To evaluate the influence of various parameters on peak systolic velocity in the transplanted renal artery and to define the normal range of peak systolic velocity.
Color Doppler ultrasonographic (US) findings in 105 patients were reviewed. There were no clinical or biologic findings suggestive of a stenosis in the transplanted renal artery in these patients. The peak systolic velocity in the transplanted renal and external iliac arteries and the renal resistive index were measured.
A large range of peak systolic velocities was noted in the transplanted renal artery. Peak systolic velocity in the renal artery was statistically significantly correlated with that in the external iliac artery when there was no pronounced vessel curvature. There was no relationship between peak systolic velocity and resistive index or time between transplantation and US. High peak systolic velocity was associated with a pronounced vessel curvature.
The normal range of peak systolic velocity in the transplanted renal artery has considerable variability. Because of the strong correlation, the ratio of velocity in the renal artery to that in the external iliac artery may be useful in detection of stenosis.
评估各种参数对移植肾动脉峰值收缩速度的影响，并确定峰值收缩速度的正常范围。
回顾了105例患者的彩色多普勒超声（US）检查结果。这些患者没有临床或生物学检查结果提示移植肾动脉狭窄。测量了移植肾动脉和髂外动脉的峰值收缩速度以及肾阻力指数。
移植肾动脉的峰值收缩速度范围很广。当没有明显的血管弯曲时，肾动脉的峰值收缩速度与髂外动脉的峰值收缩速度在统计学上有显著相关性。峰值收缩速度与阻力指数或移植与超声检查之间的时间无关。高峰值收缩速度与明显的血管弯曲有关。
移植肾动脉峰值收缩速度的正常范围有很大的变异性。由于存在强相关性，肾动脉与髂外动脉的速度比值可能有助于检测狭窄。
