Abstract

Penile and digital systolic pressures were measured with Doppler ultrasonic sthetoscope in 65 normal subjects. This technique is simple, reliable, inexpensive OPD procedure for the detection of penile arterial lesion in patients with impotence. With this study, we concluded that normal men have a PDI ratio above 0.77, and impotent men have a. PDI ratio below 0.63. However, the ratio range from 0.63 to 0.77 is borderline range which is not clearly impotent or normal. Hyperemic stress test is indicated the patient with borderline range. Pelvic steal test can detect vascular pathological condition previously missed by PDI. We indicate this test in the patients with history of intermittent gluteal claudication. We concluded that arteriogenic impotence is easily diagnosed by PDI combined with hyperemic stress test and pelvic steal test, if indicated.
