Epididymitis and Orchitis (Children)
โ ๏ธ Always exclude testicular torsion as a differential. If in doubt โ urgent surgical referral. ๐
๐ฆ Causes
- ๐ Epididymitis:
- ๐งซ Bacterial (UTI organisms: E. coli, Klebsiella, Proteus).
- ๐ฆ STIs in young men (Chlamydia, Gonorrhea).
- โฉ๏ธ Urinary reflux into vas deferens (e.g., posterior urethral valves).
- ๐ฅ Trauma to the scrotum.
- ๐ Orchitis:
- ๐ฆ Viral (mumps โ especially post-pubertal boys).
- ๐งซ Bacterial (often secondary to epididymitis or STI-related).
๐ค Clinical Features
- ๐ Epididymitis:
- Gradual onset of scrotal pain & swelling.
- Red, warm, tender epididymis (pain may radiate to groin/abdomen).
- ยฑ Fever, dysuria if UTI-related.
- ๐ Orchitis:
- Sudden painful swollen testis.
- Tenderness, erythema, systemic symptoms (fever, malaise).
- Often follows mumps infection โ can cause epididymo-orchitis.
๐ฌ Investigations
- ๐ Epididymitis:
- Urinalysis & culture (look for leukocytes, nitrites).
- STI screen in adolescents/young men.
- Scrotal US: enlarged epididymis, โ blood flow.
- Bloods: CBC (โ WCC).
- ๐ Orchitis:
- Scrotal US: exclude torsion, assess abscess.
- Urine/STI tests if bacterial suspected.
- Mumps IgM serology if viral cause suspected.
๐ Management
- ๐ Epididymitis:
- Empirical antibiotics (e.g., ceftriaxone + doxycycline for STI; co-amoxiclav/ciprofloxacin if UTI).
- NSAIDs, scrotal elevation, bed rest.
- Hydration; surgery only if abscess.
- ๐ Orchitis:
- Supportive care (NSAIDs, scrotal support, ice packs).
- If bacterial โ antibiotics as above.
- Mumps orchitis โ supportive only (no antivirals).
- Follow-up: monitor for testicular atrophy or abscess.
๐ Key exam tip: Epididymitis = gradual onset, often UTI/STI.
Orchitis = sudden onset, often viral (mumps).
Always rule out torsion. ๐จ
