目的探讨囊内分隔数目及厚度在超声鉴别诊断复杂性肾囊性病灶良恶性中的价值。方法回顾性分析70例(79个病灶)复杂性肾囊性病灶的超声表现,评价所有病灶的分隔数目和厚度,并将诊断结果与“金标准”(病理结果、CT检查、超声随访≥6个月)进行对照,用ROC曲线筛查特异性指标并确定界值。结果 ROC曲线显示分隔厚度对鉴别诊断复杂性肾囊性病灶的良恶性有很高的诊断价值(曲线下面积>0.9);囊内分隔数目对鉴别诊断复杂性肾囊性病灶良恶性有中等诊断价值(曲线下面积>0.7)。囊内分隔数>4条和分隔厚度>1.5mm是鉴别诊断复杂性肾囊性病灶良恶性的最佳界值。结论囊内分隔数目和厚度在鉴别肾复杂性囊肿的良恶性方面有诊断价值,囊肿分隔越多、越厚则恶性的可能性越大。
Objective To investigate the value of the number and thickness of cysts in the differential diagnosis of benign and malignant renal cystic lesions by sonography. Methods A retrospective analysis of 70 cases (79 lesions) of complex renal cystic lesions by ultrasound performance evaluation of all lesions of the number and thickness of the separation, and the diagnostic results with the “gold standard” (pathological results, CT, ultrasound follow-up ≥6 months) were compared, with ROC curve screening specific indicators and determine the cutoff. Results The ROC curve showed that the thickness of the septum had a high diagnostic value in the differential diagnosis of benign and malignant lesions of renal cystic lesions (area under the curve> 0.9); the number of cysts in the differential diagnosis of complex renal cystic lesions with benign and moderate diagnosis Value (area under the curve> 0.7). The number of cysts> 4 and the separation thickness> 1.5mm is the best value for differentiating benign and malignant renal cystic lesions. Conclusion The number and thickness of cysts in the diagnosis of benign and malignant renal complex cysts have diagnostic value, the more cysts separated, the thicker the more likely the malignant.
