There are several factors that determine whether the surgical route will be open or robotic. But size of prostate is one of them. Like Steve said above, often times the prostate volume is reduced with meds to prior to treatment...primarily for the brachy therapy procedure however. Don't know what the upper limit in size of the prostate is for the robotic procedure, but obviously it needs to be small enough to fit through the keyhole incision.
Sorry you had to be here and welcome. Making the decision of what to do will be very difficult, but you will find lots of folks here to provide their take on their treatment plans to guide you.
Good luck and let us know what your final decision will be.
You are beating back cancer, so hold your head up with dignity
