Renal Cancer Surgery in Patients without Preexisting Chronic Kidney Disease—Is There a Survival Benefit for Partial Nephrectomy?

PURPOSE: or greater. MATERIALS AND METHODS: or greater. RESULTS: 10-year nonrenal cancer related mortality was still substantially improved after partial nephrectomy (10.6% vs 16.3%, p <0.001). In this population age, gender and partial vs radical nephrectomy were associated with nonrenal cancer related mortality on multivariable analysis (all p ≤0.001). In contrast, the increased new baseline glomerular filtration rate, as seen for partial nephrectomy, was not associated with reduced nonrenal cancer related mortality. CONCLUSIONS: or greater partial nephrectomy was associated with improved survival. However, the functional dividend, namely the increased new baseline rate, failed to correlate, suggesting that selection bias may also impact outcomes.
