Does anyone know:
(1) which treatments for prostate cancer are dependent on the man having a fast enough flow rate? (before prostate treatment).
(2) what rate of flow is usually deemed sufficient? Is it 10 ml of urine per second for 20 seconds, or what?
Reason I ask: I've been told that I may possibly be allowed to choose HIFU focal therapy but I have to pass a flow test first. There's no indication of what the "pass mark" is.
When I asked ( during one of those formal NHS phone calls) the risk of retention was mentioned. I'm guessing they think that HIFU, even though aimed at just one peripheral lobe where my cancer is (localised gleason 4+3, no mets), could cause my overall prostate to expand and potentially compress the urethra.
I'm told that my pre-decision flow test will include imaging my bladder full, and again when I've emptied it. This is to check any pre existing failure to properly empty. But again does anyone know, just how much retained urine would be deemed a problem, for deciding which cancer treatment to give me?
Background: the hospital previously indicated they'd be happy to give me radiotherapy if I choose it (EBRT + HT I think they mean) even though RT swells prostates permanently, according to other threads here.
