Ya, some pieces pulled through the urethra, but the biggest chunks through my back. They tried but couldn't penetrate the lower kidney below my ribs, so they had to get it done a few days later between my ribs. Horrible ordeal. You are the only guy I ever knew who had that done too. It's long time ago, but I still remember the name of the procedure - percutaneous nephrolithotomy.
They left a nephrostomy tube in my back for several days to drain it. I started throwing pulmonary embolisms in hospital so they cranked up my bed to do an xray and that pulled on the tube that was anchored in my kidney. I screamed like a banshee and terrified everyone in the entire hospital. It was amazing how many people were cured and went home that day.
I was never eligible for lithotripsy despite practically begging for it. So I have no idea what that is like.
When I say that I feel your pain, I really mean it.
Just think, we both lived to talk about it! Prolly should stop here though. Too many nasty stories to tell that nobody wants to hear.
