Is there any other way to treat gallstones?

I read upon other types of treatments such as therapy. Is there any medicine for gallstones yet? Mines isn't inflammed. I was referred to the gallbladder doctor and I been having pains. I showed the doctor my ultrasound that my primary physician ordered and he thinks my gallbladder shouldn't be removed because of the gallstones isn't inflammed. I was naming every symptom I had and currently still experiencing right before I found out i have gallstones. now this Friday he wants to do a colonoscopy to see do I really have gallstones or is it my colon instead. I'm so confused. I don't want to be operated on if there's other treatment but gallstones can be deadly
