Of course my doctor said there is no other way but I refuse to go into surgery, especially when I never had any pain or symptoms of gallstones, they just showed up on my ultrasound.

There's a herbal tincture called Chionanthus Virginica that dissolves gallstones.
The TCM cure is to expel them using a mix of olive oil, lemon juice and epsom salts taken before bedtime. You can find the protocol online if you look for it.
Most people have gallstones and don't even know it. if you're asymptomatic no problem. Unnecessary gallbladder surgeries are epidemic (so are routine hysterectomies).

Lithotripsy uses ultrasonic shock waves to break gallstones into small pieces which can be safely passed, but this method is not suitable for all cases. Cholesterol gallstones can sometimes be dissolved by oral ursodeoxycholic acid but it can take years to work.

If they are not causing you any grief you probably don't need to worry about it, but gallstones can lead to blockages which can be nasty – perhaps your doctor is worried about that.

Olive oil, lemon juice and epsom salts don't work – what comes out looks like gallstones but actually they are bile-stained "soaps" produced by partial saponification of the oil.

Chionanthus Virginica has been used for gallbladder inflammation, I doubt it will have any effect on gallstones. perhaps @thenoseknows would care to post some substantiating evidence for that claim.

might not work and there are some risks
surgery is usually the best way. you dont really need a gallbladder anyways
