Here is a comprehensive overview of the treatment of testicular swelling and pain (acute scrotum):
Testicular Swelling and Pain: Evaluation & Treatment
Step 1 — Rule Out Surgical Emergency First
Testicular torsion must be excluded before anything else. It is a time-critical surgical emergency.
| Feature | Testicular Torsion | Epididymo-orchitis |
|---|---|---|
| Onset | Sudden, severe | Gradual |
| Age | Adolescents (peak) | Any age (esp. sexually active adults) |
| Cremasteric reflex | Absent | Present |
| Fever/dysuria | Rare | Common |
| Urinalysis | Normal | May show pyuria |
| Doppler US | Absent/reduced blood flow | Increased blood flow |
If torsion cannot be excluded clinically → immediate urological referral / surgical exploration. Viability is time-dependent: >90% salvage if detorsed within 6 hours; <10% after 24 hours.
Common Causes & Their Treatment
1. Testicular Torsion
- Treatment: Emergency surgical exploration → manual detorsion + bilateral orchiopexy
- Orchiectomy if testis is non-viable
- Do NOT delay for imaging if clinical suspicion is high
2. Epididymitis / Epididymo-orchitis
The most common infectious cause. The spermatic cord is typically tender and swollen; inflammation begins in the epididymal tail and may spread to the testis (Sexually Transmitted Infections, p. 101).
Antibiotic Regimens (CDC Guidelines):
| Clinical Setting | Regimen |
|---|---|
| STI likely (< 35 yrs, sexually active) | Ceftriaxone 500 mg IM single dose + Doxycycline 100 mg PO BD × 10 days |
| Enteric organisms likely (> 35 yrs, insertive anal sex, urinary tract abnormality) | Levofloxacin 500 mg PO OD × 10 days OR Ofloxacin 300 mg PO BD × 10 days |
| Gonorrhoea suspected | Ceftriaxone 500 mg IM + Doxycycline 100 mg BD × 10 days |
Supportive measures:
- Scrotal elevation (reduces pain by improving venous drainage)
- NSAIDs (ibuprofen, diclofenac) for analgesia and anti-inflammation
- Bed rest during acute phase
- Ice packs to scrotum
3. Orchitis (Viral — Mumps)
- No specific antiviral treatment
- Supportive: bed rest, scrotal support, NSAIDs/analgesics, ice packs
- Corticosteroids are controversial; not routinely recommended
- Interferon-alpha has been investigated but not standard practice
- Monitor for atrophy and infertility (occurs in ~30% of post-pubertal cases)
4. Torsion of Appendix Testis
- Usually self-limiting
- Treatment: NSAIDs, scrotal support, rest
- Surgical excision if pain is persistent or severe
5. Trauma (Haematoma / Contusion / Rupture)
- Minor contusion: conservative (ice, elevation, analgesia, rest)
- Testicular rupture: surgical exploration and repair urgently
- Haematocele: may require surgical drainage if large
6. Varicocele
- Scrotal support, analgesics for symptomatic relief
- Surgical or radiological intervention (varicocelectomy / embolisation) if: persistent pain, infertility, or significant grade
7. Hydrocele
- Observation if asymptomatic
- Aspiration (temporary, often recurs) or surgical repair (hydrocoelectomy) for persistent/large symptomatic cases
8. Inguinal Hernia (Incarcerated/Strangulated)
- Surgical emergency — urgent reduction or repair
9. Idiopathic Scrotal Oedema / Henoch-Schönlein Purpura
- Supportive care; treat underlying systemic disease
- NSAIDs; steroids for HSP if systemic involvement
General Symptomatic Measures (for all non-surgical causes)
| Measure | Detail |
|---|---|
| Scrotal support | Elevation reduces vascular congestion |
| NSAIDs | Ibuprofen 400–600 mg TDS; Naproxen 500 mg BD |
| Ice packs | 15–20 min intervals, especially in first 48 hrs |
| Rest | Avoidance of strenuous activity |
| Analgesics | Paracetamol ± weak opioids for severe pain |
Key Red Flags → Refer Urgently
- Sudden onset severe unilateral pain (torsion until proven otherwise)
- Absent cremasteric reflex
- No pyuria/urethral discharge (argues against infection)
- Age < 25 years with acute pain
- Palpable scrotal mass (exclude testicular cancer)
Note: Always evaluate any persistent testicular mass for malignancy. Testicular cancer can present with a painless or mildly painful scrotal lump and must not be missed. Scrotal ultrasound is the first-line imaging modality.
