I was told by pcp that my urinal issue could be from diverticulitis but urine is clean can you have uti symptoms with out bacteria from diverticulits?

Misunderstanding? I think you misunderstood your doctor. I'm sure she knows that diverticulitis cannot cause abnormal urinalysis. If your urine is "clean" i.e. no bacteria, then you don't have a UTI. In any case, UTIs are rare in men your age. Return to your doctor to work this out. Good luck!
