What tests before PVP??

I'll be seeing a uro on 1/5. I might or might not have BPH (at one time I
was certain it was that, but the last few months I have had mucho problems
also mimicking prostatitis/cystitis).

Anyway, what tests am I likely in for as part of the dx.

I am male (well...duh...I'd better be), 57 years old.

PSA tests have been quite good (ranges between 1.6 and 2.1 and in fact the
last one in March was slightly less than the one a year earlier) and DRE
exams have been normal. So, I am hoping he does not want to do a biopsy.

Here is what I am guessing, so please comment:

1) DRE of course

2) Maybe another PSA

3) uroflow type test? Possibly a follow-up ultrasound of the bladder to see
about retention?

4) ultrasound of prostate??

5) cystoscopy (most probable)?

I would also welcome comments about the last 2 tests. I had a cystoscopy
about 7-8 years ago. I seem to remember that it was not really painful, but
quite uncomfortable, but also it was quite brief -- the actual scope
procedure after the anesthetic  seemed to last 3-4 minutes. I'm hoping the
procedure has improved to where it involves even less discomfort.

Finally, I've never had an ultrasound (of the prostate). What is that like?
