Actually, finding the right piece of wire was the challenge.

It needed to be rigid, but narrow.

Most paperclips would have worked on a shorter bit of urethera,
but I had to settle for something a little thicker than I would have preferred in order to get deep enough in there.

Once it was dislodged from the inflamed tissue immediately surrounding it, I probably could have just squeezed it out,
but I wanted to get it over with, since I now had a loop jammed in there in such a way that the stone probably needed to come out first.

The last thing I needed was a kidney stone and a mangled paperclip squirting with a liter of bloody urine out into my pants while I was
on the job massaging the feet of someone listening to new age music.
