Thanks again everyone. Underwent the surgery on Wednesday evening, the stone was removed cystoscopically under general anesthesia, then a stent was placed in the ureter between the left kidney and bladder. A length of suture material was attached to the end of the stent, which is now dangling out the end of the urethra. Still in a bit of pain, peeing blood, but with luck, things will improve on Wednesday when the stent is removed. I'll keep you posted.
