Category I: Acute Bacterial Prostatitis
Acute bacterial prostatitis> is characterized by sudden fever, perineal and suprapubic pain and voiding symptoms. The urine shows signs of a urinary tract infection.
Category II: Chronic Bacterial Prostatitis
Chronic bacterial prostatitis is characterized by symptoms of prostatitis (pain, voiding symptoms) for more than 3 months with recurrent bacterial urinary tract infection.
Category III: Chronic Pelvic Pain Syndrome
The chronic pelvic pain syndrome (CPPS) is characterized by pain and voiding symptoms for more than 3 months, without detection of bacterial pathogens using standard microbiological methods. The CPPS is divided into two subcategories:
Category IIIA: Inflammatory CPPS
The inflammatory CPPS is characterized by a chronic pelvic pain syndrome with signs of prostate inflammation (leukospermia or white blood cells in expressed prostate secretion). The culture of semen, EPS and urine after post-prostatic massage are negative.
Category IIIB: Noninflammatory CPPS
The noninflammatory CPPS is characterized by a chronic pelvic pain syndrome without signs of prostatic inflammation (see category IIIA).
Category IV: Asymptomatic Inflammatory Prostatitis
Patients with asymptomatic inflammatory prostatitis have evidence for prostate inflammation (leukospermia, white blood cells in expressed prostate secretions, positive cultures or inflammation in tissue biopsies) without pelvic pain or voiding symptoms.
