Management of Penile Fracture
Surgeons should perform prompt surgical exploration and repair in all patients with suspected penile fracture, as this approach significantly reduces long-term complications including erectile dysfunction and penile curvature compared to conservative management. 1
Diagnosis
Clinical Presentation
Suspect penile fracture when a patient presents with the following classic triad 1:
- Cracking or snapping sound during intercourse or penile manipulation
- Immediate detumescence following the injury
- Penile ecchymosis and swelling
Additional findings may include penile pain and penile angulation 1.
Diagnostic Imaging
- History and physical examination alone are often sufficient for diagnosis in patients with classic presenting symptoms 1
- Ultrasound may be performed in patients with equivocal signs and symptoms, as it is widely available, low cost, and provides rapid results 1
- MRI can be considered when ultrasound findings are equivocal 1
- If imaging remains equivocal or diagnosis is uncertain, proceed directly to surgical exploration 1
Evaluation for Urethral Injury
Mandatory evaluation for concomitant urethral injury is required in patients presenting with 1:
- Blood at the urethral meatus
- Gross hematuria
- Inability to void
- Bilateral corporal body fracture (additional risk factor)
Options for urethral evaluation include retrograde urethrogram or urethroscopy; neither method is superior, and the choice depends on equipment availability and timing 1.
Surgical Management
Timing of Surgery
Immediate surgical repair (within 24 hours) is the standard of care and results in 1, 2:
- Significantly fewer overall complications compared to conservative management (p < 0.000001)
- Lower rates of erectile dysfunction
- Reduced penile curvature
- Decreased painful erection
Delayed surgical repair (>24 hours after injury) should still be performed when patients present late, as contemporary evidence demonstrates adequate postoperative outcomes even with delayed intervention 3, 4.
Surgical Technique
The repair involves 1:
- Surgical approach: Expose the injured corpus cavernosum through either a ventral midline incision or circumcision (degloving) incision
- Tunical repair: Perform with absorbable suture
- Concomitant urethral injury: If identified, repair should be addressed during the same procedure
Common Pitfalls
- Do not delay surgery for imaging in patients with classic clinical presentation, as this increases complication rates 2
- Do not pursue conservative management, as meta-analysis demonstrates significantly worse outcomes including higher rates of erectile dysfunction, curvature, and painful erection 2
- Do not miss urethral injury: Failure to evaluate for urethral involvement when warning signs are present can lead to delayed diagnosis and worse outcomes 1
Outcomes and Follow-up
Expected Complications
Even with optimal early surgical management, long-term complications are not uncommon 5:
- Erectile dysfunction rates vary but are significantly lower with surgical vs. conservative management
- Penile curvature occurs less frequently with immediate repair
- Tertiary referral centers managing larger volumes demonstrate more satisfactory long-term results with fewer complications 5
Postoperative Monitoring
Standardized postoperative follow-up is recommended with routine assessments of 3:
- Erectile function
- Penile curvature
- Urinary symptoms (if urethral injury was present)
The evidence strongly supports immediate surgical intervention as the gold standard, with the AUA guidelines providing Grade B evidence for this recommendation 1. While some studies suggest delayed repair may have acceptable outcomes 3, 4, the preponderance of evidence, including meta-analyses 2, demonstrates superior results with prompt surgical management. The key to optimal outcomes is rapid diagnosis through clinical assessment and swift surgical intervention 2.
