Thanks for the all the info.Alyssa - I saw that you mentioned mis-diagnosises. When I first took him into the ER they ran numerous tests and x-rays and finally admitted him because they said he was constipated. Now just a month before we had been told he was upset and crying because he was constipated and it ended up he had a broken leg!!!, so I was not happy with their answer. I told every single doctor, nurse and child life lady that walked into my son's room that poop was not causing this amount of pain. Everyone tried to assure me that it really could be painful to be constipated. Finally I had had it with them pumping him full or Miralax and giving him enemas all the while with him screaming, so I insisted they do an x-ray to totally rule out the "constipation" diagnosis and move on to finding out what was really wrong with him. That's when they saw the kidney stones. I have no idea why they didn't see them on the previous x-ray that made them think he was constipated.Two of those stones were 3 mm and one was 2 mm and they said they don't try to break them up unless they are 5 mm or larger and they just were going to wait until they passed on their own. An actual stone never really passed though, but there was a white-ish looking sediment at one point. I had asked the nurse if that could be the stones and she said no and just cleaned up the sediment. Then later that night I asked the doctor about the sediment and he was upset the nurse didn't keep a sample of it for testing. So it was never tested. They did test his urine though and said it was high in calcium so they thought it was probably a calcium stone.The doctor in the hospital did mention the Citrate, but my son has low bone density (hence the broken leg the month before) and the Citrate can cause low bone density, so not sure if they are going to put him on that or not. We see a Nephrologist on December 19th so hopefully he will have answers for us and a game plan to stop the stones from happening. Because if I have to pick kidney stones or broken bones I don't know which one I would pick<img src="i/expressions/face-icon-small-confused.gif" border="0">.
