I only had 3galblader attacks in 2weeks 2months ago. i was checked, have small stones andnow i'm going to surgically remove bladder. is that necessary?

Personal decision: Yes you can have laparoscopic surgery to remove your gallbladder ; gallstones if you want. Unless there are medical reasons that requires you to ihave surgery, such as abnormal blood liver tests or history of gallstone pancreatitis, it is your decision with your surgeon to make that decision. You are young ; have already had 3 painful attacks ; you do have risks of future gallstone attacks as well.
