应用彩色多普勒对４５例正常成人肾内动脉的收缩期加速度和波形进行探讨，为进一步分析各种疾病状态下的肾内动脉血流变化提供对照资料。在双侧肾窦部的上中下段动脉及肾门处的主肾动脉取得８个部位的多普勒频谱信号，测量收缩早期加速度～起始加速度和平均加速度，并把收缩早期波峰（ＥＳＰ）分为五种类型（０～４型）。结果：①正常成人肾内动脉的多普勒波形大多数为１～２型。②肾门比肾窦部的起始加速度和平均加速度高。③起始加速度比平均加速度高。④左右两侧肾脏的相应参数无统计学差异。作者认为：①ＥＳＰ的缺失可能是正常的。②随着动脉的分级，血管顺应性逐渐增加。③双侧肾脏的肾内动脉血流分布是对称的。④对于肾动脉狭窄而言，起始加速度比平均加速度更有价值 The application of color Doppler in 45 cases of normal adult renal artery systolic acceleration and waveform were discussed in order to further analysis of renal disease under various disease conditions to provide blood flow control data. Eight Doppler spectral signals were obtained from the main renal arteries at the upper and middle inferior arteries and the renal hilum of both sides of the renal sinuses. Earlier systolic acceleration ~ initial acceleration and mean acceleration were measured. The early contractile peak (ESP) Divided into five types (0 ~ 4 type). Results: ① Most of the Doppler waveforms of normal adult renal artery were type 1 ~ 2. ② renal door than the initial acceleration of the sinuses and the average acceleration high. ③ initial acceleration than the average acceleration. ④ left and right sides of the corresponding parameters of the kidney no significant difference. The author thinks: ① The loss of ESP may be normal. ② With the classification of arteries, vascular compliance gradually increased. ③ bilateral renal renal artery blood flow distribution is symmetrical. ④ For renal artery stenosis, the initial acceleration is more valuable than the average acceleration
