You must get them out!
Without getting stones out, you will never know what came out from your liver/gallbladder.
Use colander.
What if you flush out a calcified stone, and you flush it down? You would never know.
What if you pass a worm, something that nobody have ever seen before, undiscovered parasite, and you flush it down, without ever knowing what kind of
parasites you might have inside of you?
What, if after several flushes you want to know if your stones are changing from flush to flush? You will never know.
When you flush down your stones, you are flushing important information, information that you would never again be able to collect.
What is the point in flushing liver, if you have no basic knowledge about what you are doing and what is coming out of you?
