Volumetric measurement of compensatory hypertrophy in the contralateral normal kidney by the tumor growth

摘要: We evaluated the association between tumor size and preoperative volumetric kidney parameters measured with CT in patients renal cell carcinoma (RCC). prospectively identified 1118 who underwent radical or partial nephrectomy for RCC 2011 2014. Contrast-enhanced was performed within three months before surgery. Kidney volume using a tissue segmentation tool program from images. classified into groups depending on (A: ≤4 cm, B: 4–7 cm, C: >7 cm). The were compared multivariable linear regression used to analyze potential factors associated compensatory hypertrophy of contralateral normal Patients group C had significantly larger than A B 170.0 mL, 171.7 mL, 187.2 mL, p   0.05). However, tumor-side real smaller that 168.8 mL, 164.9 mL, 150.9 mL, 7 cm), negatively older age (p  7 cm, coefficient = 30.2). Tumor (>7 cm) is strongest factor
