Year ago this past Labor Day weekend (Fri. nite naturally) had the same thing, same size. Got some morphine at ER and hydra contin script to hold me. ER set me up with a urologist for Tues. AM. Had another X-ray that morning, stone was still there, and then got the sonic procedure. Was home by 3 PM.
Procedure worked well, only very small pieces of debris in trap. Lab said it was oxalates.
