Penile Fracture
Penile fracture is a urological emergency defined by a traumatic tear of the tunica albuginea — the dense fibrous sheath encasing the corpora cavernosa — resulting from excessive bending force applied to an erect penis. Despite the dramatic presentation, the diagnosis is primarily clinical, and prompt surgical repair within days of injury is associated with superior outcomes compared to delayed or conservative management. Approximately 15% of penile fractures are associated with a concomitant urethral injury, which must be identified and repaired concurrently.[1] This page is based on the ACS Best Practices Guidelines for Management of Genitourinary Injuries (August 2025).[2]
Mechanism and Anatomy
Penile fracture occurs when the erect penis bends excessively during sexual activity or is forcibly deflected against the perineum, partner's body, or bedding. The classic injury mechanism involves aggressive manual manipulation or atypical coital positioning. At the moment of injury, intracavernosal pressure within the corpora cavernosa can exceed 1,500 mmHg — sufficient to rupture the tunica albuginea when applied perpendicular to its fibers.
The tunica albuginea is thinnest on the ventral and lateral surfaces of the penile shaft, distal to the suspensory ligament — the most frequent sites of rupture.[2] Fractures may be unilateral or bilateral, involving one or both corpora cavernosa. The posterior bulbar urethra, which lies immediately ventral to the bulbocavernosus musculature in close proximity to the corpora, is at risk for concomitant injury when force is applied to the penoscrotal junction.
Clinical Presentation and Diagnosis
The diagnosis of penile fracture is made by history and physical examination in the majority of cases — imaging is not required when the clinical picture is unambiguous.[2]
Classic triad:
- Audible popping or cracking sound at the time of injury
- Immediate detumescence with rapid deflation of the erection
- Severe penile pain, ecchymosis, and swelling
Physical examination findings:
- Penile ecchymosis and hematoma (may involve the scrotum and perineum if Buck's fascia is disrupted)
- Penile deviation or deformity ("eggplant" or "rolled sausage" deformity depending on hematoma extent)
- Palpable defect in the tunica albuginea (present in some cases)
:::note When Imaging Is Indicated For patients with indeterminate history or physical examination — atypical mechanism, delayed presentation, obesity preventing palpation, or complex anatomy — penile ultrasound or MRI may be used to evaluate for fracture. Both modalities have excellent sensitivity and specificity. The choice is based on clinician index of suspicion, availability, and institutional capability.[2] :::
Associated Urethral Injury
Approximately 15% of penile fractures have an associated urethral injury.[1] Evaluate for urethral involvement when any of the following are present:[2]
- Blood at the urethral meatus
- Gross hematuria
- Difficulty urinating, weak urinary stream, or acute urinary retention
- Inability to pass a urethral catheter
When urethral injury is suspected, perform RUG or cystourethroscopy before or at the time of surgical exploration. The urethra may be involved in up to 50% of penile penetrating (ballistic) injuries as well.
Do not attempt urethral catheterization in a patient with a known or highly suspected penile fracture until urethral injury has been excluded — a blind catheter pass through an injured urethra can create a false passage or extend the injury.
Operative Management
Timing
Perform surgical exploration within 7 days of injury for patients with signs, symptoms, or imaging consistent with penile fracture.[2] Earlier intervention — ideally near the time of presentation — is associated with:[3]
- Reduced postoperative pain
- Faster convalescence
- Lower risk of penile curvature (Peyronie's-like deformity)
- Higher rates of preserved erectile function
Conservative (non-operative) management is associated with higher complication rates including abscess, penile fibrosis, Peyronie's disease-like plaques, and chronic erectile dysfunction. Surgical repair is the standard of care.
For patients presenting to a lower-level trauma center without urology coverage, consider early transfer to a center with urology expertise once the patient is stabilized.
Surgical Approach
The incision approach is based on the suspected location of injury:[2]
| Injury Location | Preferred Incision |
|---|---|
| Distal or unknown | Circumcising degloving incision (allows complete bilateral corpus exposure) |
| Proximal or ventral penoscrotal | Ventral midline penoscrotal incision |
Technique:
- Degloving: Mobilize penile skin to allow full exposure of the bilateral corpora cavernosa and the region of suspected tunica albuginea disruption
- Artificial erection (optional): Inject saline (with or without dilute methylene blue) directly into the corporal body to identify the exact location and extent of the tunica tear when the fracture site is not immediately apparent
- Tunica repair: Close the tunica albuginea disruption with absorbable sutures (typically 2-0 polyglycolic acid or PDS); horizontal mattress or interrupted sutures depending on tear configuration; ensure a watertight closure
- Concomitant urethral repair: When urethral injury is identified at the time of tunica repair, perform urethroplasty over a urethral catheter using a tension-free, watertight closure with absorbable suture; a Foley catheter is left in place regardless of whether SPT is also placed
- Drain: Closed-suction drain placement is at surgeon discretion; typically not required for isolated fracture repair
Post-Operative Care
- Urethral catheter for 7–14 days if urethral repair was performed
- Sexual abstinence for 4–6 weeks minimum
- Follow-up for assessment of penile curvature, erectile function, and voiding (if urethral repair performed)
Outcomes and Complications
| Outcome | Notes |
|---|---|
| Erectile dysfunction | Rare after prompt repair; higher with delayed repair or conservative management |
| Penile curvature | More common with delayed repair; may require Nesbit procedure or grafting if symptomatic |
| Urethral stricture | Risk increases with concurrent urethral injury; follow-up voiding cystourethrogram or uroflowmetry recommended at 3 months if urethroplasty performed |
| Wound complications | Uncommon; hematoma and wound dehiscence are the most frequent early complications |
Penetrating Penile Injury
Penile penetrating injuries are most commonly caused by gunshot wounds and are frequently associated with abdominal, pelvic, and lower extremity injuries.[2] The urethra is involved in up to 50% of penile ballistic injuries.
Management:
- Immediate surgical exploration with irrigation, conservative debridement of nonviable tissue, removal of foreign bodies, and repair of all involved structures
- Corporal body involvement: repair as for penile fracture (absorbable suture closure of corporotomy or tunica defect)
- Urethral involvement identified at exploration: debridement and primary urethroplasty over a urethral catheter with tension-free, watertight closure
- For patients at lower-level trauma centers: transfer to a center with urology expertise for definitive penile injury management once stabilized
