In prostate cancer different points of view from professionals are highly important because there are so many options, different levels of seriousness of the case and different natures of cases, and different levels of expertise among doctors. Rather than getting another opinion from a urologist, you could check with a radiation oncologist or a medical oncologist, or, better, both!
Sorry, can't help you with the Tucson talent, but you could see what Us Too has published. Us Too, a non-profit organization, is the largest prostate cancer support and education organization, and it can tell you about locations of its chapters. I'm sure there is one in Tucson. Participants or the chapter leader would probably know quite a bit about the local doctors.
Take care,
Jim
