Definition / general
  • Condition in which the foreskin cannot be easily advanced over glans and becomes trapped between coronal sulcus and glans corona
  • May be secondary to forceful retraction of phimotic foreskin over glans, causing marked swelling which blocks replacement of foreskin

Causes:
  • Phimosis: leads to a circular scar, which can form a tourniquet when foreskin is retracted, preventing proper venous and lymphatic drainage
  • Iatrogenic: medical staff fails to reduce foreskin after urethral catheterization or genital exam
  • Poor urogenital hygiene, chronic balanoposthitis or genital piercing (West J Emerg Med 2009;10:281)
Clinical features
  • Painful, associated with urinary retention and constriction
  • Edema due to obstruction rarely causes penile ischemia and infarction
  • One of the few male GU emergencies (others are priapism, testicular torsion, Fournier gangrene)
