I can't answer your specific question about that Arizona facility, but I wish you the best in finding a solution that will offer you the relief that you want.
Reading between the lines, you have already researched or have been told about different available treatments for BPH. Let me mention an information source you might like to consult if you haven't already:
National Center for Biotechnology Information
Parsing out the URL hidden behind the link language:
NCBI: National Center for Biotechnological Information
NLM: National Library of Medicine
NIH: National Institutes of Health
GOV: I think we all know these guys...
Just search for Urolift or BPH Treatment on the home page. Or, maybe simpler, use a search engine you trust and look for Urolift, then pick out the entries that have ncbi in the URL. A lot of the reported articles will be written in heavy-duty medicalese, but a lot of what is relevant in these articles can be puzzled out with focused reading.
Judging from a couple of articles I found, the Urolift procedure is about as effective as the TURP process, which the older among us may remember is what President Reagan underwent back in the 1980s. Urolift is more expensive. There are also a couple of recent treatments involving localized heat treatment which may be worth considering. Get your doctor's input on those.
Good luck.
