Laser Ultrasound

Someone I know has a 15mm gall bladder stone. They only came to know abt it last week when they had a moderate gall bladder attack. Ultrasound showed the stone. Surgery has been advised. The doc said that it’s ok if you put off having surgery for like a month or two, but don’t put it off indefinitely. If you have important work and want to delay it, just make sure you don’t eat any fat in between (as it cud prompt another attack).

I want to know if some other non-surgical technique is there which really works, which is safe and effective in dissolving the gallstone, which cud be attempted in this 1-2 months time frame that they have got? And my second question is that can Lithotripsy (spelling?), which is used to shatter kidney stones) be used to shatter the gall stone as well, and will it have any negative side effect?
The reason for looking for a non-surgical technique is because the doctor said that, in gall bladder surgery, the whole gall bladder is removed along with the stone. And since they want to avoid removing the gall bladder (unless of course there’s NO other option), they want to know about alternatives.
