I have no idea what kind my stone was. I think my surgeon was ready to be rid of me due to the scheduling error on his part being a little embarrassing. None of the doctors recommended any changes or gave me a suspected cause for my stone, so I wonder if that's because it was one type of stone or another. My suspicion is that my stone was brought about by some very rapid weight loss on my part along with poor hydration.

The research page that mentions the study doesn't say whether they're looking at specific types of stones or just all stones in general.

Edit: I recalled that my kidney stone was never visible on fluoroscope/x-ray and so it was most likely a uric acid stone.
