A Bilateral renal agenesis
Bilateral renal agenesis occurs in approximately 0.3 of 1000 births. This malformation is incompatible with life, with the infant living in utero, due to placental support. Oligohydramnios is seen since there is no excretion of urine during pregnancy. Early metanephric diverticulum degeneration, or failure to form, results in the agenesis.
