Yes, second BCG treatment was Tuesday (2 days ago). The 2 hour (1 hour, 55 minutes actually) dwell time was without consequence. I set my phone alarm every 15 minutes, rotating like a rotisserie hot dog at the sound of each alarm. I had no urgency whatsoever until I arose, at the 1:52 mark, to prepare for the first void (went to fetch bleach and a huge glass of water), and immediately felt an overwhelming need to urinate. Lesson learned: stay down UNTIL the full 2 hours has passed, if possible. The first void was painless and I assumed this 2nd treatment would be as problem free as the first. Lulled into a false sense of security, I drank my second 16 ounce glass of water, donned my winter gear and headed outside to start my snowblower so as to tackle 12" of snow that fell after a recent storm.
That was a mistake. About 15 minutes later (2 hours and 15 minutes after the instillation) the urge came on fast and strong. I was I full winter gear (temperature was around 20 degrees F) and operating a snow blower with a bladder full of diluted BCG. Run Forrest, run.
Throughout the next 7 hours I drank copious amounts of water and experienced excruciating pain and gross hematuria (observable blood in urine) while urinating. The pain felt like it originated along the urethra and not within the bladder and the pain (razor like) and bleeding ONLY happened toward the end of the urine stream. What's up with that, anyone? Damage done by catheter during instillation, perhaps?
At some point (about 6 1/2 hours after first void) I grew tired of water so I made a cup of tea (Traditional Medicinals Nighty Night) with fermented honey to sweeten (my gal keeps bees). Almost immediately thereafter the bleeding stopped entirely and the pain began to subside. The next morning I awoke feeling a bit run down but within 24 hours after the instillation began I felt entirely myself again.
I'm admittedly a "numbers guy," professionally and personally. With respect to your recent TURBT, I believe the odds are in your favor that the pathology report will once again show low grade, non invasive. While I can understand your anxiousness, especially in light of my experience (low grade > high grade), this process is teaching me that it is best to not become overly concerned about things until I have good reason to.
I hoping the best of all outcomes for you.
