Normally surgery (known as a TURB...transurethral resection of the bladder) is not done unless the urologist has reason to believe that there is a
problem and needs to do a biopsy.
The usual procedure after diagnosis of bladder cancer and BCG treatment is to have cystoscopy (where a small camera is used so that the urologist can see the bladder lining) which is NOT surgery, no samples are taken, and is done in the office with no anesthesia. The usual protocol is that this is done every three months for two years after diagnosis, then every six months until five years have passed, and then annually forever. If, during this exam, the urologist sees something unusual he will then move on to a TURB.
I would be surprised if your husband's urologist does not plan on cystoscopy about a month or so after the BCG series is completed. Sometimes BCG is not effective and the tumors can return. Youi might want to clarify this with the doctor.
