Treatment of Orchitis
The recommended treatment for orchitis is ceftriaxone 250 mg IM in a single dose PLUS doxycycline 100 mg orally twice a day for 10 days, along with supportive measures including bed rest, scrotal elevation, and analgesics until fever and local inflammation subside. 1
Diagnostic Approach
Before initiating treatment, proper diagnosis is essential:
- Rule out testicular torsion (surgical emergency) - especially in adolescents with sudden onset of severe pain 1
- Perform laboratory tests:
- Gram-stained smear of urethral exudate or intraurethral swab
- Culture or nucleic acid amplification test (NAAT) for N. gonorrhoeae and C. trachomatis
- First-void urine examination for leukocytes
- Urine culture and Gram-stained smear
- Syphilis serology and HIV testing 1
Treatment Algorithm Based on Likely Etiology
For orchitis most likely caused by sexually transmitted infections (men <35 years):
- First-line treatment:
For orchitis most likely caused by enteric organisms (men >35 years) or for patients allergic to cephalosporins/tetracyclines:
- Alternative treatment:
Note: Rising fluoroquinolone resistance in enteric organisms (particularly E. coli) may limit the effectiveness of these alternatives in some regions 4
Supportive Measures (Essential for All Patients)
- Bed rest until fever and local inflammation subside
- Scrotal elevation to reduce pain and swelling
- Analgesics for pain management
- Adequate fluid intake with medications 1
Follow-Up and Monitoring
- Reassess within 3 days of treatment initiation
- Failure to improve within 3 days requires reevaluation of both diagnosis and therapy 2, 1
- Persistent swelling and tenderness after completing antimicrobial therapy requires comprehensive evaluation for other conditions (tumor, abscess, infarction, testicular cancer, TB, fungal epididymitis) 1
Special Considerations
- HIV-infected patients: Same treatment regimen as immunocompetent patients, but be aware that fungi and mycobacteria are more likely causes in immunosuppressed patients 2, 1
- Hospitalization criteria: Consider for patients with severe pain, high fever, or concerns about medication compliance 1
Partner Management
- Sex partners should be referred for evaluation and treatment if contact occurred within 60 days preceding symptom onset
- Patients should avoid sexual intercourse until they and their partners complete therapy and are symptom-free 1
Treatment Complications and Pitfalls
- Failure to differentiate from testicular torsion can lead to testicular loss
- Inadequate treatment may result in complications such as infertility, chronic scrotal pain, abscess formation, and testicular infarction
- Complete adherence to the full course of antibiotics is critical to prevent complications 1
