“…Urinary sediment examination is a clinically important stage of urinalysis, especially when the sample presents alterations in the physical and chemical phases. Thus, all the compounds in the urine sediment should be evaluated adequately [6].…”

A comparative study on the performances of 77 elektronika urised 2-LabUmat2 and Dirui FUS200 -H800 urine analyzersObjectives: This study aims to compare the analytical performance of the 77Elektronika brand LabUmat2-Urised2 model integrated urine analyzer and Dirui brand FUS200-H800 model integrated urine analyzer. Methods: Urine samples of 139 patients randomly selected from male and female patients of all age groups who were admitted to Ufuk University Faculty of Medicine, Dr. Ridvan Ege Hospital between 24.02.2020-28.02.2020 were analyzed on both devices. Results: The results of the samples whose WBC (white blood cell), RBC (red blood cell) and Squamous epithelial were measured using two different methods in microscopic analyzers were perfectly compatible in the same range and with three parameters (Gamma values 0.916; 0.770; 0.961, respectively). For the samples where crystal and cylinder tests were carried out in microscopic analyzers, Cappa values were 0.486 and 0.495, respectively. As the result of Passing-Bablok Regression analysis used for the method comparison of microscopic analyzers, Cusum test results were p<0.01, p=0.01 and p=0.65, respectively for the linearity in the measurement of WBC, RBC and Squamous epithelial. According to the Bland-Altman Compatibility Chart prepared to determine the difference between methods, the difference between the results of the measurements of WBC, RBC and Squamous epithelial in both devices were -29.3±1.

The technique of supernatant removal in urine sediment examination using the Shih-Yung method can be done by aspirating and decanting. The aspirated technique is the recommended technique. The Central Laboratory Installation of Dr. M. Djamil Hospital, Padang used decanted supernatant removal technique. The variety of preanalytical procedures affect the results of urine sediment examination. This study aimed to analyze the agreement of erythrocyte, leukocyte, and non-hyaline cast sediment examination results using the Shih-Yung method in aspirated and decanted supernatant removal technique. This study was an analytical observational study with a cross-sectional design of 37 urine specimens that met the inclusion and exclusion criteria at the Central Laboratory Installation of Dr. M. Djamil Hospital, Padang from July to September 2020. Examination of erythrocyte, leukocyte, and non-hyaline cast sediment using Shih-Yung method with aspirated and decanted supernatant removal technique. Numeric data were analyzed using the Mann-Whitney U test and Cohen's Kappa test for the degree of agreement, p-value < 0.05 was considered significant. The agreement test results for erythrocyte, leukocyte, and non-hyaline cast sediment in aspirated and decanted supernatant removal technique were (Kappa=0.88, p < 0.05), (Kappa=0.83, p < 0.05), and (Kappa=0.86, p < 0.05), respectively. The degree of agreement test results for erythrocyte, leukocyte, and non-hyaline cast sediment using the Shih-Yung method in aspirated and decanted supernatant removal technique were almost perfect and statistically significant. The technique for supernatant removal in urine sediment examination using the Shih-Yung method can be done by decanting.
