How to fight kidney stone?

Water: There are many foods to avoid or cut back. I would suggest googling those. Really the most important thing is hydration with plenty of water. Rarely, you may need medications, but this shoule be under the guidance of a urologist.

A metabolic work-up : The best way to fight stones is to understand your metabolism. I believe that most stone formres should have a metabolic work-up. This should include blood levels of calcium, 24 hour urinalysis (looking at calcium, citrate, oxalate, etc). Good intake of water avoiding certain foods (high in calcium, oxalate) and medications (citarte, diuretics) may be necessary to fight stones.
