text: I'm sure no doctor but know that you have to feed your kidneys to keep them functioning properly.  Drink lots of water.  You can also drink cranberry juice but not too much if your on a diet or are diabetic cause its loaded with sugar.  Still 4 to 8 oz. a day won't hurt you.  Read up on natural antigens and antioxidants.  There are lots out there and they can help.
