Treatment of Penile Swelling and Bruising
The treatment approach depends critically on the underlying cause: if penile fracture is suspected (history of trauma with snapping sound, immediate detumescence, ecchymosis, and swelling), immediate surgical exploration and repair is mandatory; otherwise, conservative management with observation, NSAIDs, and avoidance of sexual activity is appropriate.
Initial Diagnostic Approach
Suspect Penile Fracture When:
- Patient reports penile ecchymosis, swelling, cracking or snapping sound during intercourse or manipulation, and immediate detumescence 1
- Physical examination reveals swollen, ecchymotic, and potentially deviated penis 2
- Most patients describe a cracking or snapping sound followed by immediate detumescence, along with penile pain and possible penile angulation 1
Evaluate for Concomitant Urethral Injury:
- Must perform evaluation for urethral injury if blood at urethral meatus, gross hematuria, or inability to void is present 1
- Options include urethroscopy or retrograde urethrogram; neither method is superior 1
- Bilateral corporal body fracture is an additional risk factor for urethral injury 1
Treatment Algorithm
For Confirmed or Suspected Penile Fracture:
Surgeons should perform prompt surgical exploration and repair 1. This is a Standard recommendation with Grade B evidence strength.
- Repair is performed by exposing the injured corpus cavernosum through either a ventral midline or circumcision incision 1
- Tunical repair is performed with absorbable suture and should be performed at the time of presentation to improve long-term patient outcomes 1
- A degloving procedure provides the best exposure for blunt and penetrating trauma 3
- Saline injection can show additional corporeal body and/or urethral pathology and assess the integrity of repair 3
For Equivocal Cases:
- May perform ultrasound in patients with equivocal signs and symptoms 1
- MRI can be considered when ultrasound is equivocal 1
- If imaging is equivocal or diagnosis remains in doubt, surgical exploration should be performed 1
For Non-Traumatic Penile Swelling and Bruising:
Consider Alternative Diagnoses:
- Penis friction edema: Results from traumatic disorder of lymph drainage, manifests as local or total penile edema or cordlike congestion of lymphatic vessels 4
- Isolated rupture of deep dorsal vein: Has essentially the same presentation as corpus cavernosal rupture with sudden onset of pain, swelling, and ecchymosis during sexual intercourse 5
Conservative Management:
- Temporary abstinence from sexual intercourse is the primary treatment for friction edema 4
- Diagnosis is by exclusion after infectious and obstructive causes have been eliminated 4
- The swelling typically disappears during several weeks of abstinence 4
For Treatment-Related Penile Swelling:
Minor Penile Swelling from Intralesional Interferon α-2b:
- Can be effectively treated with over-the-counter nonsteroidal anti-inflammatory medications 1
- Symptoms typically last less than 48 hours 1
- Oral hydration is helpful to mitigate these transient symptoms 1
Penile Bruising from Intralesional Verapamil:
- Penile bruising is a known potential adverse event along with dizziness, nausea, and pain at the injection site 1
- Patients should be counseled about these potential adverse events prior to beginning treatment 1
Critical Pitfalls to Avoid
- Do not delay surgical intervention for suspected penile fracture: Prompt surgical repair at the time of presentation improves long-term patient outcomes 1
- Do not miss concomitant urethral injury: Always evaluate for urethral injury when blood at meatus, gross hematuria, or inability to void is present 1
- Do not assume all penile swelling and bruising is fracture: Consider alternative diagnoses like friction edema or isolated dorsal vein rupture, which may be managed conservatively 4, 5
- Patients may delay admission due to fear and embarrassment: Maintain high clinical suspicion even with incomplete history 2
Expected Outcomes with Appropriate Management
- At follow-up after surgical repair of penile fracture, 35 of 40 patients (87.5%) reported erection adequate for intercourse without erectile or voiding dysfunction 3
- Only 2 patients had mild curvature as a complication 3
- Conservative management of friction edema results in complete resolution with abstinence 4
