My husband had complications after a radical cystectomy and neobladder formation for aggressive bladder cancer. His one kidney was damaged by a blocked ureter from the surgery and we saw different ureter specialists at Mayo Clinic Rochester where all his surgeries were performed. Dr. Boyd Viers was able to reattach the open ureter to the neobladder. I can imagine that location of the tumor makes a difference as to the option of surgery to remove tumor and repair ureter. Perhaps you can get your information to a referral center ureter specialist for a second opinion? In the long run, it is better to be living with one functional kidney and no cancer if you can be cancer free. Good luck.
