Might get something caught in the Common Bile Duct.
The ultraphos relaxes the Common Bile Duct, makes it pliable.
I've seen other flushes where stones did indeed get caught and it's not nice. Very painful. It is literally a gall bladder attack.
Obviously it's not mandatory. I've done "emergency" flushed without the AJ or ultraphos but I don't advise it.
My wife had a gall bladder attack before she ever did a flush and I can assure you you don't want to have one.
So you may get away with it but again please don't do a flush without the ultraphos. In an emergency - fine. But you're playing with fire without it.
