Welcome to Healing Well.
The only experience I have with this is my mother had something similar. She had colon cancer and it had spread to her ureter. They removed the cancer and she is doing very well.
Not trying to say this is what you have going on, but it's the only time I have heard of it.
Myself I have small ureters and can't pass any stone 4 mm or larger and don't handle stents well at all.
