For the record on this G9 thread, I'm posting my recent experience with a Grade 2 urinary complication from radiation therapy. We can help one another by posting here when we have something of interest to our little community.
With 2 instances of visible blood in urine a week apart, I went to a urologist for a workup. We did urinalysis confirming microscopic blood still there (no longer visible), a CT scan to evaluate the whole urinary system, and a cystoscopy to look right up the urinary tract into the bladder. That procedure wasn't bad, but the after effects were quite uncomfortable. I stayed home from work the rest of the day.
Good news, no issues were found! Very Bad Things that it could have been weren't there. Not even visible radiation cystitis. Nothing. So, it's likely my 79.2 Gy of IGRT simply weakened some capillary somewhere that decided to seep a bit. We didn't find anything.
So, for those considering the side effect of radiation therapy, even though I did have a fairly uncommon issue it has turned out to not be significant. As always, your mileage may vary
