And the stone was...

Just over 4mm at its widest part. It wasn't set right on that tape measure, but I couldn't tell until the pic was blown up.

Passing it didn't hurt at all. I didn't feel anything, and thankfully, it didn't hurt my ureter on the way down either. A year ago or so, I made a joke about my ureter being a slut. Now y'all get it? It's either dilated (*cough* "loose" from stones and cystoscopes) or scarred all the way on down. I'll take either. I mean, I forget how many times I've been told that stones 4mm and larger don't usually pass, let alone without pain. Maybe I should come up with a kinder analogy. A proverbial high-five of sorts, instead of an insult. ;)
