Renal failure is an important cause of postoperative morbidity and mortality in infrarenal aortic reconstruction. Several mechanisms for this postoperative renal dysfunction have been suggested. However, biochemical testing of renal function is insensitive since it shows only gross renal changes. ⋯ Six months later GFR decreased, the mean decrease was 9 ml/min. (P = 0.007 Wilcoxon rank). Some of our patients showed an increased GFR, a phenomenon that was recognised recently. None of the factors studied, except division of the left renal vein, had any effect on the changes in the GFR in the immediate postoperative period or 6 months later.
