Having had a ThermatRX procedure 2 years ago (with insufficient results)
I am a candidate for a TURP or PVP.

Usually when a new procedure such as PVP is introduced, after a while an
improved product or procedure is introduced.  Does anyone know if this
has happened with PVP, or is a new and improved version coming and when
it may be available??

I believe the wavelength of the laser has been changed since it first came
out to improve results.

Lee,
Sorry, your answer is not correct.

PVP's wavelength has always been at 532 nanometers what has changed is the
power level.  The power level in the clinical trials was 60 Watts, however,
the commercial version and the version in use since 2002 has been the  80
Watt version.

The present Laserscope "Greenlight" PVP is 80watts at 532 nanometers and is
the "state of the art" version from Laserscope.  I am not aware of what
Laserscope R&D is working on but I don't believe going to a high power level
will improve the procedure.  I believe that 80 Watts at 532 nanometer is
optimum for prostate surgury with little bleeding and heating.

I knew something had changed.  Thanks for setting the record straight.

Bob,
 I am a 50++ male.  I did Thermatrx DOT Sep. 04.  It's no good to me at
all.  I am looking for Greenlight PVP now.  My uro, Dr. C in northern NJ,
told me he has done so many successdul PVP cases.  I am asking for three
references of his past patients, but got no answer after three follow-up in
three weeks. Don't know what to do?  How is your status?

Pat
