超声造影鉴别诊断不同类型肾脏良恶性肿瘤的临床价值

摘要

Objective To explore the clinical value of contrast-enhanced ultrasound(CEUS) in differential diagnosis of different types of benign or malignant renal tumor.Methods 63 patients with renal tumor were selected and divided according to benign or malignant tumor and different pathological types.Then the results of CEUS of each group were compared and analyzed.Results The main appearance of CEUS of malignant renal tumor was hyper enhancement(69.39％),homogeneous enhancement (65.31％)and fast fading(83.67％),which had great differences compared to benign renal tmnor(P ＜ 0.05).Among the different kinds of malignant renal tumor,the main appearance of CEUS of clear cell carcinoma was hyper enhancement (80.65％),homogeneous enhancement(83.87％)and fast washing out(80.65％),which had great differences compared to papillary carcinoma and chromophobe cell carcinoma(P ＜ 0.05).AT,TTP of clear cell carcinoma were shorter and PI was bigger,which had statistically difference compared to the other 2 types of tumor(P ＜ 0.05).AT and TTP of different stages of patients with clear cell carcinoma had no great differences (P ＞ 0.05).But PI of T3 was obviously higher than other 2 stages with statistically significance (P ＜ 0.05).Conclusion CEUS has positive clinical values in differential diagnosis of different kinds of benign or malignant renal tumor.%目的 探讨超声造影鉴别诊断不同类型肾脏良恶性肿瘤的临床价值.方法 收取肾脏肿瘤患者63例作为研究对象,根据病理结果的肿瘤良恶性以及不同病理类型进行分组,对各组患者超声造影结果进行比较分析.结果 对超声造影结果进行分析,肾脏恶性肿瘤主要以高增强(69.39％)、均匀增强(65.31％)以及快消退(83.67％)为主要表现,与肾脏良性肿瘤相较,有统计学差异(P＜0.05).在不同病理类型肾脏恶性肿瘤中,透明细胞癌以高增强(80.65％)、均匀增强(83.87％)以及快进快退(80.65％)为主要表现,与乳头状细胞癌及嫌色细胞癌相较,有统计学差异(P＜0.05).透明细胞癌始增时间(AT)、达峰时间(TTP)均较短,达峰强度(H)较大,较乳头状细胞癌及嫌色细胞癌相比,有统计学差异(P＜0.05).不同分期肾脏透明细胞癌患者AT及TTP差异无统计学意义.T3期患者PI明显高于其他期患者,差异有统计学意义(P＜0.05).结论 超声造影对肾脏肿瘤良恶性及病理分型诊断均有一定的临床价值.
