Value of Urine Dry Chemical Method Combined with Urine Sediment Method in Routine Urine Test in the Diagnosis of Urinary Tract Infection
Objective To investigate the diagnostic value of urine dry chemical method combined with urine sediment method in urine routine test of suspected urinary tract infection.Methods The clinical data of 75 patients with sus-pected urinary tract infection treated in Liaocheng Maternal and Child Health Hospital from April 2020 to September 2023 were retrospectively selected.All of them were tested by urine dry chemical method and urine sediment method.Using the results of urine bacterial culture as the diagnostic gold standard,the diagnostic efficacy values of urine dry chemical method and urine sediment method were compared.Results The gold standard showed that 71 cases were positive and 4 cases were negative among 75 suspected patients with urinary tract infection.Urinary dry chemical method detected 62 positive cases and 13 negative cases,with sensitivity,specificity,and accuracy of 84.50%,50.00%,and 82.67%,respectively.Urine sediment method detected 65 positive cases and 10 negative cases,with sen-sitivity,specificity,and accuracy of 90.14%,75.00%,and 89.33%,respectively.The combination of urine dry chemi-cal method and urine sediment method detected 73 positive cases and 2 negative cases,with sensitivity,specificity,and accuracy of 98.59%,25.00%,and 94.67%,respectively.Compared with the diagnosis results of single method,the sensitivity,accuracy of urine dry chemical method combined with urine sediment method were higher,but the specificity was lower,and the differences were statistically significant(all P<0.05).Conclusion In patients with sus-pected urinary system infection,urine dry chemical method combined with urine sediment method for urine routine test can better understand the condition of patients,and urine routine can also be used as an important indicator to judge urinary system infection,so as to provide a more reliable basis for future treatment.
