Polycystic kidney disease (PKD) is a genetic disorder characterized by the growth of numerous fluid-filled cysts in the kidneys. These cysts gradually replace normal kidney tissue, impairing kidney function and leading to complications such as high blood pressure, kidney stones, urinary tract infections, and kidney failure. PKD is one of the most common inherited kidney disorders, affecting both adults and children. There are two main types of PKD: autosomal dominant PKD (ADPKD), which is the most common form and typically manifests in adulthood, and autosomal recessive PKD (ARPKD), which is less common and usually presents in infancy or childhood.
