This is a somewhat gross question, but I have a kidney stone that lead to a kidney infection from the blockage. I've never seen a kidney stone before, I've been straining my urine and so far nothing stone like has been caught. I assume the kidney stone would be hard? I do have quite a bit of white stuff caught in the strainer which appears to be more of a mucus like consistency. This would definitely not be the "stone", right? Sorry if that sounds stupid, I just want to be sure. I'm really hoping I am able to catch the stone so that they can test it and determine the type and cause of it.
