Prostatitis; chronic

Definition:

An inflammation of the prostate gland that develops gradually, continues for a prolonged period, and typically has subtle symptoms.

Causes, incidence, and risk factors:

Chronic prostatitis is caused by a bacterial infection. It may be associated with or follow urinary tract infection (cystitis), urethritis, epididymitis, or acute prostatitis. The disorder is diagnosed in 5 out of 1,000 outpatient visits. It is estimated that as many as 35% of men over 50 years old may have chronic prostatitis. Increased risk is associated with men over 30 years old.

Certain factors may predispose a person to develop chronic prostatitis, such as excessive alcohol intake, perineal injury, and certain sexual practises. It is hypothesised that these factors may cause congestion of the prostate gland which produces an excellent breeding ground for various bacteria.
