Color Doppler ultrasonography in the test of penile hemodynamic in patients with erectile dysfunction

Objectives: To evaluate the value of color Doppler ultrasonogrphy in the tests of penile hemodynamic(PHD) in patients with erectile dysfunction,and to explore some influencing factors on the accurate diagnosis with the tests.Methods: A total of 179 cases of ED patients were treated with drug-induced erectile of penis,and then were evaluated with CDU tests in terms of cavernosal artery blood flow index,including peak systolic velocity(PSV),end diastolic velocity(EDV),and resistance index(RI).Result: CDU tests indicated 123 patients(68.7%) with non vasculogenic ED,twenty-one patients(11.7%) with arteriogenic ED,and thirty-five patients(19.6) with venous ED.Conclusion: Color Doppler ultrasonogrphy provides a reliable diagnosis for PHD in patients with erectile dysfunction.Penis angiography and cavernosum angiography are needed to determine the specific lesion and the corresponding surgery plan.
