My once-per-week for 6 wks BCG treatment is in one week, 13 days after my TUR. My urologist does in his office. After BCG is put in my bladder & catheter is removed, I leave the office & then wait 2hrs before expelling. I have an active bladder. Aside from the usual requirements of discontinuing fluids 6hrs before treatment, deferring taking of diuretics until after the treatment, etc., does anyone have any other advice to ensure I retain the BCG for 2hrs? Thank you.
