I too, did a little more digging and what I discovered is that a radical Prostatectomy leaves scar tissue under the bladder where the prostate was. It is very difficult for a surgeon to open the area for a neovagina and sometimes the neovagina must be cut short for about 2 or 3 inches in depth. A TURP on the other hand is only partial removal of the prostate and does not leave significant scar tissue. So, a patient who has had a TURP should have surgery normally.
