Concerned about father's PSA level

My father (66 years old) PSA has been elevated since Feb 2006. In 2006, it was 16 and in June 2007 it is 15. The free PSA in June 2007 is 11%
Six months ago (december 2006), he had Digital Rectum exam (DRE) and Ultrasound and the reports were normal. His prostate was reported slightly enlarged.
After PSA test in June 2007, he also did Urine culture and he has UTI infection.
Is the elevated PSA due to Urine infection? Should he go for another PSA test after taking antibiotic course and making sure he has no UTI infection?
Is biopsy necessary for him?
Is it good to go for a biopsy, while UTI infecion (infection) is still there? Or should he go for a biopsy after UTI infection has cleared up?

An elevated PSA can be caused by prostatitis, which on urinalysis can present similarly to a UTI.  

However, before attributing it to that, you have to rule out prostate cancer.  Either approach is fine.  Some urologists would prefer to have the UTI clear and then repeat the PSA test to see if the level has decreased.

In any case, a biopsy should be done regardless.

Followup with your personal physician is essential.
