Treatment of Calcifications in Chronic Bacterial Prostatitis
For chronic bacterial prostatitis with prostatic calcifications, treatment should be extended to 12 weeks of antibiotic therapy rather than the standard 6 weeks to improve cure rates and reduce relapse risk. 1
Diagnostic Approach
- Perform the Meares and Stamey 2- or 4-glass test to confirm chronic bacterial prostatitis diagnosis (strong recommendation) 2
- Conduct transrectal ultrasound to identify and evaluate the extent of prostatic calcifications 2, 3
- Perform accurate microbiological evaluation for both typical pathogens and atypical organisms such as Chlamydia trachomatis and Mycoplasma species (weak recommendation) 2
- Digital-processing software can be used to calculate the extension of prostatic calcification area at ultrasound, as higher percentages of prostatic calcification are associated with chronic bacterial prostatitis 3
Antibiotic Treatment
- For patients with prostatic calcifications, extend antibiotic treatment to 12 weeks instead of the standard 6 weeks 1
- First-line therapy options include:
Alternative Antibiotics for Fluoroquinolone-Resistant Cases
- Fosfomycin has shown 82% clinical cure rate at end of treatment and 73% at 6 months for MDR pathogens 1
- Aminoglycosides can be considered as a therapeutic alternative for quinolone-resistant prostatitis 3
- For specific pathogens:
Adjunctive Therapies
- Consider multimodal therapeutic approach by combining:
Treatment Monitoring and Follow-up
- Monitor treatment response through clinical symptom assessment and repeat microbiological testing
- Consider surgical intervention (modified retropubic prostatectomy) for patients with chronic bacterial prostatitis with calcifications who do not respond to extended antibiotic therapy 5
Common Pitfalls and Caveats
- Failure to extend antibiotic treatment duration in patients with prostatic calcifications significantly increases relapse risk 1
- Prostatic calcifications serve as a nidus for bacterial persistence and biofilm formation, making standard 4-6 week antibiotic courses often inadequate 1, 3
- Diarrhea is the most common adverse event (18%) with extended fosfomycin treatment 1
- Fluoroquinolone resistance is increasing (up to 75% in some studies), necessitating alternative antibiotic strategies 1, 3
