Radiographic variables changes at postoperative 12 months after partial nephrectomy according to ischemic type. Parenchymal enhancement ratio was defined as the ratio of the parenchyma enhancement (HU) to the aorta enhancement (HU).

	Cold ischemia (n = 53), median (IQR)	Zero or selective ischemia (n = 51), median (IQR)	p value
Parenchymal thickness
Preoperative (mm)	20.10 (16.10–22.50)	19.45 (16.46–21.76)	0.361
Postoperative (mm)	19.45 (15.63–21.43)	19.06 (15.68–20.86)	0.199
Difference (mm)	0.41 (0.05–1.16)	0.30 (0.01–0.71)	0.236
Percent change (%)	2.71 (0.50–5.64)	1.93 (0.07–3.40)	0.070

	Cold ischemia (n = 53), median (IQR)	Zero or selective ischemia (n = 51), median (IQR)	p value
Parenchymal enhancement ratio
Preoperative	69.34 (61.61–74.89)	69.09 (36.28–74.53)	0.872
Postoperative	66.28 (60.74–71.92)	66.78 (61.71–71.76)	0.501
Difference	3.09 (0.16—7.66)	1.57 (3.67–6.33)	0.579
Percent change (%)	3.57 (0.23–10.37)	2.16 (5.55–8.49)	0.557
