Comparison of Cold and Warm Ischemia During Partial Nephrectomy in 660 Solitary Kidneys Reveals Predominant Role of Nonmodifiable Factors in Determining Ultimate Renal Function

This nonrandomized, comparative study suggests that within the relatively strict parameters of conventional practice, ie predominantly short ischemic intervals and liberal use of hypothermia, ischemia time was not an independent predictor of ultimate renal function after partial nephrectomy. Long-term renal function after partial nephrectomy is determined primarily by the quantity and quality of renal parenchyma preserved, although type and duration of ischemia remain the most important modifiable factors, and warrant further study.
