The aim of this study was to prospectively evaluate the effect of the use of the external iliac artery on erectile function, hormone profiles and penile blood flow by evaluating changes in penile colour Doppler ultrasound parameters in a consecutive series of 22 recipients before and after end-to-side external lilac artery transplantation. The mean International Index of Erectile Function-Erectile Function （IIEF-EF） domain score decreased significantly 3 months after transplant （18.09±6.33 vs. 22.50±7.09, P=O.01）. The reduction in peak systolic velocity （PSV） was significant for the cavernous artery homolateral to the side of transplant （42.60±18.77 vs. 52.01±19.91, P=0.01）. The mean postoperative end diastolic velocity （EDV） did not differ significantly from the preoperative value （P=0.74）. No statistical differences were found in the serum levels of testosterone or prolactin. Kidney grafts anastomosed at the external lilac artery produced significant （P=0.01） reductions in arterial inflow at the homolateral cavernosal artery that remained above the normal threshold. Whether these haemodynamic changes can explain the worsening of postoperative erectile function remains to be proven.展开更多
