Kidney Stones 9-12 inches both kidneys

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.

My stones are the opposite of yours and 90% calcium oxalate ... I limit my calcium and oxalate intake and my Uro suggested Magnesium or Urocit-K but that may be because they are calcium based....not sure ... but worth asking your specialist about.  I could not take the URocit K due to awful side effects but it really does help many people from what I've heard if you don't get the GI upset from it.  It's a prescription.

My gallbladder has documented stones but quiet now for 2 yrs .. shhhhhhhhh

My 17yr old had her diseased, dysfunctional GB out last year and lost 50lbs in the process and is so healthy now!!!!
