Penile Fracture

Penile fracture is rupture of the tunica albuginea of an erect penis — a clinical diagnosis (crack, pain, immediate detumescence, swelling) that needs prompt surgical repair, with assessment for urethral injury.

Orientation

The big picture

During erection the tunica albuginea is thin and taut. A sudden bending force (often during intercourse) ruptures it, sometimes with injury to the corpus spongiosum/urethra. The patient reports a cracking/popping sound, immediate pain, rapid loss of erection (detumescence), and swelling/bruising — the 'aubergine/eggplant' deformity from a haematoma contained by Buck's fascia.

Golden rule

Classic penile fracture = prompt surgical repair; always check for a urethral injury before/at surgery. Do not manage it conservatively.

Safety

Red flags

Classic fracture managed conservatively

Worse outcomes — a true penile fracture needs prompt surgical repair.

Concomitant urethral injury — RUG and repair the urethra.

Inability to void after the injury

Suspect urethral involvement before catheterising.

Prompt surgical exploration and repair of the tunical (and any urethral) defect to preserve function and prevent deformity.

Complications

Disease complications
  • Haematoma
  • Urethral injury
  • Penile deformity
Treatment complications
  • Erectile dysfunction, curvature, painful nodules (less likely with prompt repair)
How to prevent
  • Early surgical repair
  • Identify and repair urethral injury
How to manage
  • Treat ED/curvature; manage strictures
Escalation

If treatment fails

Ask first

If curvature or erectile dysfunction develops, ask: is this from delayed repair, an inadequate closure, or an unrecognised urethral injury?

Recall

Memory hooks

Crack + pain + detumescence + eggplant = penile fracture.

It's a clinical diagnosis.

Operate promptly — don't sit on it.

Always check the urethra.

Exam

Board traps

Classic penile fracture → surgical repair, NOT conservative management.

Forgetting to assess for urethral injury.

Catheterising blindly when a urethral injury is suspected.

Clinical cases

Case 1

During intercourse a man hears a crack, feels sudden pain, loses his erection immediately, and develops marked penile swelling and bruising. There is no blood at the meatus and he can void.

What is the diagnosis and the correct management?
