Andrea,
No, I don't think it will do the job; I wish it did. It can certainly cause diarrhea, as Epssom salts could, but that doesn't mean you will get out trapped stones.
Actually, colon flushes existed in Ayurveda for at least 6,000 years. Jesus and the Essenses also taught how to do enemas, using skin bags to hold the water and inserting hollow plant stems for the tubing. The Ancient Egyptians and Romans also had similar devices.
