Sorry I'm a bit late to this thread but for what it's worth, I've heard good things about the Royal and the surgeons there.
I met with one of the surgeons who was instrumental in bringing RARP procedures to the region and I found him to be honest and impressive in equal measure. I actually ended up having Brachytherapy but had I decided on surgery, I would have been more than happy to have been under the care of the Royal. I also have a friend who had surgery under the same consultant I met and he's had very good results and couldn't speak highly enough about the after care and the specialist nurse team at the Royal.
