Welcome sixftseven,
For sure BCG is the most used agent in this country. I am hearing the shortage is slowing down but, others may have more accurate info. Gemcitabine along with mitomycin along with other chemo washes have also been used effectively. The stats I have seen....and I never totally trust any study because of conflicts etc that BCG and the other treatments are pretty close in effectiveness. Plus, some people will react to each agent differently, so who knows.
Usually after the TURB most people/docs will wait 6-8 weeks for healing so you may have a little time to do further research and also locate someone with BCG. I have to admit I like the idea of immunotherapy vs the chemo wash but, if either works who cares. I am bookmarking just one study that discusses what we have already opined on. Just copy and paste:

In the body of that study is "Some people who are at intermediate risk of recurrence will be advised to have either a full six-week course of intravesical chemotherapy, most commonly mitomycin or epirubicin (see 'Intravesical chemotherapy' below), or intravesical immunotherapy with Bacillus Calmette-Guerin (BCG) (see 'Intravesical BCG' below). Both kinds of therapy usually involve additional booster treatments for up to one year (maintenance therapy).
