How to get rid of kidney stone
Drink plenty of water and other fluids. Fluid intake will make you urinate, and urination will eventually help you pass the kidney stone. Pure water is the best. Only one or two out of 10 kidney stones will require more than drinking lots of water and waiting[1], so make sure that if you do anything, you do this.
The Institute of Medicine recommends that women drink about nine cups (2.2 liters) of fluids per day. Men should drink about 13 cups (3 liters) of fluids per day.
Aim to drink enough water so that your urine is light yellow or clear. This is a sign that you are drinking enough liquids.
Drink lemonade, limeade, or cranberry juice. You should look for varieties that are low in sugar, or make your own. Lemons, limes, and cranberries are very high in citric acid, which helps prevent crystals from increasing in size and becoming new kidney stones.
Avoid dark beers. These contain oxalates, which can contribute to future kidney stones.
Avoid crash dieting. Crash dieting increases the amount of uric acid in your bloodstream, elevating your risk of kidney stones. High-protein diets, such as the Atkins diet, are particularly hard on your kidneys and should be avoided.
That said, a healthy, balanced diet with plenty of fruits and vegetables, legumes, whole grains, and limited lean proteins can be a great way to keep you healthy and prevent kidney stones.
