My son who is 12 just had a ct scan today because he was showing blood in his urine. They were looking for kiddney stones because I have them. I am his mother. They found no stones but did find fluid in his abdomen. They want him to have inflammation marker blood tests. This worries me because I have had severe case of chroens desease for the last twelve years including two bowel resection. Could this be a sign he too has the desease or are there other causes in boys
