Hi, this is my first post as I have just joined mumsnet. Are there any other babies out there with a kidney stone? We discovered that our DS had one when he was 3 just months old. He was really poorly and ended up in hospital with a urinary tract infection, they then discovered the stone. I was so surprised as there is no family history of kidney stones. My DS is now 17 months and you wouldn't know there was a stone there. He's a wonderful little boy. Anyway, we have had regular visits to the hospital, various scans and x-rays etc. They have now said that he is old enough to go ahead and use laser treatment to "blast" the stone. It's going to be so difficult as he is too young to explain to. I'm assuming that it will be a very painful experience for him to have to pass the broken up stone. I've done so much research on the subject but there is so little information about kidney stones and infants (one recent journal article said that the occurance rate in the UK was 2 in every million per annum). Anyone other parents been through a similar thing?
