Yeah, that's big.: A stone up to 5mm in size will predictably pass, with variable degrees of pain. A 12mm stone is going to get stuck if it decides to move out of the kidney. You should get that stone managed before it starts to move.

Maybe.: There are many ways to deal with stones. It depends on their composition, size and location. Usually a stone that size will require some sort of intervention, and may be amenable to eswl (extracorporeal shock wave lithotripsy).

Lithotripsy may break up the stone so that the smaller fragments can pass through the urine.

Lithotripsy: They either shock it into crumbles with a process known as lithotripsy or they go in and get it surgically.
