Which of the following is NOT a type of epithelial cell found in urine?

Cuboidal epithelial cells are not typically found in urine. In the context of urine analysis, the types of epithelial cells commonly observed include squamous epithelial cells, transitional epithelial cells, and renal epithelial cells.

Squamous epithelial cells, derived mainly from the urethra and the outer layers of the bladder, are often present in urine and can indicate normal sloughing of epithelial cells. Transitional epithelial cells line the bladder and can appear in urine, particularly when there is increased stretch or irritation of the bladder. Renal epithelial cells originate from the renal tubules and can be indicative of kidney health; their presence in urine can suggest a renal pathology if found in elevated numbers.

Cuboidal epithelial cells, however, are not a standard type of cell found in urine samples. They are usually associated with glandular tissues or organs such as the kidney and are more relevant in histological studies rather than urine analysis. Hence, the option regarding cuboidal epithelial cells is correct as the type not typically found in urine.
