Overview
Infective epididymitis is an inflammatory condition of the epididymis, often caused by bacterial or, less commonly, chlamydial infections, leading to symptoms such as scrotal pain, swelling, and tenderness. 14Diagnosis
Clinical Presentation: Scrotal pain, swelling, and tenderness.
Laboratory Tests: Urine cultures (21% positive in one study 1); consider serological tests for chlamydia in suspected cases 4.
Imaging: Scrotal ultrasound often confirms diagnosis, showing characteristic changes in 87.3% of cases 1.
Differential Diagnosis: Includes testicular torsion, orchitis, and abscess formation (as seen in xanthogranulomatous cases 2).Management
Antibiotics: First-line treatment typically includes broad-spectrum antibiotics (specific dosing not provided in abstracts; consult local guidelines). For suspected chlamydial infection, consider doxycycline or azithromycin 4.
Supportive Care: Pain management, scrotal elevation, and rest.
Follow-Up: Monitor for recurrence, especially in pediatric patients where 27.4% experienced multiple episodes 1.
Surgical Intervention: Reserved for complications like abscess formation or persistent symptoms unresponsive to medical therapy 2.Special Populations
Pediatrics: Common in pubertal boys with a mean age of 10.92 years; recurrent episodes noted in 27.4% of cases 1.
Comorbidities: Diabetes may predispose to severe forms like xanthogranulomatous epididymitis 2.Key Recommendations
Diagnose using clinical presentation and imaging, with urine cultures when available (Evidence: Moderate 1).
Initiate broad-spectrum antibiotics as first-line treatment, tailoring to culture results or suspected pathogens (Evidence: Moderate 14).
Monitor pediatric patients closely for recurrence due to higher risk of multiple episodes (Evidence: Moderate 1).
Consider chlamydia testing in sexually active patients with suspected epididymitis (Evidence: Weak 4).
Evaluate for underlying anatomical abnormalities, especially in recurrent cases (Evidence: Moderate 1).References
