Osmosis video - Multicystic dysplastic kidney

Multicystic dysplastic kidney (MCDK) is a congenital disorder in which the kidneys fail to develop normally and cannot drain urine properly. This causes urine to build up in the kidneys and forms multiple cysts.

MCDK is often detected during routine prenatal ultrasounds, or during early childhood with hydronephrosis and recurrent urinary tract infections of the affected kidneys.
