It was at least half joking, but I am genuinely curious how the finger in his ass would straighten the urethra. Is it the internal part of the urethra that needs straightening, and if so, can you really just push it around from the anus like that?

The part of the urethra that passes through the prostate is usually bent. As I said, I'm only guessing, but I think by angling the penis down and pushing the prostate forward from behind, it should make it less of a sharp angle for the scope to pass through, therefore reducing pain and risk of urethral injury.
