With BPH and persistent UTI, that PSA is lower than it could be (I've had a consultant tell me that a UTI can elevate PSA into the hundreds).
The likely relevant issues are...
1 What's the cause and solution to your persistent UTI?
2 You're concerned of the possibility of Pca.
A further PSA test and DRE are likely.
And meds will be reviewed and revised.
In your position, I'd request an MRI and biopsy... which together will help determine the issue of Pca.
I'd not be surprised if the consultant declined.
Your PSA is likely too low to auto-trigger a bone scan.
My opening question might be something skin to 'Why do I have this UTI issue, and is it likely or potentially an indicator of Pca?'
And then listen, and make notes if necessary.
