摘要
目的分析尿沉渣检查在肾脏疾病临床诊断中的应用价值。方法选取2016年2月-2019年4月184例医院收治的肾脏疾病患者,随机分为观察组(92例)与对照组(92例)。对照组采用普通显微镜进行尿沉渣检查,观察组采用特殊显微镜进行尿沉渣检查。观察两组患者在红细胞、白细胞、管型以及结晶等方面的阳性率,同时比较两种检查方法在肾脏疾病筛查中的敏感度、特异性与准确性。结果观察组与对照组的红细胞阳性率为97.8%和95.7%、白细胞阳性率为96.7%和92.4%、管型阳性率为81.5%和77.2%、结晶阳性率为81.5%和68.5%,两组间的差异无统计学意义;特殊显微镜检查与普通显微镜检查的诊断敏感性为97.8%和96.7%、诊断特异性为91.3%和67.4%、诊断准确率为91.3%和91.3%,两种检查方法在敏感性和准确率方面的差异无统计学意义,但特殊显微镜检查在诊断特异性方面明显高于普通显微镜检查(P<0.05)。结论尿沉渣检查在肾脏疾病诊断敏感性与准确性方面较高,但特殊显微镜尿沉渣检查的诊断特异性明显高于普通显微镜尿沉渣检查。
Objective To analyze the value of urine sediment examination in clinical diagnosis of renal diseases. Methods 184 patients with renal diseases treated in hospital from February 2016 to April 2019 were randomly divided into observation group(n=92) and control group(n=92). The control group was examined by ordinary microscope, and the observation group was examined by special microscope. The positive rates of red blood cells, white blood cells, tube type and crystallization in the two groups were observed, and the sensitivity, specificity and accuracy of the two methods in renal disease screening were compared. Results The positive rate of red blood cells in the observation group and the control group was 97.8. % and 95.7%, leukocyte positive rate 96.7% and 92.4%, tubular type positive rate 81.5% and 77.2%, crystallization positive rate 81.5% and 68.5%. There was no significant difference between the two groups. The diagnostic sensitivity of special microscope was 97.8% and 96.7%, the diagnostic specificity was 91.3% and 67.4%, and the diagnostic accuracy was 91.3% and 91.3%. There was no significant difference in sensitivity and accuracy between the two methods, but the diagnostic specificity of special microscope was significantly higher than that of ordinary microscope. P<0.05). Conclusion urinary sediment examination has high sensitivity and accuracy in the diagnosis of renal diseases, but the diagnostic specificity of special microscope urine sediment examination is significantly higher than that of ordinary microscope urine sediment examination, which is worth popularizing in clinical screening of renal diseases.
