Pathogen Detection and Diagnostic Scenarios in Chronic Prostatitis

Area of Science:

• Urology
• Microbiology
• Infectious Diseases

Background:

• Chronic prostatitis (CP) presents with pelvic pain, urinary, and sexual dysfunction, often lacking clear infection signs, complicating diagnosis.
• The NIH 4-glass test is standard, but some negative tests respond to antibiotics, suggesting missed infections.
• This study compares diagnostic methods for pathogen detection in CP patients.

Purpose of the Study:

• To compare the effectiveness of four lower genitourinary tract diagnostic methods for detecting causative pathogens in chronic prostatitis (CP) patients.
• To evaluate two simplified two-specimen tests.
• To identify the optimal diagnostic approach for CP.

Main Methods:

• Retrospective study of CP patients (18-59 years) using NIH criteria.
• Comparison of Meares-Stamey 4-glass, 2-glass pre-post-massage, 5-glass, and VB2-semen tests.
• Statistical analysis using ANOVA and Pearson's chi-squared tests for diagnostic outcomes and pathogen detection rates.

Main Results:

• Five-glass and VB2-semen tests showed similar detection of Gram-negative pathogens as 4-glass and 2-glass tests.
• Five-glass and VB2-semen tests detected significantly higher percentages of Enterococci.
• Semen-inclusive tests identified a broader spectrum of pathogens, including more sexually transmitted ones.

Conclusions:

• Diagnostic tests incorporating semen samples are superior for detecting Gram-positive (e.g., Enterococci) and sexually transmitted pathogens in CP.
• Integrating semen samples into the standard 4-glass test can enhance diagnostic accuracy.
• Improved diagnostics can lead to more targeted antibacterial treatment for chronic prostatitis.
