A study of possibilities of different ultrasound (US) methods in the estimation of renal blood flow was made in 35 patients with angiographically documented renal artery stenosis. The validity of data obtained with US B-scanning and Doppler technique was estimated by comparison with direct artery diameter and US blood flow measurements made intraoperatively during reconstructive renal artery surgery in 25 patients. It was shown that US Doppler spectral characteristics obtained noninvasively before surgery and intraoperatively were identical. Posterior-lateral approach is optimal for Doppler examination. Differences between Doppler spectrum in the presence and absence of renal artery stenosis (RAS) were revealed. Among the RAS sensitive spectrum waveform characteristics were end-diastolic to peak systolic velocity ratios, pulsatility index, resistance parameter.
对35例经血管造影证实有肾动脉狭窄的患者进行了不同超声（US）方法评估肾血流可能性的研究。通过与25例接受肾动脉重建手术患者术中直接测量的动脉直径和超声血流测量结果进行比较，评估了B超扫描和多普勒技术所获数据的有效性。结果显示，术前和术中通过无创获得的超声多普勒频谱特征是相同的。后侧入路是多普勒检查的最佳途径。揭示了存在和不存在肾动脉狭窄（RAS）时多普勒频谱之间的差异。在RAS敏感的频谱波形特征中，有舒张末期与收缩期峰值速度比、搏动指数、阻力参数。
