Jerry,
Welcome. You are checking all the boxes to get rid of this. The second opinion at Emory was a good move and from what I understand is an excellent center for this disease. Having a 5th BCG treatment is good with what I assume will follow with one more before a cystoscope to look. I doubt they will do another TURB unless things don't look right.
Keep posting as you have more questions. With some kind of maintenance in BCG, the odds are with you that will be the end of this. As we all say, keep those appointments and follow-ups!
