Abstract: Urine carries rich information of human metabolism, while urine examination facilitates the diagnosis, classification and efficacy observation for acute kidney injury (AKI) and chronic kidney disease (CKD). Urine sediment has characteristics of convenience, screening, qualitation, localization, which provides important basis for distinguishing the source of RBC, assisting in the diagnosis of renal glomerular diseases, urinary infection and various causes of renal parenchymal injury. The urine sediment microscopy based on renal tubular epithelial cell (RTEC) and granular tubular (GC) counts mainly includes urinary sediment score (USS), tubular scoring index (CSI), urine microscopy score (UMS), and continuous urine sediment microscopy score (MicrExUrSed), which can provide laboratory information for early diagnosis, etiological differentiation, staging evaluation, and prognosis assessment of AKI.
