I've had the first 6 week course and my first maintenance of 3 weeks with a scoping between, AFTER a similar round with another doctor and again 5 years earlier. The scarcity of BCG was interrupted that plan. All treatments were uncomfortable, some with a little blood clotting. Three things I've found helpful. If you are a man, insist on them using a catheter that has a curve in the tubing at a critical point that passes by the prostate more comfortably. Second, find a doctor who has enough treatment rooms so you can stay there for the 2 hour waiting time holding the BCG while they leave in the catheter, and then use it to drain your bladder including the BCG. Diminishes the difficulty of driving home while holding in the BCG, and draining out most of the BCG via catheter is much less uncomfortable than peeing it out. Third, I found that an ice pack on the groin will reduce the pain of inflammation both while holding in the BCG and later at home while still getting some irritation from passing what remaining BCG is in your bladder. And a fourth bonus, find a doc (or nurse) who GENTLY inserts the catheter. My first doc would pretty much ram in the catheter past the prostate while the current nurse is far more gentle. Irritating the prostate makes for more pain urinating later.
