Results The average hemodynamics data of the diabetic ED patients vs that of the psy-chogenic ED patients in terms of peak flow velocity (PFV):20. 06±7.15cm/s vs 35. 82±9. 41cm/s, end diastolic velocity (EDV) : 8. 82±0. 35cm/s vs 5. 51±0. 42cm/s,artery diameter (Ad) : 0. 78±0. 25cm vs 1. 01±0. 42cm, vein diameter ( Vd) : 1.05±0. 32mm vs 1.21±0. 45mm, resistance index(RI) : 0. 72±0. 28 vs 0. 98±0. 31,mean velocity of artery (MV):6. 71±0. 27cm/s vs 10. 31±3. 32cm/s, dorsal deep vein flow(DDVF) : 28. 81±6. 32cm/ s vs 25. 74±0. 58cm/s. Stasticstical differences existed in PFV, Ad,RI and MV(P <0. 01). The arterial wall is thick and rigid in diabetic ED patients. Conclusion Atheroscleorsis and veno-occlusive dysfunction of the corpus cavernosum are essential to the development of diabetic ED.展开更多
