I am 42 years old and have Crohn's disease, diagnosed in 1998, and am wondering if the kidney stones I am having, could be a result of of something more serious going on. I have had a 9mm kidney stone removed with a basket extraction, in April 2008, from my left ureteral and a 10-12mm stone crushed, in May 2008. My x-rays, a year ago, showed that I have multiple renal calculi. I have been under a urologist care for a year. He did tests to see what kind of stones I had and the lab results showed that they were 90% hydroxy-and/or carbonate apatite and 10% calcium oxalate monohydrate. He said this was not the stone that he was expecting. He did a 24hr urine and blood test and tested calcium, oxalates, uric acid, citric acid, phospherous, Bun, and creatinine. He said that all of the results were in normal range.
I asked him if there was anything I could do to prevent more stones and he said just increase my fluid intake. I am starting to have problems again with my kidneys and was wondering if I may need to see a specialist this time for more test or is this something I will have to live with.
I also had to have my gallbladder removed in May of 2009 because it was diseased but it had no stones.
