Q

Squamous epithelial cells
size?

nucleus?

seen on?

can?

origins?

A

largest
sediment
nucleus size of rbc
easily seen on low power 10x

can FOLD/looks like cast

Origins - linning of vagina/urethra

17
Q

Clue cells

A

squamous cells with bacteria
pathologic in large numbers, not reported in urine

bacterial vaginosis/gardinella

18
Q

Transitional cells
smaller than?
nucleus location?
defined?
numerous?

amounts?

hard to diff from?

originate in?

A

smaller than squamous
central located nucleus
well defined edge
numerous folds

Norm in small amounts: <0-2

hard to differentiate from RTE

Originate in: pelvis/top urethra

19
Q

Increased numbers of transitional cells

A

invasive urologic procedure (catheters) not pathological

abn morphology = viral infection/malignancy

20
Q

Renal tube cells
vary based on?
larger than?

shape?
nucleus?
normal range?
> =

A

vary in size based on location
larger than wbc
not round/flattened edge
eccentric nucleus
0-2 normal

> 2 damage to renal tubes

21
Q

T/F RTE reabsorb filtrates and may contain elements: bilirubin yellow: hemosiderin yellow-brown granules

A

true

22
Q

Oval fat body
RTE that has…..

highly r/p

seen among..

A

RTE that has lipids absorbed from golm. filtrate

highly refractile

highly pathogenic

seen among free fat droplets/casts

23
Q

Lipiduria

A

fat in urine

nephrotic syndrome
tube necrosis
diab mellitus
trauma bm fat
lipid storage disease

24
Q

How do you stain oval fat bodies

A

oil red O or sudan III
triglyercides/neutral fats

25
Q

Oval fat body special features

A

polarize cholesterol - characteristic maltese cross

confused w starch/crystals

26
Q

Bacteria
what stain?

A

not norm in urine
rt >2hr
should also see wbcs

Nitrite/leuk esterase

Sternheimer stain

27
Q

Yeast

hyphae appear ?

mainly?

diab
immuno
yeast

what should be present

A

small refractile oval element
budding

hyphae appear branched
(rbc lyse with acid)

mainly candida albicans
-diabetes mellitus
-immuno compromosied
-yeast infection

wbc should be present

28
Q

mucus

what type of substance where?

major consitintuent?

low?

more in?

significance?

A

protein substance prod by glands/epi cells of lower genit tract RTE

major constitnuent - tamms-horsfall

low refractile index

low light source
more in females

no clinical significance

29
Q

Sperm

shape?

motility?
significance?

increase numbers may produce?

consquences?

A

oval slightly tapered head long tail
not motile (urine toxic)
not clin significant

inc may produce “pos” protein (sometimes only reported when this happens)

legal consequences sometimes possible
