Hi R&H,
I have not been in your position as I went straight to a prostatectomy, so I can't offer much advice. However, to keep this thread near the top of the 'recent conversations' list I have replied and so hope someone with the relevant experience does reply.
Equally, I don't know how to search on here, but hopefully someone can put that information in a reply. Then you might be able to find more information on your specific topic.
