My Lab Tests are back

Hai,
I did two flushes and i did collect some stones in my first flush to show to my PCP.She did send them to the lab for tests.My test results came today .The results showed that the stones does not contain any cholestrol or bile stones and they are not gallstones.She advised me that, if I have any attack go head and get the operation done before it is life threatning.The stones i passed were of the size of a peanut and they are green in color and shiny.I really don't know what to do?
