Antenatal diagnosis of renal anomalies with ultrasound. IV. Bilateral multicystic kidney disease

Abstract

Bilateral multicystic kidney disease is a congenital disorder that is fatal in the newborn period. A series of nine cases of bilateral multicystic kidney disease diagnosed prenatally by ultrasound is presented. Ultrasound criteria necessary for the diagnosis are bilateral multicystic kidneys, loss of renal architecture, nonvisualization of the fetal bladder, and absence of amniotic fluid. Seven of the nine cases had autopsy confirmation of the diagnosis. Three cases had other associated congenital anomalies. Precise prenatal diagnosis may allow patients the option of elective abortion or may prevent unnecessary obstetric intervention. We propose that a reliable diagnosis can be made with prenatal ultrasound.
