Hi there,
In medullary sponge kidney disease there is fluid
retention in the ducts of your kidneys. Diet
and exercise can lessen the severity of
kidney stones which may form. Organic diet may be helpful. A diet low in high protein foods like meat, low in high oxalate foods like spinach, rhubarb, peanuts, and low in sodium may help. A diet high in fiber like fruits, vegetables can be very helpful. Vitamin A is helpful in preventing the formation of stones.
