A friend of mine had some large kidney stones dealt with about 2 years ago. They were som bad that when he went for a pee....he could produce nothing much more than a puff of dust.
A specialist from USA was out here on business and was alerted to his case somehow.....long story short he was rushed up the queue and treated quickly. After a week or so from the op he had to pull the strings out of his kidneys via the 'ole fella'......I believe his wife helped with this in a very warm shower. He did tell us at the time how relieved he was after a day or so from removal.
Now he can piss like a cart horse again. (Not a Budweiser one though ...they sit down to piss.) :lol:
BTW....this friend is the guy who mastered my disc brake swap.....and we did that only weeks before his op. He was in a lot of pain rolling around on the floor under my truck at the time. We took it slowly, and I ended up doing more than I thought I would myself.
