Peyronie's disease and erectile failure.

A total of 20 patients with Peyronie's disease, including 15 with erectile failure and 5 with normal potency, underwent evaluation with dynamic xenon washout and infusion cavernosography. Abnormal drainage from the cavernous body was found in 13 of the 15 patients with erectile failure and in none of the 5 potent patients (p less than 0.01), indicating that this condition seems to be the underlying pathological mechanism leading to erectile impotence in patients with Peyronie's disease.
