From what I have read, there have not been reports of Remicade causing kidney stones.
Kidney stones ARE known as an extra-intestinal manifestation of Crohn's disease. Basically people with CD are prone to getting kidney stones. I had a long and painful bout with kidney stones early on in my disease. This was years before I took Remicade.
Kidney stones that are too large to enter the ureter can cause pain in the flank area of the back. Those stones now are often broken up using sound waves. If a kidney stone is small enough and happens to get into to ureter, it can cause intense pain and blood in the urine. That's what happened to me. The stones got in the ureter and got stuck. I recall falling to the floor in the worse pain of my life, clutching my back and projectile vomiting. The pain was far worse than giving birth naturally.
I would consult with a urologist to find out what he/she plans to do about your stone. I hope that the doc can find a way to relieve your pain.
