High-resolution real-time ultrasound in Peyronie's disease.

Sonography is not considered to be a radiation hazard; it is noninvasive and can be widely used for examining external genitalia. We examined six cases of Peyronie's disease of the penis by high-resolution real-time ultrasound. The sonographic findings include a thick echogenic plaque with echogenicity similar to or higher than the tunica albuginea; a calcified plaque in thickened tunica albuginea; and are occasionally associated with calcification in the corpora cavernosa. Sonography may clearly localize the abnormal thickened area of collagen deposition and calcification. Repeated sonography after intracavernosal papaverine injection may further confirm the correlation of the plaque and the abnormally curved erectile penis. Doppler ultrasound may be used for further evaluation of the vascular condition if impotence coexists.
