re: Is there no way to take gall stones out of the gallbladder?

The stones are not like kidney stones. Majority of kidney stones are calcium oxilate, which means they hold their form when grasped and respond to breaking up by ultrasound.

Gallbladder stones are like wet sand, they fall apart when grabbing them, meaning we can’t open up the GB and just pull them out. The GB also doesn’t respond well to being opened and closed with sutures, leading to bile leakage. Lastly, the stones don’t absorb the same ultrasonic waves that would break them up. And even if they do, what’s left is wet sand that will reform. That wet sand will go down through the ducts and block them, just like a full stone.
