Tubular cells
Active
Description
The tubular cells seen in casts are usually from the collecting tubes, but cells originating from the proximal tubules or any other sections (prior to the collecting tubes) of the nephron is possible. With the PAP stain, Schumann subdivides renal tubular cell casts in RTC and necrotic RTC casts.
A few hyaline RTC casts or RTC casts can occasionally be found in a healthy person's urinary sediment. In this context, these casts have no more clinical meanings than the hyaline casts. The renal tubular cell casts are not associated with a precise pathology, but are found in multiple conditions that affect the renal tubules. The RTC casts are non specific. Pathologies associated with the presence of these casts include acute interstitial nephritis, acute transplant rejection, and tubular necrosis. Necrotic RTC casts are seen in acute tubular necrosis and in nephrotoxic tubular diseases.
The typical renal tubular cell casts are described as hyaline matrix casts, showing two rows of well delimited tubular cells. The two rows criteria is not reliable because the white blood cell casts can also appear with this particularity. Sequestrated tubular cells in a hyaline matrix is possible, but recent studies indicate that the majority of casts of this type are composed of cells fixed to the surface of the casts.
