Hi I have had multiple stones since 2006 and have always to have them removed surgically. I have a large stone 1.1cms in the right upper pole of my kidney in a calyx. Unfortunately tried percutaneous stone removal my surgeon said it was just out of reach. Subsequently I experience rapid onset of pain due to I believe are biofilms which cases rigors and pain. My Urologist does not accept that I am in pain as his opinion is you only get pain when the stone is migrating. I beg to differ please help
