Fig. 1 Total daily proteinuria at the various time points. It is evident that the value of proteinuria returns to normal range 1 yr after surgery. European Urology 2007 52, 1170-1178DOI: (10.1016/j.eururo.2007.04.024) Copyright © 2007 European Association of Urology Terms and Conditions

Fig. 2 Contribution of operated kidney to the overall renal function at the various time points (radionuclide renal scintigraphy with 99mTc-mercaptoacetyltriglycine). POD=postoperative day.

Fig. 3 Logistic regression model. Full orange curve=evolution of kidney damage over time; it is evident that between 32 and 42min there is a major drop, corresponding to the phase in which parenchymal damage is maximum. The “starting point” of the “critical phase” of warm ischemia is at the 32-min time mark. The interrupted curves correspond to the confidence intervals.
