What type of RTE cells appear in collecting duct samples?

• A. Pyramidal cells
• B. Columnar cells
• C. Cuboidal cells
• D. Squamous cells

Answer: (C)

Renal tubular epithelial (RTE) cells are essential for the identification of kidney health and pathology, particularly in the context of urinary sediments. Collecting ducts in the kidneys primarily consist of principal cells and intercalated cells, both of which can be classified as cuboidal cells. Cuboidal cells are characterized by their cube-like shape, which contributes to their function in reabsorption and secretion processes within the collecting ducts. These cells play a crucial role in maintaining fluid and electrolyte balance in the body. The presence of cuboidal RTE cells in the urinary sediment can indicate various conditions such as tubular damage, but they are fulfilling their normal role in the collecting duct. Other cell types mentioned, such as pyramidal, columnar, or squamous cells, are not representative of the characteristic cells found in the collecting ducts. Therefore, recognizing cuboidal cells as the correct choice highlights their specific role and identification in this anatomical area of the kidney.
