【摘要】 目的:探讨尿常规联合血清降钙素原检查在尿路感染鉴别诊断中的应用价值。方法:选取我院2017年1月—2018年12月收治的尿路感染患者320例为研究组,另收集同期健康体检人员100例为对照组,纳入对象均进行尿常规及血清降钙素原(PCT)检查,分析比较两组白细胞计数、细菌计数培养结果及PCT检测结果。结果:研究组中不同病理类型患者的白细胞计数均显著高于健康对照组,比较差异有统计学意义(P<0. 05);下尿路感染患者白细胞计数略高于上尿路感染组和慢性肾盂肾炎组,但比较差异无显著性(P>0. 05);健康对照组人群的细菌计数均呈阴性,研究组多数患者细菌培养呈阳性,不同病理类型阳性率均显著高于对照组,比较差异有统计学意义(P<0. 01);研究组中上尿路感染及下尿路感染的阳性率分别为95. 9%和92. 2%,显著高于慢性肾盂肾炎的阳性率(27. 8%),比较差异有统计学意义(P<0. 05);研究组中各病理类型组患者的PCT水平显著高于健康对照组(P<0. 05);研究组中各病理类型组的PCT水平:上尿路感染组>下尿路感染组>慢性肾盂肾炎组,各组之间比较差异有统计学意义(P<0. 05)。结论:尿常规联合PCT检查在尿路感染的诊断中有重要价值,结合细菌计数培养结果及PCT检测结果还可鉴别诊断不同病理类型,有较高的应用价值。更多还原

【Abstract】 Objective: To explore the application value of urine routine combined with procalcitonin test in the differential diagnosis of urinary tract infection. Methods: A total of 320 patients with urinary tract infection who were admitted to our hospital from January2017 to December 2018 were selected as the research group,and 100 healthy medical personnel from the same period were collected as the control group. All the subjects were subject to urine routine and serum procalcitonin( PCT) Examination,analysis and comparison of white blood cell count,bacterial count culture results and PCT test results. Results: The white blood cell count of patients with different pathological types in the study group was significantly higher than that of the healthy control group,and the difference was statistically significant( P<0. 05); the white blood cell count of patients with lower urinary tract infection was slightly higher than that of upper urinary tract infection group and chronic renal pelvis In the nephritis group,there was no significant difference( P>0. 05); the bacterial count of the healthy control group was negative,and most of the patients in the study group were positive for bacterial culture. The positive rate of different pathological types was significantly higher than that of the control group.Statistical significance( P<0. 01); the positive rates of upper urinary tract infection and lower urinary tract infection in the study group were 95. 9% and 92. 2%,respectively,which was significantly higher than the positive rate of chronic pyelonephritis( 27. 8%). Significance( P<0. 05); PCT levels of patients in each pathological group in the study group were significantly higher than those in the healthy control group( P<0. 05); PCT levels in each pathological group in the study group: upper urinary tract infection group> lower urine Road infection group> chronic pyelonephritis group,the difference between the groups is statistically significant( P < 0. 05).Conclusion: Urine routine combined with PCT examination is of great value in the diagnosis of urinary tract infection. Combining bacterial count culture results and PCT test results can also differentiate and diagnose different pathological types,which has a high application value.更多还原
