Unilateral renal blood flow was evaluated in-situ in 13 dogs by cineangiodensitometry and microsphere distribution studies before and after intermittent balloon occlusion with and without hypothermic perfusion of one kidney. The contralateral kidney served as control. No significant difference in renal blood flow and vascular resistance was noted before, and 5, 30 and 60 minutes after unilateral intra-arterial manipulation. Compartmental flow distribution studies in 5 dogs revealed no evidence of alteration of intra-renal haemodynamics. In a clinical pilot study, unilateral renal blood flow measured by cineangiodensitometry showed no change of clinical significance 5 and 60 minutes after intraluminal balloon occlusion of the renal artery for 60 seconds.
通过电影血管密度测定法和微球分布研究，在13只犬身上原位评估了一侧肾脏间歇性球囊闭塞前后（有或无一侧肾脏低温灌注）的单侧肾血流量。对侧肾脏作为对照。在单侧动脉操作前、操作后5分钟、30分钟和60分钟，未发现肾血流量和血管阻力有显著差异。对5只犬进行的分区血流分布研究未发现肾内血流动力学改变的证据。在一项临床初步研究中，通过电影血管密度测定法测量的单侧肾血流量在肾动脉腔内球囊闭塞60秒后5分钟和60分钟时，未显示出具有临床意义的变化。
