IMHO and in my case, I have chosen open (RRP) with a surgeon that has done over 2500 and done many RALP.
With high content and high number of hits on biospy, and numerous dx prostatitis (potential scar tissue affecting surgery), this is what I have chosen at this time. His and his dept comments were that IC seems to have better outcome with open than robotic...in cases like mine, particularly.
They usually try to save one if not both nerve bundles during procedure to retain some erectile function in the future. I would rather have that done by a very experienced surgeon open, than one less experienced on robotics.
I was sold initially on robotic. To me, it was tech's got to be better....the better and newer...the better. After a lot of research, the shine came off that thought for me and I had to look at what was best for me. RRP will mean a longer recovery time than RALP. That is fine with me if I have a chance at better IC and perhaps ED...again...in my case...and with a very experienced surgeon having solid knowledge of both techniques.
If I had 1%-5% on one core of 8 or 12 or saturation, it would still be cancer. However, I would have more time to think of treatment and when...and would have chosen active survellience for at least the short term (other imaging and more biopsies) while I reviewed my options again.
My nickel's worth.
