My wife attended all of my visits with the uro along with me.
She and I were just discussing this thread, and she said she can't imagine any questions she would have hesitated to ask simply because I also happened to be in the room.
In fact, she asked many of the questions, probably partly due to the fact that she's a registered nurse and was more tuned in to things more than I was at that point.
But, regardless of that, whether it concerned life expectancy, mortality risk, sexual side effects, catheter care.....I just can't think of anything that she would have hesitated to ask about, or that I would have cared if she had asked about, or that the doctor would have hesitated to answer, whether it was her asking the question or me asking it.
I know every marriage has different dynamics, but clearly there are things the husband and wife BOTH need to know, and somebody needs to ask the appropriate questions if the information isn't forthcoming.
That being said, I don't think it would be appropriate to schedule a meeting without your husband. I would think that arrangement would make any urologist extremely uncomfortable.
Right now, I think you should be feeling very good about his PSA of <.1, and I would interpret the doctor's statement that he would be on Firmagon "for the rest of his life" as meaning, hopefully, for many, many years.
Have you told your husband the level of anxiety these "unknowns" are causing you? He may not be aware of that. Don't fall into the Donald Rumsfeld trap. Maybe you remember the famous quote by the former Secretary of Defense: "There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns---there are things we do not know we don't know."
Try not to worry about those "unknown unknowns."
