Factors Predicting Renal Functional Outcome After Partial Nephrectomy

Abstract

Lower preoperative glomerular filtration rate, solitary kidney, older age, gender, tumor size and longer ischemic interval all predicted lower glomerular filtration rate after partial nephrectomy. Therefore, duration of renal ischemia is the strongest modifiable surgical risk factor for decreased renal function after partial nephrectomy, and efforts to limit ischemic time and injury should be pursued in open and laparoscopic partial nephrectomy.
