Examination of the urinary sediment is a simple and indispensable tool in the diagnostic approach to patients with asymptomatic haematuria. Various glomerular and nonglomerular diseases can cause haematuria. A well-trained expert can distinguish between these two forms of haematuria by examining the urinary sediment under a simple light microscope. In glomerular haematuria, dysmorphic erythrocy...

INTRODUCTION The detection rate and associated factors of at least one sperm in urinary sediment is not well-known in real clinical practice. AIMS The aim of the present study was to evaluate the clinical features associated with the presence of sperm in urinary sediment in a large number of samples. METHODS We conducted a cross-sectional study at Tokyo Saiseikai Central Hospital. We identi...

Sir, The common digital camera is a useful tool that assists urinary sediment analysis. Three years ago, in our laboratory , we started taking pictures of urinary sediment. With the database, we were able to organize a Urinalysis Atlas that is constantly updated with new pictures. This atlas has been used to teach our trainees. The photos, taken with a basic Kodak digital camera, have been usef...

A urinary sediment examination is an important type of non-invasive, repeatable morphological examination. It is necessary to accurately classify and measure urine components, such as epithelial cells, non-epithelial cells (blood cells), casts, salts/crystals, and microorganisms. The clinical significance of a urinary sediment examination is twofold. First, this examination is used to screen fo...

1,001 consecutive women seen in a V.D. clinic were screened for gonorrhoea by cultures of urinary sediment, the endocervix, and anal canal. Recovery of Neisseria gonorrhoeae on culture of urinary sediment was 81-7 per cent. as productive as culture of the endocervix, and 79-2 per cent. compared to endocervical and anal canal culturing. Urogenital symptoms were present in 55-1 per cent. of women...

Urinary analysis is one of the most requested tests in the clinical laboratory. This test includes the physical, chemical and microscopic analysis of urine. This last one allows for the observation of urinary sediment (US) in search of formed elements (cellular cast, leukocytes, etc.), with different diagnostic uses. Urinary analysis can be assessed by manual or automated methods. In the labora...

The miRNAs in urinary sediment are easy to obtain, which provides a new approach to searching for non-invasive biomarkers of IgA nephropathy (IgAN). Compared with normal controls (n = 3), 214 different miRNAs in the urinary sediment of IgAN (n = 9) were found by miRNA chip assay. By quantitative PCR analysis, miR-25-3p, miR-144-3p and miR-486-5p were confirmed to be significantly higher in IgAN...

BACKGROUND AND OBJECTIVES Urine microscopy is the oldest and one of the most commonly used tests for differential diagnosis of acute kidney injury (AKI), but its performance has not been adequately studied in the setting of AKI. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Fresh urine samples were obtained from 267 consecutive patients with AKI, and urinary sediment was examined. The cause o...

…When the patient dies the kidneys go to the pathologist , but while he lives the urine is ours. It can provide us day by day, month by month, and year by year with a serial story of the major events within the kidney. The examination of the urine is the most essential part of the physical examination of the patient… (Thomas Addis, 1948) This quote from Prof. Addis starts the magnificent histor...
