Tuberculous prostatitis

Area of Science:

• Urology
• Infectious Diseases
• Pathology

Background:

• Tuberculosis prostatitis is a rare but serious condition.
• Diagnosis can be difficult due to non-specific symptoms and challenges in tissue sampling.

Purpose of the Study:

• To evaluate the diagnostic yield of needle biopsy in tuberculosis prostatitis.
• To identify factors influencing the detection of Mycobacterium tuberculosis in prostatic tissue.

Main Methods:

• Retrospective analysis of 5 patients diagnosed with tuberculosis prostatitis.
• Review of histopathological findings, including caseation and granuloma presence.
• Assessment of special stains and culture results from biopsy specimens.

Main Results:

• Noncaseating granulomas were more frequently identified than caseating lesions on needle biopsy.
• Absence of caseation did not exclude tuberculosis.
• Special stains for acid-fast bacilli were often negative, potentially due to small sample size.

Conclusions:

• Needle biopsy may not reliably detect caseating granulomas in tuberculosis prostatitis.
• A high clinical suspicion warrants further investigation even with negative initial biopsy findings.
• Repeat biopsy for microbial culture is recommended when noncaseating granulomas are found and tuberculosis prostatitis is suspected.
