Palliative Nerve Block for Penile Calciphylaxis: A Case Report on Ultrasound-Guided Phenol Neurolysis.

A 78-year-old man with uncontrolled diabetes, heart failure, and hemodialysis-dependent end-stage renal disease presented with intractable penile pain secondary to calciphylaxis and necrosis of his glans penis. Given pain refractory to pharmacologic management and refusal of surgery, treatment entailed an ultrasound-guided dorsal penile nerve block with 5 mL of aqueous 4% phenol bilaterally. The patient reported immediate relief and died pain-free 3 months later.
