Cavernosography.

Corpus cavernosography of the penis is a valuable diagnostic technique in Peyronie disease, priapism, trauma, and especially in the evaluation of male impotence. Because it allows visualization of structural abnormalities within the cavernous tissues, it is particularly useful in the differential diagnosis of organic erectile failure. Normal anatomy of the penis and procedures for cavernosography are discussed, and seven cases are presented to illustrate some of the conditions in which cavernosography can provide anatomical and physiological information. Cavernosography was useful in establishing the diagnosis of organic erectile failure caused by structural abnormalities of the corpus cavernosa, and thus aided in the selection of appropriate therapeutic options.

Penile flow index utilizing a Doppler pulse wave analysis to identify penile vascular insufficiency.

A Doppler ultrasound probe was used in 42 men to evaluate penile circulation. Twenty-six patients had confirmation of vascular anatomy by pelvic arteriography. The average penile acceleration (peak velocity over pulse rise time) relative to the radial artery acceleration was expressed as the penile flow index. Eleven potent men had a penile flow index of 3.4 plus or minus 0.4 standard error, while 13 impotent men with vascular disease on arteriography had a penile flow index of 21.7 plus or minus 5 standard error (p less than 0.01). Patients with intermediate penile flow index values had variable degrees of erectile failure. This relatively simple, non-invasive technique identifies a vascular component of impotence, thus aiding in the selection of appropriate management.
