Epithelial cells form the lining of the urinary tract. Three types may occur in urine: squamous epithelial cells, transitional epithelial cells and renal tubular epithelial cells. Some laboratories do not distinguish between the three types of cells and simply report "epithelial cells" in general. [104]
Urine typically contains epithelial cells shed from the urinary tract, and urine cytology evaluates this urinary sediment for the presence of cancerous cells [2] [3] from the lining of the urinary tract, and it is a convenient noninvasive technique for follow-up analysis of patients treated for urinary tract cancers.
A urine test strip or dipstick is a basic diagnostic tool used to determine pathological changes in a patient's urine in standard urinalysis. [1] A standard urine test strip may comprise up to 10 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample.
The most common type of cast, hyaline casts are solidified Tamm–Horsfall mucoprotein secreted from the tubular epithelial cells of individual nephrons. Low urine flow, concentrated urine, or an acidic environment can contribute to the formation of hyaline casts, and as such, they may be seen in normal individuals in dehydration or vigorous exercise.
The white in the bladder is contrast. Bladder cancer is any of several types of cancer arising from the tissues of the urinary bladder. [1] Symptoms include blood in the urine, pain with urination, and low back pain. [1] It is caused when epithelial cells that line the bladder become malignant.
A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system, and specimens are easy to obtain. [1] Common urine tests include the routine urinalysis, which examines the ...
Podocyte. Podocytes are cells in Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. Podocytes make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place. [1] Bowman's capsule filters the blood, retaining large molecules such as proteins while smaller molecules ...
Decoy cells. Decoy cell cytology, using Papanicolaou stain. The high nuclear to cytoplasmic ratio makes it resemble cancer (thus the name "decoy cell") but the inclusion body distinguishes it. Decoy cells are virally infected epithelial cells that can be found in the urine. Decoy cells owe their name to their strong resemblance to cancer cells ...
