Hi, off topic but-- my father had these, several a year for two decades. Some mornings we would wake to a note on the counter that said something like "Kidney stone, at the hospital."

That being said-- the trick for him turned out to be stopping soda, and keeping a water bottle by his bed and drinking a gulp of water everytime he woke up-- basically staying hydrated during the evening, and at all other times.

Just wanted to mention this in case it was of any use. Also, keep an eye on RCC. :-/
