title: Progression to wet gangrene in penile necrosis and calciphylaxis.
abstract: We report a patient who presented with gangrene of the penis due to renal failure and calciphylaxis. In view of his advanced underlying conditions we pursued an expectant approach. Superinfection set in necessitating extensive debridement, demasculinisation and a perineal urethrostomy. Of the 34 reported cases in the literature, 12 (35%) were treated conservatively, 18 (53%) had been treated expectantly with delayed surgery following the development of complications and 4 (12%) underwent early surgery (penectomy). 20 (59%) of the patients subsequently died--8/12 (58%) treated conservatively, 11/18 (61%) treated with expectant surgery and 1/4 (25%) treated with early surgery. Progression to wet gangrene developed in the majority of patients--23/34 patients (68%). Penile gangrene is a symptom of severe systemic disease, where two thirds of affected patients decease within six months of onset of symptoms. Expectant treatment results in superinfection and wet gangrene in the majority of cases who ultimately require extensive surgery and debridement.
