The PSA blood test should be done before the DRE. There is concern, but not much evidence that a DRE might cause a raised PSA, but unless it was a particularly brutal DRE, I would not expect any impact 4 days later.
After a once-off unexpectedly high PSA, protocol is to test for a UTI, and if found, that needs to be cleared with antibiotics, and a retest after 6 weeks. Some hospitals require the GP to retest anyway before referral, or they'll reject the referral.
