Paraphimosis

Background

• Foreskin trapped behind glans
• Urologic emergency
  • May result in glans necrosis if not reduced due to venous engorgement causing arterial compromise

Evaluation

• Pain, erythema, swelling distal to constricting ring of foreskin

Differential Diagnosis

Non-Traumatic penile diagnoses

• Phimosis
• Balanoposthitis
• Paraphimosis
• Priapism
• STDs

Management

• Reduction
  • Perform as soon as possible
  • Consider penile block, local anesthetic cream (EMLA) or procedural sedation
  • Use bag of ice (3min intervals) or manual compression before attempting reduction
    • Wrap glans with 2x2-in. elastic bandage for 5min
  • Use thumbs to push the glans into the foreskin while index fingers pull foreskin back into normal position
• If fails obtain emergent urology consult and/or perform the following:
  • Use 22-25ga needle to make multiple punctures (3-5mm deep) in foreskin (expresses glans edema fluid) and then perform compression
  • Inject hyaluronidase into the swollen foreskin to decrease edema
  • Can also use several evenly spaced, babcock (noncrushing) clamps around foreskin, followed by gentle traction to pull phimotic ring over the glans
  • Dorsal Slit indicated if evidence of impaired perfusion and urologist unavailable

Disposition

• Refer all cases to urology to determine need for circumcision
