There are prices, and then there are prices.  I had something similar
to what you describe.  As is common with medicine in the USA, the
price depends on your insurance coverage ('billed' vs. 'covered'
below), and I don't have to pay the difference between them.  I
guess 'billed' is what the poor people with no insurance pay, if
ANYONE actually pays that.  

My GP thought my prostate was hard and had a lump, and after the
initial office visit where the Uro concurred, he wanted the needle
biopsy.  It appears I don't have a problem.  PSA 0.8, 14 months
later, still 0.8, and normal results from the biopsy.  The followup
visit mostly consisted of giving me the results, checking my urine
again, and making sure I didn't have lasting effects from the biopsy
(infection, blood in urine, pain, etc.).  I did have a little bit
of blood in my urine for a couple of days.  There wasn't much pain,
only briefly during the surgery, and even then not much.

I'm a Canadian and plan to go to North Dakota for a Urologist to do a
ultrasound and a biopsy on the prostate.
I just need the findings, treatment will be done back home. Someone
suggested about $ 2500 US , does this sound in the range ? Thanks ( the
waiting period at home is 2 months, ridiculous )
