Medullary Sponge Kidney(MSK)is an adult disease, which is characterized by dilation(swelling)of collecting ducts in the kidneys. The collecting ducts are the part of the kidney, where the filtered urine will eventually pass through before being excreted into the pelvis of the kidney and out to the bladder. There could be numerous cysts(contained pouch of fluid)associated with these ducts. A significant number of the patients with MSK are asymptomatic, and their condition is never diagnosed. The most common symptom associated with MSK is renal (kidney) colic(50 to 60 %)followed by urinary tract infection(20 to 33 %)and bloody urine(10 to 18 %). About 1/3 to 1/2 of patients with MSK have high blood calcium. Less than 10% of asymptomatic patients may have a poor long term outcome due to kidney stones, kidney infections, and kidney failure. However, with the appropriate treatment for increased calcium and kidney stones, as well as prevention of infections and kidney failure, this number is reduced. You need to have close follow up with your doctors if you have any of the conditions described.
