Bilateral multicystic dysplastic kidneys -- an unusual case diagnosed on antenatal ultrasound.

While it is true that unilateral multicystic dysplastic kidney is commonly associated with abnormalities in the contralateral kidney, it is not widely known that the condition may be bilateral. The recognition of the bilaterality of the multicystic dysplastic kidney by ultrasound has grave prognostic implications as this condition is uniformly fatal. High resolution ultrasound examination of the foetus enables early detection of congenital malformations of the urinary tract. This information is of value in determining foetalprognosis, in deciding the method of delivery, and in alerting the paediatricians to supportive and corrective measures which may need to be taken in postnatal period.
