MB,
I was instructed that there could be heavy bleeding about 2 to 3 weeks after each TURBT, there could be many clots, and that if it happened, to call the office. The timing was not fixed, but related to scabs coming off the biopsy areas.
Happened to me on turbt 5 or 6, overnight, and shortly after I was blocked. My uro is 3 hours away, so I was sent to my local emergency clinic, where they pumped the bladder clear of clots. As you describe, this was HEAVY bleeding, not just red urine; I clogged within a hour of the first heavy blood. Next time I won't be waiting an hour to see what happens, or to make sure I understand what the doc means by heavy bleeding..
Glad you seem to have cleared up.
Best
Jack
