Sorry you join us due to your concern that your husband may have PCa. Your GP was right to refer him to urology because apart from the DRE which was not commented on a PSA of 130 means a high chance of PCa possibly but not necessarily advanced.
I would suggest that your husband learn as much as he can about his situation. He could have asked his GP whaat he thought about his DRE for example. Hubby shouldn't be afraid to ask questions of his consultants and it can be helpful to have somebody accompany him at appointments, particularly when all tests and scans have been done and he is given a diagnosis (assuming it is PCa).
Treatment options can depend on how far PCa is advanced and other factors. Naturally, if PCa is found at an early stage there is a better chance of radical treatment being successful but there are systemic restraining treatments where cancer is more advanced so hubby is still likely to be with you for a long time.
It is now more generally thought best to have a MRI first rather than biopsy first and then MRI but some hospitals still offer the biopsy first and if this is proposed he could strongly argue for the MRI first. A template biopsy is more involved than a TRUS but is more accurate and less likely to cause an infection. If PCa is diagnosed, hubby will be offered treatment options after his case has been discussed by a MDT (Multi Disciplinary Team.). I suggest you download or obtain a hard copy of the 'Toolkit' from the publications dept of this Charity. It provides a lot of helpful information about the disease and possible treatments so when the time comes hubby is better able to grasp the options available to him ,together with pros and cons of these treatments as a treatment decision may be left to him.
