The value of duplex scanning in the assessment of impotence was evaluated in 146 impotent men. Scanning was by means of a Diasonics DRF 400 and penile artery measurements were taken before and after the intracorporeal injection of papaverine hydrochloride. The penile/brachial index was measured in 82 patients and its predictive value compared with the results of duplex scanning and papaverine-induced erection. On scanning evidence of good arterial inflow but poor erections, indirect evidence of venous leakage was assumed. The results showed that the deep artery responses best characterised the erectile response, with the dorsal artery being less helpful. All 37 patients with full erections following papaverine exhibited bilateral deep artery peak velocities of greater than or equal to 25 cm/s. Of the remaining 109 sub-optimal responders, 17 also has this finding; all had undergone dynamic cavernosography, with 16 exhibiting venous leakage. The penile/brachial index was found to classify 13 patients incorrectly. A critical value of deep artery response to attain erection is postulated, enabling more logical use of cavernosography. The penile/brachial index was shown to be suspect and it was concluded that duplex scanning is a useful, non-invasive method in the assessment of impotence.
