Jeff, I'm sure there's something I'm missing here, but it seems to me that the bleeding has to be coming from the bladder south. I would think that any appreciable vacuum applied to this region would only serve to collapse the ureter. Hold it....Could the vacuum be partially collapsing the bladder, and placing torsion on the ureter?
I'm trying to put my fluid hydraulics engineer cap back on for a bit....said cap is a little moldy from non use.
Since you only have bleeding AFTER using the pump, it's obvious that the pump vacuum is placing a torsion on some fleshy part that doesn't like it. Question is....which part.
After a prostatectomy, you only have the kidneys, ureter, bladder, urethra, and penis.
Which of those parts is most likely to be affected by a vacuum?
Based on your description, it would seem that the bleeding is coming from either the bladder, ureter, or kidneys. The ureter is a very small tube which leaves it less likely to be collapsed by a vacuum. (so there goes my first thought) The bladder has a much larger surface area, so it would seem most likely to be affected. I'm not sure about the kidneys, but my gut reaction is that they would not likely be the source. The ureter is much longer than the urethra, which would allow for a higher static drop in vacuum, assuming there would be some flow involved.
My best guess is bladder....but what do I know? A docter I'm not. I don't even make a good DumbA** engineer.
