The complete absence of one (unilateral) or both (bilateral) kidneys. Agenesis means "without a beginning".
Also known as Potter's Syndrome, bilateral renal agenesis is the complete absence of both kidneys. Severe oligohydramnios (too little amniotic fluid) results, causing growth retardation, typical 'Potter's facies' (beak-like nose, receding chin, and large, low-set ears), and pulmonary hypoplasia (failure of the lungs to reach full size). This condition is incompatible with life.
Personal experiences with either form of the disorder, including memorial pages. Various forms of this disorder go by the name of Potter's Syndrome, Potter's Sequence, Renal Agenesis, Bilaterial Renal Agenesis.
