[Ultrasonic diagnosis and prognosis of fetal multicystic kidney dysplasia].

Objective: To explore the diagnosis, clinical course and prognosis of fetal multicystic kidney dysplasia (MCDK).

Methods: 24 858 pregnant women detected by prenatal ultrasound, here were 41 cases with fetal multicystic kidney dysplasia, these fetuses were diagnosed at average 29.8 weeks of gestation, Carried on an observation to fetuses with multicystic kidney dysplasia and postnatal follow-up study.

Results: T17 cases were induced abortion. Of 13 infants, 1 case involute, 3 cases decrease, 9 cases no change.

Conclusion: Prenatal ultrasonography can actual diagnosis for fetal multicystic kidney dysplasia, the key of management of multicystic kidney dysplasia is assessment of fetal prognosis, the natural history of unilateral MCDK is usually benign, the affected kidneys tend to show involution after birth. But bilateral MCDK often associated with impairement of renal function, abnormal chromosome or other anomalies, which indicates a poor prognosis.
