A total of 184 patients with suspected impaired venous drainage of cavernous bodies were examined. Dynamic perfusion cavernosography with cavernometry was employed. Venous drainage abnormalities were detected in 158 of 184 examinees. Classification of this drainage abnormalities was elaborated based on the results of these examinations. A drug perfusion method for determining debit deficiency, one of the basic parameters of this classification (together with run-off type), has been developed.
