Hey Henry. I had a stricture develop after one of my TURBTs. Doc used tools of increasing size to stretch it and allow better flow. I haven't tried anything like you're describing. However for BCG instillation, I'm pretty sure they will use a much smaller catheter. I think they used a 15 French size when I had a couple of rounds with BCG. The Foleys are much larger. I've had those and they've been either 22 or 24 French. Stu
