超声造影在小体积肾肿瘤中的诊断价值

目的探讨超声造影在小体积肾肿瘤中的诊断价值。方法对38例直径小于30 mm的肾脏实质性占位病例进行超声造影,做出良性或恶性病变的诊断,与手术后病理检查和随访结果进行比较。结果 38例患者中35例手术。超声造影检查诊断出恶性肿瘤25例,全部手术,结果 24例为恶性肿瘤,1例为良性肿瘤。另超声造影检查诊断良性肿瘤13例,其中10例手术,8例为良性肿瘤,2例为恶性肿瘤。未手术3例中,2例随访失联,1例随访中。超声造影对小肾脏肿瘤诊断的灵敏度为92.30%,特异度为90.00%,诊断指数182.30%,约登指数82.30%,诊断符合率91.66%。超声诊断与病理诊断结果进行χ2检验分析,P=0.5637。结论超声造影在小体积肾脏肿瘤中的良恶性鉴别有较高的价值。

Diagnostic value of contrast-enhanced ultrasound on small volume renal tumor

Objective To explore the diagnostic values of contrast-enhanced ultrasound(CEUS) on small volume renal tumour.Methods A total of 38 patients with small volume renal solid lesions which were less than 3cm were perfomed with contrast-enhanced ultrasound in the study and make a diagnoses of benign or malignant tumuors,then compare the result with the pathology and follow-up.Results Thirty-five eases underwent surgical treatment.Twenty-five cases malignant tumuors diagnosised by CEU were received surgical treatment,24 cases were malignant and 1 case was binign.Thirteen cases of binign tumuors diagnosised by CEUS,10 cases were received surgical treatment 8 cases were binign and 2 cases were milignant.Three cases were unoperated,2 cases were lost during the follow-up,1 case was in follow-up.CEUS The sensitivity,specificity,diagnosis index,Youden index,diagnosis accuracy rate of CEUS were 92.30％,90.00％,182.30％,82.30％,91.66％ in the diagnosis of small renal tumours,Conclusion CEUS is proved to be a valuable diagnostic method for differentiating small volume renal solid lesions.
