I'll bet that you are happy to have this one behind you!!
You may have had a wash with mitomycin after the biopsy...or maybe not if there were a lot of "wounds" from the burning off of the other "spots." A catheter is not necessarily an indication.
Of course, a lot of your questions will depend on the path report. If it is high grade, does he recommend BCG or some other treatment?
As for a second opinion, that is always a good idea IF YOU KNOW WHAT QUESTIONS THE SECOND OPINION IS SUPPOSED TO ANSWER. If after you digest the results of the TURB/pathology, you have some concerns and questions about the treatment that your urologist is recommending, you absolutely want to have a second opinion. If you are very comfortable with his plans (and you have checked out his reputation...which it appears you have) it may not be necessary. A second opinion just to get a second opinion is not necessarily efficient or helpful. As they say, "It Depends."
For example, I had checked out my urologist's reputation and training background. He trained with the best. He has been very open to my questions and we have had many discussions. When the 2nd TURB results were back (and the 2nd TURB was also an indicator that he knew what he was doing) and he insisted I cancel a long-planned trip to China to start BCG, I checked out the path report and his recommendations with a friend who is an Army urologist. She confirmed that everything he said and did was "right on." He also told me that if the time came to recommend a cystectomy he would INSIST that I get a second opinion. So I have not felt the need for going after one.
In another, totally unrelated condition, I had an orthopedic surgeon who I felt was "surgery happy" and was rushing me to surgery. The whole deal just did NOT feel right to me. I pulled out, got a second opinion which recommended trying some more conservative options first. Three years later, problem solved, no surgery.
I guess the reason I am telling you this long story is to say that IF you feel totally comfortable with your doctor and IF his plans conform to what seems to be the standard of practice, you are fine. IF at any time you feel uncomfortable or uneasy or unsure SECOND OPINION TIME!!
