Paula, yes almost positive the fistula would make you not a good candidate for mitomycin. However, knowing nothing about either doc you are seeing, choose whoever you think is most competent at removal. The removal and getting the margins clean is important. A good question to ask, as we learned, is how mant TURBTS do you do a year? Our first uro did 30. Our oncologist/uro does well over 200. Keep us posted. Wealth of info from folks here.
