“…Originally, it was a clinical or autopsy diagnosis, 2 but successful antenatal diagnoses with B-mode ultrasound and aortography were reported in 1977. 3 Antenatal ultrasonic diagnosis of Potter's syndrome remains difficult, however, because of the poor resolution of the kidneys on such studies. Careful evaluation of the fetal bladder is very important in these cases, since ultrasonographic identification of a normal bladder is incompatible with renal agenesis.…”

Potter's syndrome, a rapidly fatal congenital disorder marked by renal agenesis, can be diagnosed in the first hours of life with real-time ultrasound. In infants with Potter's syndrome the adrenal glands assume a discoid shape and occupy the renal beds, thereby mimicking the absent kidneys. However, discoid adrenals can be distinguished from either normal or dysplastic kidneys by definitive ultrasound criteria. The ultrasound appearance of an echogenic medulla and a hypoechoic cortex in a posteriorly placed, flattened adrenal gland is quite different from the neonatal kidney with its echogenic cortex and hypoechoic renal pyramids. Early diagnosis is desirable to facilitate management of this hopeless condition. Difficulties with reliable antenatal ultrasonographic diagnosis of Potter's syndrome are discussed.

“…Aortography, however, has been suggested as the definitive diagnostic procedure, particularly in those patients in whom there is confusion over the ultrasound findings. 17 The three reported in utero cases are of interest in that they represent a wide spectrum of adrenal abnormality in bilateral renal agenesis. In case 1, the diagnosis of renal agenesis was not in doubt since the kidneys could not be demonstrated.…”

Three cases of renal agenesis are presented, representing the spectrum of abnormality seen in utero. Severe oligohydramnios was seen in all three cases. In two cases ultrasound demonstrated fetal paraspinal structures resembling kidneys, while in the third no renal shapes were identified. The urinary bladder could not be imaged in any of the cases. Autopsy findings demonstrated that the reniform structures represented only fetal adrenal glands of varying sizes. It is suggested that the examination of the renal tract in severe oligohydramnios should be directed toward the fetal urinary bladder, because the identification of reniform outlines can be misleading.
