One effective way to dissolve kidney stones is to consume large quantities of watermelon and nothing else for an entire day. Watermelon fasts help cleanse your kidneys and the rest of your system as well. Regular consumption of watermelon helps keep kidney stones at bay.

If you can afford the ingredients, I highly recommend Herbdoc Richard Schulze's 5-day Kidney flush protocol, have done it a few times myself, works wonders, especially the gallon of brew you drink over a 2-day period, recipe on page 48. If you cannot get his ingredients, you can get close from your local health food store. If nothing else, read the book and go from there as much as possible.

There is an herbal formula called Herbal Detox by Herb Pharm. You can get it at most any health food store. My acupuncturist recommended it. About a week after I began taking it, I started seeing black sand in the toilet after I peed. I told the acupuncturist about this and he said, "Good! Those are kidney stones!" I had a bunch of tests after that and the doctor said my kidneys are very strong.
