Hi Darryl
Getting a 2nd opinion at a major cancer centre, with a top Urologist who specializes with bladder cancer is very important in your case. If he/she agrees with your current Urologist it will put your mind at ease. Their are a couple of schools of thought when dealing with a CIS recurrence that is still non-muscle invasive.
Some have had success with BCG/Interferon treatments as interferon has had success in boosting the BCG. Others have chosen to have their bladder removed at a major cancer centre.
If you are incurring delays in seeing a top Urologist at a major cancer centre, I may be able to assist in speeding up the appointment.
Hopefully others who have experienced what you are, will chime in and share their decision making process.
All the best,
Jack
