超声在肾结石与肾钙乳症鉴别诊断中的价值及影像特点分析

Values and imaging features analysis of ultrasound in differential diagnosis of renal calculi and disease of kidney calcium latex

目的分析超声鉴别诊断肾结石与肾钙乳症的价值及影像特点。方法选取广州市番禺区沙湾镇社区卫生服务中心2016年3月~2017年3月的126例肾结石患者(A组)和32例肾钙乳症患者(B组)的超声诊断资料进行回顾性分析,计算超声诊断准确率,比较两组超声影像特点差异。结果超声诊断肾结石、肾钙乳症准确率分别为94.44%、90.63%;两组病灶直径比较差异无统计学意义(P>0.05);A组病灶多见于肾盏、肾盏及肾盂,未见于肾实质,B组则多见于肾实质,未见于肾盂,两组差异有统计学意义(P<0.05);A组病灶形态多以团块状为主,无半月形,B组则以半月形为主,无弧形光带,两组差异有统计学意义(P<0.05);A组图像有声影、无声尾、有肾盏积水例数显著高于B组,差异有统计学意义(P<0.05)。结论超声诊断肾结石、肾钙乳症准确率较高,且两者超声影像特点差异明显,对两者鉴别诊断有重要意义。

Objective To analyze the values and imaging features of ultrasound in differential diagnosis of renal calculi and disease of kidney calcium latex.Methods The ultrasonic diagnostic data of 126 cases of patients with renal calculi（the group A） and 32 cases of patients with disease of kidney calcium latex（the group B） from March 2016 to March 2017 in our hospital were analyzed retrospectively.The accuracy of ultrasonic diagnosis was calculated,and the differences of ultrasound imaging features were compared between the two groups.Results The accuracy rates of ultrasound diagnosis of renal calculi and disease of kidney calcium latex were 94.44% and 90.63% respectively,and there was no significant difference in the lesions diameter between the two groups（P〈0.05）.The lesions in the group A were mostly found in renal calyx,calyx and renal pelvis but not in renal parenchyma,and the lesions in the group B were mostly found in the renal parenchyma but not in the renal pelvis（P〈0.05）.The lesions in the group A were mostly clumpy shape without halfmoon shape while the lesions in the group B were mainly half-moom shap without arc-shaped band（P〈0.05）.The number of acoustic shadowing,no ringing effect and having hydrocalycosis in the imaging of the group A was significantly higher than that of the group B,the differences were statistically significant（P〈0.05）.Conclusion The accuracy of ultrasound is high in the diagnosis of renal calculi and disease of kidney calcium latex,and the difference in the ultrasound imageing features of the two is obvious,which is of great significance for the differential diagnosis of the two diseases.
