I'm back from the hospital already. They stuck 3 probes through my back into my kidney that looked like bent coat hangars, and one with a tiny snipper on the end to get a sample for biopsy. They said they sedated me, but i was awake the whole time asking questions. They slid me in and out of the CT scanner a bunch of times to see what they were doing on a TV screen. They seemed to know what they were doing. So young they probably trained on video games. "Take it easy for a couple of days," they said, and "Go to the ER if you're peeing blood or passing clots, or can't pee at all." I didn't ask about sledding or ice skating.
