Seminal fluid analysis in chronic prostatitis/chronic pelvic pain syndrome*

[Symptomatic approach to chronic prostatitis/chronic pelvic pain syndrome]

OBJECTIVE

To review the diagnosis and pathogenesis of chronic prostatitis (CP) and chronic pelvic pain syndrome (CPPS).

MATERIAL AND METHODS

A review of the literature was performed by searching the Medline database (National Library of Medicine). Search terms were either medical subject heading (MeSH) keywords (microbiology, pelvic pain, prostatitis) or terms derived from the title or abstract. Search terms were used alone or in combinations by using the "AND" operator. The literature search was conducted from 1990 to the present time.

RESULTS

Chronic bacterial prostatitis is a chronic, recurrent bacterial infection of the prostate, accounting for about 5 to 10% of all cases of chronic prostatitis (CP). CPPS is nonbacterial genitourinary pelvic pain present for at least 3 months, sometimes associated with sexual and voiding disorders. Although the prostate does not appear to be involved in all cases of chronic pelvic pain in men, the term CP usually remains associated with CPPS (CP/CPPS). CP/CPPS has a negative impact on quality of life. The precise pathogenesis of CP/CPPS has not been elucidated, but prostatic infection and inflammation could be involved, not as direct causes, but as initiating factors of a neurological hypersensitization phenomenon. Evaluation of CP/CPPS comprises clinical interview completed by the National Institutes of Health-Chronic Prostatitis Symptom Index questionnaire (NIH-CPSI), physical examination, urine culture and uroflowmetry combined with determination of the post-voiding residual volume. The other investigations are optional and are designed to exclude other urological diagnoses. The Meares-Stamey four-glass test should be abandoned in favour of a simplified test comprising urine analysis before and after prostatic massage. However, the indications for this test are limited to patients in whom chronic bacterial prostatitis is suspected or with bacteriuria on urine culture.

CONCLUSION

Chronic bacterial prostatitis represents only about 5 to 10% of all cases of CP. The usual terminology of chronic non-bacterial prostatitis has been replaced by the term CPPS or CP/CPPS in men, in order to situate this disease in a broader context not exclusively related to the prostate. Despite its prevalence and its impact on quality of life and sexuality, CP/CPPS remains poorly known and continues to raise diagnostic problems.

UREAPLASMA UREALYTICUMINFECTION RELATED TO SEMINAL PLASMA IMMUNOSUPPRESSIVE FACTORS, SEMEN PH AND LIQUEFACTION DURATION

In this study, semen samples from fertile and unexplained infertile men were explored for relationships between seminal plasma immunosuppressive factors (SPIFs), semen pH, liquefaction duration and infection of ureaplasma urealyticum (Uu). SPIFs activity was measured by way of counteracting complement. PH was detected by exact pH test paper. Liquefaction duration was observed at 37 degrees C. The results showed that Uu infection ratios of semen samples with abnormal SPIFs, pH or liquefaction duration were markedly higher than those of normal semen samples. It is suggested that Uu infection decreases the level of SPIFs, changes the pH in semen and prolongs the semen liquefaction so as to cause spermatic quality decline. The enhancement of SPIFs level may change the male body against Uu infection.

[Classification, etiology, diagnosis and treatment of prostatitis. Other types of prostatitis. Acute and chronic prostatitis]

Prostatitis is a highly prevalent nosologic entity and hence has an enormous financial impact on health systems as well as negative repercussions on patients' quality of life. The symptoms are ambiguous, diagnostic methods are controversial and treatments are long and produce inconsistent results; consequently, although not life-threatening, prostatitis has become one of those diseases that is difficult both for the patient and for the physician who attempts to help, sometimes without success. Although an infectious etiology is accepted in most cases, there are major controversies about both the diagnostic methods used and their interpretation. Recently the National Institutes of Health in the USA has proposed a new classification of this disease to substitute that used for the last twenty years. This new classification may provide a more effective approach to the diagnosis and treatment of this insidious disease.
