Yes: And too big to pass on its own.
Dr. Dean Giannone
Internal Medicine 26 years experience
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.
