Polycystic kidney disease (PKD): <br />An inherited disorder characterized by many grape-like clusters of fluid-filled cysts that make both kidneys larger over time. These cysts take over and destroy working kidney tissue. PKD may cause chronic renal failure and end-stage renal disease. <br /><br />THE PKD FOUNDATION is the only organization, worldwide, dedicated to fighting polycystic kidney disease. <br /><br />The mission of the PKD Foundation is to: "Promote programs of research, advocacy, education, support and awareness in order to discover treatments and a cure for Polycystic Kidney Disease and improve the lives of all it affects." <br /><br />Polycystic Kidney Disease (PKD) affects 600,000 Americans and 12.5 million children and adults, worldwide: 22,928 in Ohio alone. There is no treatment or cure, but there is hope.
