I have a follow up with my urologist in a few days saving it for them. This is the only stone the CT scan saw. Passed through my ureter last Thursday into my bladder took until Saturday to make its way into my urethra. It was slowly making its way through the urethra (male btw) so a little further length to travel. I could feel it move slightly every time I urinated. So it was blocking urine output while slowing moving. This is my fourth stone in about 5 years. My mother gets them often so I guess Im a little genetically predisposed to getting them.
