Hi thank you for chiming in! Yes I too am a retired doc, an orthopedist actually. So I was a carpenter, not a plumber 🙂 And I don't pretend to know anything about plumbing, But I do know some things about how this business works in general and let me tell you it is NOT fun being on the other side of things. You have to fight for yourself as 'beachflyer' described very well in his earlier post. You cannot take anything for granted and you cannot assume anything. It's rarely the same from case to case as this is such a grey area with this stuff.
So thankfully I do have a urologist friend or 2 and yes they do say the same thing namely that MRI is what they give the greatest weight to. So my diagnosis is also BPH but because of the positive Exo and strong family history close monitoring is advised. They were actually going to wait a year before redrawing the PSA. I said no I'm not waiting a year I want it redrawn at 6 months which will be Nov, so not far from now. The MRI was end of July. And the urine test was done 2 months before the MRI . So I feel ok about it for now. Then if there is any question with the updated PSA I will request a biopsy with or without a repeat MRI.
Hope that helps!
