Comparative study on urine dry chemistry method, urinary sediment analyzer and microscope in the urine examination of urologic neoplasms patients

Abstract

Objective To investigate the value of urine dry chemistry method, urinary sediment analyzer and microscope in the diagnosis of urologic neoplasms. Methods The clinical data of 80 inpatients with urologic neoplasms treated in Nantong tumor hospital from June 2015 to October 2017 were retrospectively analyzed, and all selected cases were confirmed by pathological examination. The urine specimens of all patients were examined by urine dry chemistry method, urinary sediment analyzer and microscope. The detection of white blood cell (WBC) and red blood cell (RBC) in urine of patients were analyzed. Results The positive detection rate of WBC by urine dry chemistry method, urinary sediment analyzer was higher than that by and microscope (P<0.05). The positive detection rate of RBC by urine dry chemistry method, urinary sediment analyzer was higher than that by and microscope (P<0.05). The microscope examination result was taken as the reference standard, the sensitivity and specificity of urine dry chemistry method in the detection of WBC were slightly lower than those of urinary sediment analyzer. The sensitivity and specificity of urine dry chemistry method in the detection of RBC were slightly higher than those of urinary sediment analyzer. The total cost of automatic urine dry chemistry analyzer was less than that of other two inspection instruments, and the utilization rate of instrument was higher. Conclusions The three urine examination methods in the detection of RBC and WBC have some limitations and advantages. When selecting the clinical detection method, the appropriate method should be selected according to the purpose of the test. If necessary, it can be used in combination to reduce the rate of missed detection and improve the accuracy of detection. Key words: Urologic Neoplasms; Urine; Urinalysis; Microscopy
