Recent Advances in Urinalysis as a Diagnostic Indicator of Renal Diseases

Abstract Urinary sediments may be associated with the pathogenesis of renal diseases. It is important to examine the presence of dysmorphic red blood cells, macrophages, tubular epithelial cells, fibrin casts, glomerular epithelial cells, and ammonium acid urate crystals in urine for evaluating the clinical status of glomerulonephritis. Collecting evidence regarding the relationship between urinary sediments and renal disease activity may provide cost-effective and prompt clinical information to improve clinical practice.
