John if your uro rules out the blood clot, as suggested by the other post--  
a smart idea to check that out-- ask him/her about your bloodwork and if
your prostate simply is continuing to expand/grow because he/she has not
addresse the root cause?   Prostates do not necessarily stop growing after
the operation since the operation simply cuts back the obstructive growth
but doesn't address the cause.  If yours is growing quickly you need to find
out what's driving the growth--and it is not necessarily cancer, either, so,
don't panic.    Also, check out my reply post to LUBRO, in answer to "Re:
seeking informationg and help"  of 9/16.

I've made the point before that it is nuts to have the operation--any
operation--without understanding the cause and whether or not the prostate
will keep growing after the operation.  Bloodwork is absolutely necessary,
in my non-medical opinion.  Other things have to be taken into consideration
that drive up estrogens in men which in turn causes rebound effects from the
testosterone,such as: abdominal fat, any alcohol no matter how little,
coffee, hot spices,  meats--especially avoid hormone infested meats--,
pesticides.  If your estradiols are low, but your DHT is high while other
sex hormones are normal, then there might be a thyroid, pituitary, or other
problem that an endocrinologist may be best to diagnose and medicate to stop
the prostate growth and maybe even reverse it...at least that is my hope.
Have you pestered your uro for a complete and frank discussion about your
hormones from your blood tests?  If not, you might want to do so.   But
expect that your uro may be way out of his league when you do ask.   So, you
might need to get to an endocrinologist if your bloodwork shows that your
DHTs are too high.  Best of luck!!
