description

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.
