Which element is renal tubular cells in urine?

In urine sediment, the source of the cells tells you where a problem might be. Renal tubular epithelial cells come from the kidney tubules, so finding them in urine indicates tubular shedding due to kidney tubule injury or stress. They’re not typically abundant in healthy urine, so their appearance points to a renal issue rather than a normal contaminant. Other cells reflect different sources: white blood cells suggest infection or inflammation, squamous epithelial cells come from the lower urinary tract or genital tract and are often considered contaminants if many are present, and transitional cells line the renal pelvis, ureter, and bladder. Since these do not originate from the kidney tubules, they don’t indicate tubular injury the way renal tubular epithelial cells do.
