HOW IS RENAL AGENESIS TREATED?
The absence of both kidneys is fatal and babies would die within the first few days. When a single kidney is present the functioning of this kidney and whether or not other complications are present would determine treatment options. Annual blood, urine and pressure tests would be advised to ensure no further complications develop.

The mortality rate with such infants is very high. Very few survive and those who do continue to have various kinds of physical problems.
