[The value of corpus cavernosum sonography following administration of vasoactive substances in the diagnosis of patients with erectile impotence].

In 70 Patients with erectile dysfunction, ultrasound examination of both corpora cavernosa after intracavernous injection of papaverine was done using B-scan, Duplex scan and Doppler color. B-scan can detect morphological disease in a penis profundis, the higher degrees of cavernous muscle myopathia, and disease of the tunica albuginea. For the analysis of pulse curve and the measurement of blood-flow velocity, the Duplex scan is necessary. Doppler color imaging enables ultra sonographic examination of a dorsalis and a penis profundis and can detect intracavernous vascular pathology. The results show that ultrasonography is an important diagnostic tool in patients with erectile dysfunction. A differentiated therapeutic strategy can be based on this examination, especially when revascularization procedures are being discussed. Additionally, better follow-up of patients under self-injection therapy is possible.
