Summary
Transrectal ultrasonography aids in diagnosing prostatic abscesses and guiding drainage. This study highlights sonographic patterns, particularly in melioidosis cases, showing effective treatment outcomes.
Area of Science:
- Urology
- Medical Imaging
- Infectious Diseases
Background:
- Prostatic abscesses are uncommon but serious infections.
- Predisposing factors often contribute to their development.
- Accurate diagnosis and effective treatment are crucial for patient outcomes.
Purpose of the Study:
- To analyze medical imaging findings in patients with prostatic abscesses.
- To evaluate therapeutic strategies for prostatic abscesses.
- To identify characteristic sonographic patterns, especially in melioidosis.
Main Methods:
- Retrospective review of 12 patients with prostatic abscesses.
- Diagnostic procedures included urinalysis, abscess fluid culture, and imaging (TRUS, CT, MRI).
- Therapeutic options involved transrectal ultrasound-guided drainage or conservative medical management.
Main Results:
- Hypo-echoic masses with internal septation were common imaging findings.
- The primary pathogen identified was B. pseudomallei.
- All abscesses resolved within 4 weeks, irrespective of size or pathogen, with effective drainage.
Conclusions:
- Transrectal ultrasonography (TRUS) is valuable for diagnosing prostatic abscesses.
- TRUS effectively guides aspiration and drainage procedures.
- Specific sonographic patterns were observed, particularly in cases of melioidosis-induced prostatic abscess.
