目的研究肾脏实质性肿瘤通过C T三维重建测量的体积与术后立即测量肿瘤病理体积之间的差异.方法分析2014年2~12月在山西医科大学第一医院行肾脏肿瘤手术且临床病理资料完整的92例患者的资料 ,采用配对 t检验比较平均C T三维重建测量的体积与病理体积之间的差异.结果 92例患者的平均C T三维重建体积为(167 .42 ± 105 .50 )m L ,平均病理体积为(96 .21 ± 81 .37 )m L ,二者之间差异有统计学意义( t=20 .269 ,P<0 .001 ).92例患者中 ,C T 三维重建体积均较病理体积大.以病理类型分层分析的结果显示 ,透明细胞癌、嫌色细胞癌以及其他类型癌的肿瘤的影像学体积均较病理体积大 ,二者的差异均有统计学意义(均 P<0 .05).以手术类型分层分析的结果显示 ,无论是根治性肾切除手术还是保留肾单位手术 ,CT三维重建体积与病理体积的差异均有统计学意义(P均<0 .05).统计结果显示CT 三维重建测量的体积与术后立即测量肿瘤病理体积两种检测方法呈高度正相关 ,r=0 .968.结论肾脏实质性肿瘤通过C T三维重建测量的体积与术后立即测量体积之间差异有统计学意义 ,这可能会对临床医师的术前临床决策及预后判断产生一定影响.

Objective To investigate the difference between renal tumor volume measured with preoperative computed tomography (CT) three-dimensional reconstruction and the volume measured after surgery in Chinese patients .Methods Clinical data of 92 patients with renal tumors treated in the First Hospital of Shanxi Medical University during Feb .2014 and Dec .2014 were retrospectively analyzed .Paired t-test was used to compare the two types of volumes .Results The mean CT three-dimensional reconstruction volume of tumors was (167 .42 ± 105 .50 )mL and the mean pathological mean volume was (96.21 ± 81 .37)mL ,with statistical difference between them (t=20 .269 ,P<0 .001) .When subjects were categorized accord-ing to histologic and surgical type ,statistically significant difference was observed between the two types of volumes ( P<0.05) ,and the correlation coefficient was 0 .968 .Conclusion There is a statistically significant difference between the mean computed CT three-dimensional reconstruction volume and the mean pathological tumor volume ,which may have implications on preoperative decision and prognostic prediction .
