What is Kidney Dysplasia?

Kidney dysplasia is a congenital (present at birth) condition where one or both kidneys do not develop properly in the womb. Instead of forming healthy, functioning kidney tissue, parts of the kidney are replaced by fluid-filled sacs called cysts. These malformed kidneys cannot filter blood or produce urine properly, which are essential functions for a healthy body.

Kidney dysplasia can affect one kidney (unilateral) or both kidneys (bilateral):

Unilateral kidney dysplasia is more common and often doesn’t cause symptoms, especially if the other kidney is healthy.

Bilateral kidney dysplasia is more serious and often fatal, as both kidneys fail to function properly.

How Common is Kidney Dysplasia?

Kidney dysplasia is more common than many people think. According to medical research, it affects about 1 in every 4,000 births, with boys being slightly more likely to be affected than girls. Most cases involve only one kidney, which allows individuals to live healthy lives with minimal complications.
