I have had 2 TURBTs - the first, I did not have mitomycin (although I was told that would be part of the procedure). the second (blue light) I did have mitomycin post surgery. First one was papillary (95% LG - 5% HG) the second was CIS (always HG). Not sure why or why not. As far as standard protocol - I will defer to someone with more knowledge.
