Quantitative analysis of urinary sediment bacteria and application of bacterial culture in diagnosis of urinary tract infection

Zhang Lei;Zhuanghe Central Hospital;  
Objective To explore the quantitative analysis of urinary sediment bacteria and the application of bacterial culture in the diagnosis of urinary tract infection.Methods 284 urine samples were detected by UF-1000 i total automatic urine sediment analyzer and urine bacteria culture,and the results were analyzed and compared.Results Among the 284 urine specimens,60 cases of urine sediment bacteria were positive,the positive rate was 21.13%,the negative 224 cases,the negative rate was 78.87%,the positive rate of urine bacteria culture 57 cases,the positive rate20.07%,the negative 227 cases,the negative rate was 79.93%.There was no significant difference in the difference between the two(P 0.05).With normal bacterial culture as the reference standard,the accuracy rate of quantitative detection of urine sediment bacteria was 94.01%,the sensitivity was 77.92%,the specificity was 100.0%,the detection accuracy of urine bacteria culture was 92.96%,the sensitivity was 74.03%,and the specificity was 100.0%,there was no significant difference between the two groups.Conclusion For the detection of urinary tract infection,urine sediment bacteria count and bacterial culture can be accurately diagnosed clinically.
