Management of Scrotal Bruising
Scrotal bruising requires immediate scrotal ultrasound to differentiate between benign contusion requiring conservative management and testicular rupture requiring urgent surgical exploration.
Initial Diagnostic Approach
The presence of scrotal bruising following trauma mandates urgent imaging evaluation, as clinical examination alone is insufficient to exclude testicular rupture. Scrotal ultrasound is the first-line imaging modality and should be performed in all patients with scrotal trauma 1.
Key Ultrasound Findings That Determine Management:
Proceed directly to surgical exploration if:
- Hematocele is present (blood collection outside the tunica albuginea)
- Disruption of the tunica albuginea is visualized
- Extrusion of seminiferous tubules is seen
- Clinical hematocele is palpable on examination 2
Conservative management is appropriate when:
- Tunica albuginea remains clearly intact
- No hematocele present
- Isolated intratesticular hematoma without rupture
- No fracture planes within the testis 2, 3
Management Algorithm
Surgical Exploration Indicated:
Patients with penetrating trauma or blunt trauma showing testicular rupture on ultrasound require urgent surgical exploration. Early surgical intervention (ideally within 72 hours) achieves the best long-term outcomes for testicular rupture and hematocele 3. Surgical exploration allows for:
- Evacuation of hematoma
- Debridement of necrotic tissue
- Repair of tunica albuginea
- Testicular salvage when >50% viable tissue remains
Conservative Management Protocol:
For isolated intratesticular hematoma without rupture 4, 3:
- Scrotal support and elevation
- Ice application in first 24-48 hours
- Analgesia (NSAIDs unless contraindicated)
- Activity restriction
- Serial ultrasound examinations to confirm resolution 4
- Pain typically resolves within 1-2 days 4
Critical Pitfalls to Avoid
Do not rely solely on clinical examination. Three patients with operatively confirmed testicular rupture presented with only swelling without tenderness 2. The absence of pain does not exclude significant injury.
Do not delay imaging. Patients with massive scrotal swelling require ultrasound to determine testicular status, even when discrete fracture planes cannot always be detected 3.
Monitor for delayed complications. Patients with >30% of testis replaced by necrotic tissue/hematoma may ultimately require delayed orchidectomy despite initial conservative attempts 5.
Special Considerations
Sports-related injuries account for 59% of blunt scrotal trauma cases 5, predominantly affecting males aged 10-30 years. This young demographic makes testicular preservation particularly important for fertility preservation.
Penetrating trauma has different management patterns: These injuries more commonly require surgical intervention (63% vs 21.4% for blunt trauma) and have higher rates of inpatient admission 6. However, orchidectomy rates are similar between blunt and penetrating mechanisms.
The key distinction is that management should be centered on ultrasound findings and pain severity rather than mechanism alone 4. Serial imaging provides objective assessment of resolution and guides the need for delayed intervention.
