Your symptoms, A and E visit, catheter, high PSA (mine was 29) are pretty much identical to mine. I was age 53. My doctor was a bit more proactive. As Barry says, this is a slow growing cancer, a month will make no difference, if you have PCa you have probably already had it for a couple of years, and it is still almost certainly curable.
Did anyone do a PSA test 7years ago? If you have some PSA results to compare over a period of time, it is far more useful than just one result.
If the next PSA test shows a reading of more than 4.0 then I would expect a referral to urology. We have had someone who's PSA was 70 and they did not have cancer, so it is by no means certain you have it.
