Thanks, it's remarkable how much better I feel without that damn thing inside me.
And yes, the offending object was captured and will be turned into the doc today for further study (if necessary). Despite the lithotripsy the stone appears to have come out nearly whole. I took some quick measurements (turn away if you're squeemish) and it's a little over 1/4" (~6.5mm) long and at it's widest about 5/32" (4mm) in diameter. Not small.
Lesson - I will be drinking a lot more water for the foreseeable future.
