Postoperative Serum Creatinine, % Change in Postoperative Serum Creatinine, and Estimated Glomerular Filtration Rate (Ablation versus Partial Nephrectomy)

	Ablation	Partial nephrectomy	P value
Time	Estimated GFR (mL/min/1.73 m2)	Estimated GFR (mL/min/1.73 m2)	–
Preoperative	59	59	0.91
3 months	52	53	0.76
12 months	51	52	0.78

Calculated using Mean Modification of Diet in Renal Disease equation.

GFR=glomerular filtration rate.
