Value of color Doppler ultrasonography in Diagnosis of erectile dysfunction
Objective To investigate the value of color Doppler ultrasonograpy in the diagnosis of patients with ED who were injected with papaverin plus phentolamine intracavernously. Methods Totally 79 patients with ED were e-valuated by color Doppler ultrasonography. Diagnostic tests were undertaken after an intracavemous injection with papaverin 20 mg plus phentolamine 15 mg. The peak systolic velocity (PSV), end diastolic velocity (EDV), resistive index( RI) of deep penile artery and deep dorsal vein velocity were measured and analyzed. Results There were 23 patients with nonvasculogenic ED(29.1%),35 patients with artenogenic ED(44. 3%),21 patients with venogenic ED(26. 6%). When penis was erected,the PSV,EDV,R1 of nonvasculogenic ED were obviously higher than those of arteriogenic ED(P<0. 05). Deep dorsal vein velocity of venogenic ED was obviously higher than those of nonvasculogenic ED and arteriogenic ED( P<0.05). Conclusions Color Doppler ultrasonography allows accurate location and evaluation of the hemodynamics of the cavernous artery and deep dorsal vein. It is the minimal invasive and accurate method in the diagnosis of ED.
