Several possibilities can lead to this. This can include infection, scarring, or anatomical abnormalities.
Infection can be evaluated with appropriate urine tests and a prostate evaluation. Any prostatic fluid can be sent for culture and analysis. A transrectal ultrasound can be done to evaluate for abscess or prostate abnormalities.
If infection has been ruled out, a cystoscopy can be done to evaluate for urethral strictures or scarring.
These options can be discussed with a urologist.
Followup with your personal physician is essential.
