My Dr. thought I had a stone so he put a stint in, moved it four days later. I had a lot of trouble with burning and pain in the right side, ordered a x ray with dye, showed the kidney was very enlarged, he said that it was his fault , because of removing the stint. Cant find out what is wrong but still having proublems with burning when I pee. But it comes and goes every few days. I can take one dose of Azo and it will go away for a few days then return.
