Hi Captain Bob
Sorry to hear that you are in this situation.
My Robotic op was May 2013 and I was told then that if I opted for anything other than the op first it was off the table for any future salvage treatments. Since then apparently even though treatments may make the gland squishy, "squishy" is the Latin medical term, and more difficult to remove intact there have apparently been advances in techniques.
If your Urologist is confident, and if you are confident in her or him, go for it. What have you got to lose?
You are facing the decisions that we all face when first diagnosed and confronted with PCa, and that is a choice between potentially extended life with consequences, or less life.
If it were me facing the choice you are facing I would look at my life expectancy according to family history. Bluntly, if your likely life expectancy is a few years then maybe you would opt for another treatment option rather that take the chance on the potential side effects? Ot you may choose no treatment?
Whatever you choose a potential consequence of your treatment is LIFE. Incontinence can be lived with, if you are alive in the first place.
