Immediate Evaluation and Management of Pediatric Penile Trauma
This 3-year-old requires urgent clinical examination under adequate lighting to assess for corpus cavernosum rupture or urethral injury, and if there is significant swelling, ecchymosis, or inability to void, immediate ultrasound and urology consultation are mandatory.
Initial Assessment
The presence of swelling AND discharge after blunt penile trauma is concerning for serious injury. You need to immediately determine:
- Voiding status: Can the child urinate? Is there blood in the urine or at the meatus?
- Ecchymosis pattern: Look for "eggplant deformity" (dark purple discoloration suggesting corpus cavernosum rupture) or localized bruising
- Penile deviation or angulation: Suggests albugineal tear
- Nature of discharge: Blood from meatus indicates urethral injury; serous fluid may indicate skin injury only
Critical Decision Point: Does This Need Emergency Surgery?
HIGH-RISK features requiring immediate urology consultation 1:
- Inability to void or blood at meatus (urethral injury)
- Significant ecchymosis with penile swelling
- Palpable defect in penile shaft
- Penile deviation or deformity
Why this matters:
Corpus cavernosum rupture is a true urologic emergency even in children. Delayed recognition leads to permanent erectile dysfunction, penile angulation, fibrosis, and abscess formation 2. While rare in prepubertal children, blunt trauma from falls or crushing injuries can cause this injury 2, 3.
Recommended Workup
Ultrasound is your primary imaging modality 1, 4:
- Can detect discontinuity of the tunica albuginea (the key finding in corpus cavernosum rupture)
- Identifies intracavernous vs. extracavernous hematoma
- Evaluates testicular integrity if scrotal involvement
- Non-invasive and readily available
Do NOT delay imaging if clinical suspicion is high - the ultrasound should be performed urgently, not scheduled for days later 4.
Management Algorithm
If ultrasound shows corpus cavernosum rupture:
- Immediate surgical exploration and repair (within hours, not days)
- Flexible cystoscopy to rule out urethral injury 2
- Primary repair has excellent outcomes when performed early 2, 3
If ultrasound shows only superficial hematoma/skin injury:
- Conservative management with ice, elevation, NSAIDs
- Close follow-up in 24-48 hours
- Strict return precautions for inability to void, worsening swelling, or fever
If urethral injury suspected (blood at meatus, inability to void):
- Do not attempt catheterization
- Immediate urology consultation
- May require retrograde urethrography or cystoscopy 1
Common Pitfalls to Avoid
- Dismissing injury as "just bruising" in a young child - corpus cavernosum rupture can occur in prepubertal boys from blunt trauma 2
- Delaying imaging - early diagnosis dramatically improves outcomes 2, 4
- Blind catheterization when urethral injury is possible - can convert partial to complete urethral disruption
- Inadequate examination - examine under good lighting with parent present; sedation may be needed for thorough assessment in a distressed toddler
Additional Considerations
Given the mechanism (relative jumping on penis), ensure:
- Injury pattern is consistent with stated mechanism - while most pediatric genital trauma is accidental 3, 5, document carefully
- No other injuries - examine abdomen, pelvis, perineum
- Tetanus status is current if skin broken
The discharge you're seeing could represent urethral injury, skin laceration, or crushed tissue. This cannot be triaged by phone or observation alone - physical examination and likely ultrasound are required to rule out serious injury 1, 2.
