Kidney stone prevention
 This is some general advice to help those patients who have had kidney stones and who wish to prevent the formation of any more.
-
Drink enough fluid to maintain a urine output of 2.5 litres per day. There is some evidence that cranberry juice is beneficial and we suggest that you take some of your fluid input in this form.
-
Aim to have a diet that contains 750mg calcium each day.
-
Restrict your intake of foods and fluids that contain oxalate.
-
Avoid adding salt to your diet, although it is perfectly reasonable to use it sparingly when cooking.
-
Restrict your protein intake to one modest sized portion of red meat, fish or poultry per day.
