Abstract:
Objective To investigate the hemodynamic change of venous leakage in venogenic impotence. Methods Thirty-two patients with vasculogenic impotence were evaluated with conventional penile duplex sonography with spectral analysis and color Doppler imaging after intracavernosal injection of PGE1 to induce an erection.The color Doppler appearance of deep dorsal vein of penis,cavernous veins and bulbourethral vein wen observed and the correlativity with resistance index(RI)of cavernous artery were analyzed. Results After five minutes following intracavernous injection,the flow and diameter of the penis vein were continuous increased.The coefficient correlation r between the discharge of deep dorsal vein of penis,cavernous veins and bulbourethral vein with RI of cavernous artery were-0.55,-0.53,-0.24(P＜0.05).Considering the existence of mixed venous leakage,r between the discharge of vein of penis with RI of cavernous artery was-0.88(P＜0.001).Conclusions Higher qualitative ultrasound imaging could demonstrate venous leakage sensitively and assess the location and degree of venous leakage in venogenic impotence initially.
