What is it?

Medullary sponge kidney (MSK) is a rare congenital disorder characterized by small cysts forming in the renal tubules or the collecting ducts, in one or both kidneys. These fluid sacs reduce the outflow of urine from the kidney. It is more common in women, and the reason for the disorder is not yet known. The condition leads to kidney failure in about 10% of the patients.
