Certainly prostatitis can cause your symptoms such as lower back pain, urinary odor and urinary urgency.
I would suggest a
digitalDigital rectal exam rectal exam to evaluate the prostate, and to culture any prostatic secretions. There are some cases where 4-12 weeks of antibiotics are necessary. Tests for STDs such as gonorrhea or chlamydia should be performed.
If negative, you may want to consider a transrectal ultrasound to make sure no prostatatic abscesses are present. Another consideration would be a scrotal ultrasound to evaluate for epididymitis.
Followup with your personal physician is essential.
