Basically the urethra is a "tube", that transports the urine from the
bladder, on its journey it passes through and is surrounded by the
prostate, continues through the penis and out. When the prostate
enlarges it exerts pressure on the urethra, and causes the lumen to
diminish (collapse), making it difficult to void. All of these current
procedures whether microwave, PVP, TURP, result in the destruction of
the urethra, at the point where it is surronded by the prostate. In
order to destroy the enlarged prostate, you must first go through the
ureathra, and destroy that also. A new channel is created, which will
fill in again by the re-growing prostate if you live long enough. Little
has been said as to what causes the prostate to enlarge, and possible
treatments directed not at destroying, but directed at stopping
enlargement. Cannot help but feel that not only is the urethra dstroyed,
but the rectum can also be traumatized.
Wondering if any research has been done using the "medicated" stents in
the urethra, similiar to those used in the coronary artery's.
