When there is ANY doubt a second opinion is always good. I don't remember if in prior threads if you said it was muscle invasive, high grade or questions or margins being sufficient which usually triggers a second TURB. IF, a second TURB shows stage 2 or worse (muscle invasive), then a cystectomy gives a better chance of beating this. I am linking a site on diversions (our hyperlink doesn't seem to work so copy and paste) if needed, see:
my.clevelandclinic.org/health/treatments/12546-urinary-reconstruction--diversion. You want a surgeon that does 25-35+ a year as this is a complex surgery. Also I am adding a questionnaire to ask doctors so pick and choose which ones pertain to you on treatment plans. Keep posting away with questions.
