摘　　要：目的比较肾脏肿瘤不同类型患者的基线特征,同时对比核磁共振检查(MRI)、CT以及多普勒超声三种影像学检查方法对于肾脏肿瘤的有无及良恶性诊断能力的一致性。方法回顾性收集解放军总医院第三医学中心2021年2月-2022年1月经过MRI检查的肾脏肿瘤患者118例,部分患者入院时同时进行CT和多普勒超声检查。满足正态的计量资料组间比较采用t检验;不满足正态分布的计量资料组间比较采用Mann-Whitney U秩和检验。计数资料组间比较采用卡方检验或Fisher精确概率法。MRI、CT以及多普勒超声三种影像学检查结果的一致性检验采用Kappa检验。结果118例接受MRI检查的研究对象中,良性肾脏肿瘤患者64例(54.24%),恶性肾脏肿瘤患者117例(99.15%),63例(53.85%)患者同时患有良性和恶性肾脏肿瘤。同时患有良性和恶性肾脏肿瘤的患者中男性患者的比例(49例,77.78%)显著高于仅有良性或者仅有恶性的肾脏肿瘤患者(32例,58.18%),差异有统计学意义(χ^(2)=5.239,P=0.021)。同时患有良性和恶性肾脏肿瘤的患者的中位年龄(59岁;四分位间距:52-65岁)显著高于仅有良性或者仅有恶性的肾脏肿瘤患者(50岁;四分位间距:43-58岁),差异有统计学意义。27名患者同时做了MRI、CT和多普勒超声三种检查,MRI方法检查中患者均为肾脏肿瘤患者,CT检查中诊断为肾脏肿瘤有26人,超声检查中诊断为肾脏肿瘤的有24人,CT检查与MRI检查的一致性比较差(kappa=0.04;95%CI,-0.11~0.48);超声与MRI检查的一致性比较差(kappa=0.11;95%CI,-0.01~0.23);MRI检查中有15例患者诊断为良性肾脏肿瘤,CT检查中有1例患者诊断为良性肾脏肿瘤,两者的一致性较差(kappa=0.09;95%CI,-0.08~0.26),超声检查中2例患者为良性肾脏肿瘤,12例患者良恶性无法判读。结论男性和年龄较大的人更容易患恶性肾脏肿瘤。MRI检查在肾癌患者的诊断及良恶性判断方面优于CT检查和超声检查,�Objective To compare and contrast the baseline characteristics of patients with different types of renal tumors,and also to compare the consistency of three imaging methods:magnetic resonance imaging(MRI),CT,and Doppler ultrasound for the presence or absence of renal tumors and their ability to diagnose benign and malignant properties.Methods One hundred and eighteen patients with renal tumors who underwent MRI examination from February 2021 to January 2022 at the Third Medical Center of the PLA General Hospital were retrospectively collected,and some patients underwent both CT and Doppler ultrasound examination upon admission.The t-test was used for comparison between groups for measures that satisfied normality;the Mann-Whitney U rank sum test was used for comparison between groups for measures that did not satisfy normal distribution.The chi-square test or Fisher's exact probability method was used for comparison between groups of statistical data,and the Kappa test was used to test the consistency of MRI,CT,and Doppler ultrasound findings.Results Among the 118 study subjects who underwent MRI,64 patients(54.24%)had benign renal tumors,117 patients(99.15%)had malignant renal tumors,and 63 patients(53.85%)had both benign and malignant renal tumors.The proportion of male patients with both benign and malignant renal tumors(49 cases,77.78%)was significantly higher than that of patients with only benign or only malignant renal tumors(32 cases,58.18%),and the difference was statistically significant(χ^(2)=5.239,P=0.021).The median age of patients with both benign and malignant renal tumors(59 years;interquartile spacing:52-65 years)was significantly higher than that of patients with benign only or malignant only renal tumors(50 years;interquartile spacing:43-58 years),with a statistically significant difference.27 patients studied had all three types of examinations,MRI,CT and Doppler ultrasound,and all patients were diagnosed with renal tumors in MRI method examination patients,26 were diagnosed with renal tumors
