Chapter 6: 2.2 - Organized: Epithelial Cells Flashcards
(27 cards)
-marked increase of epithelial cells indicates?
inflammation of portion (where cells are derived)
cells derived from the linings of genitourinary system
Epithelial cells
most frequently seen and least significant epithelial cell
squamous cells
- largest cells in urine sediment
- flat or irregulary shaped
squamous cells
exessive number of squamous suggests.
improper collection by clean-catch method
- squamous cells whose surface is coverd by coccobacillus (Gardnerella vaginalis)
- granular, irregular appearance indcated pathologic condition
clue cells
Clue cells are what kind of cells?
Squamous cells
epithelial cells
transitional epithelial cells are also known as
urothelial or caudate cells
-originates from the lining of renal pelvis, calyces, uereters and bladder, upper urethra of male
Transitional epithelial cells
which is larger?
TEC or SEC
SEC
- polyhedral with central nucleus
- ability to reabsorb large quantities of water
TEC
small number of TEC in the urine
normal/abnormal
normal - due to cellular sloughing
-increased TEC w/ abnormal morphology (w/ vacuoles/irregular nuclei) may indicate..
malignancy (carcinoma) or viral infection
- usually round
- slightly larger than WBC
- single round eccentrically located nucleus
RTE
cells from the PCT or DCT
RTE
- rectangular in shape
- cytoplasm is coarsely granular
- often resemble casts
RTE
RTE:
Which is larger in size?
cells from (DCT/PCT)
PCT
presence of > 2/hpf RTE cell indicates active ___
tubular injury or degeration
most significant; presence of RTE indicates (2)
Tubular necrosis and
Renal graft rejection
What kind of cell is an Oval Fat Body
Renal Tubular Epithelial cell
may also be macrophages or leukocytes that have ingested lipids or degenerated cells, undergone fatty degeneration
-lipid contiaining renal tubular cell; seen w/ free floating fat droplets
Oval Fat Bodies
What stain is used to confim Oval Fat bodies? (2)
Sudan III or
Oil Red O (polarized microscopy)
Oval fat bodies may indicate..
nephrotic syndrome
-associated with damage to glomerulus caused by nephrotoc syndrome, severe tubular necrosis, Diabetes Mellitus, trauma cases
Lipiduria
