Results
Warm ischemic time was significantly shorter in the AV group than the AO group (26.3 vs. 30.7 min, respectively, p = 0.007). There were no differences in the estimated glomerular filtration rates or ERPF of the operated kidney between groups preoperatively or 1 week or 6 months postoperatively. The decrease in regional 99mTc-MAG3 uptake of the operated kidney at 1 week was correlated with warm ischemic time in both groups, being stronger in the AV group (p < 0.001) than in the AO group (p = 0.027). This decrease was significantly less in the AO group when the ischemic time was less than 25 min (88.1% vs 102.5%, p = 0.001).
