Medullary Sponge Kidney (also known as Cacchi–Ricci disease) is a congenital disorder of the kidneys characterized by cystic dilatation of the collecting tubules in one or both kidneys. Individuals with medullary sponge kidney are at increased risk for kidney stones and urinary tract infection. Patients with MSK typically pass twice as many stones per year as do other stone formers without MSK.
