Someone asked a question about how much of the prostate is removed by PVP.

Although I don't have an answer based on measurements of the prostate before
and after PVP,  I did some calculations using PSAs before and after PVP to
come up with an estimate.

Before PVP my prostate was measured using TRUS at about 74 grams and my PSA
was 3.0  Dividing PSA by the volume (74 cc) gives a PSA density of 0.04

One year after my PVP my PSA dropped to 1.6

Assuming that the PSA density remained constant before and after the PVP
(don't know if this is a correct assumption),  would say that my prostate is
now  about 40 grams.  This would be a little more than half of what it was.

So from this crude estimate, I would venture to say that about half of the
inner material of the prostate is vaporized by a PVP.
