Simultaneous uroflowmetry and urinalysis with single specimen – A prospective evaluation of automatic urine strip analyzer of ORUBA INALYS: Uroflowmetry-urinalysis combined device

Objective: To evaluate the consistency of the urinalysis results performed with the ORUBA INALYS device, (Oruba, Ankara, Turkey) which can perform urinalysis and uroflowmetry simultaneously, with the analysis results performed with the SYSMEX UC3500 automated urine chemistry analyzer (Sysmex, Kobe, Japan). Material and methods: In this prospective study, urinalysis of 50 male patients with lower urinary tract symptoms were evaluated. The parameters of glucose, pH, urobilinogen, bilirubin and ketone, leukocyte, protein, and blood were measured with ORUBA INALYS, and the same urine specimens collected from ORUBA INALYS by a special setup were sent to the laboratory for urinalysis with Sysmex UC-3500 to assess the concordance of the results between two devices. Results: Urinalysis results in ORUBA INALYS device in terms of glucose, pH, urobilinogen, bilirubin, and ketone parameters were shown to achieve 100% agreement within ±1 category with SYSMEX UC3500 whereas these values were slightly decreased to 88%, 96%, and 98% for leukocyte, protein, and blood, respectively. Among the calculable weighted kappa values for the test parameters, the highest value was found for glucose and followed by blood, pH, leukocyte, and specific gravity respectively. Conclusion: Significant consistency of the urinalysis results obtained from ORUBA INALYS with those obtained from device SYSMEX UC3500 shows the reliability of the urinalysis performed with ORUBA INALYS. ORUBA INALYS could minimize costs and workload, provide time save and reduce plastic waste.
