Two cases of penile necrosis in diabetics with end-stage renal failure

Distal penile necrosis associated with renal failure is a rare entity; only a few cases have been reported in the literature. Penile necrosis can frequently be a difficult management problem, the etiology of which is infectious, traumatic, or vascular. Physiological abnormalities are usually found in association with this condition, including diabetes, hyperparathyroidism, and peripheral vascular disease. Penile necrosis is a poor prognostic factor associated with high morbidity. We report two cases of this condition, presenting the clinical and pathophysiological background.
