Abstract
Penile indurations were found at follow-up examination in six of 120 patients with erectile dysfunction who practice intracavernosal self-injection of papaverine-phentolamine. In four of these six, cavernosal calcifications were demonstrated by means of ultrasound (US) and radiography. Most of the calcifications were close to the site of injection, but some were more distant. Cavernosal calcifications must be considered a possible complication of self-injection of papaverine-phentolamine. Baseline US and radiographic studies of the penis are advisable before starting treatment.
