they wound give you a funnel thingy to urinate in with a screen in the bottom so you could catch the stone so they could analyze it.

I passed one in 1984 and it was the size of a #5 shot with little stickers all over it. Took about 4 hours of excruciating pain to pass into the bladder. The next day out it came. Passing it out from the bladder to the filter thingy was the easy part.
