Flashcards in Radiographic Evaluation of Kidney and Ureters Deck (37):
1

imaging is primarily used to _______

assess morphology

2

excretory urography is useful for assessing 

collecting system

qualitative function

3

which 2 views are needed to assess the kidneys

Right lateral - tends to separate kidneys more

VD - separated more and magnified less than DV

4

why is the right kidney not seen consistently 

lies in renal fossa of caudate lobe (silhouettes)

5

where does the left kidney lie in relation to the right kidney

caudal and ventral

6

T/F kidneys are mobile and may change location slightly between exposures

True

7

renal conspicuity is influenced by

amount of retroperitoneal fat

8

how is kidney sized estimated

compare it to L2 in VD view

9

normal kidney size in dog and cat

Dog: 2.5-3.5 x L2

Cat: 2.4-3.0 x L3

10

what is excretory urography

contrast procedure to evaluate the kidneys and ureters

11

T/F excretory urography provide morphologic and functional information

True

functionally only determines qualitative function: yes or no

12

can excretory urology be used in azotemic patients

yes - as long as hydration is adequate

quality decreases as azotemia increases

13

how should patients be prepare for excretory urography

correct hydration deficits

enema

fasting

IVC -in case renal function declines due to contrast medium (rare)

14

what type of contrast medium should be used in compromised patients

non - ionic

15

when is excretory urogram contraindicated

azotemia + dehydration

pheochromocytoma

multiple myeloma

prior allergic rxn to C.M.

16

standard protocol for EU

survey radiographs

inject contrast medium rapidly

immediate VD radiograph

later and VD at 5, 20, and 40 min

17

phases of EU

nephrogram - opacification of functional renal parenchyma

pyelogram - opacification of pelvic recesses, renal pelves, and ureters

cystograms - crude yet helpful, has to end up there eventually but not the reason you do EU

18

EUs are most commonly performed to evaluate the 

pelvis and ureters

19

ectopic ureters detected or not detected

not detected

20

contrast medium indeced renal failure

constant or increasing nephrogram opacity 

no visualization of collecting system

fluid administration recommended

21

polycystic kidney disease detected or not detected

detected

22

renal calculi detected or not detected

detected

23

what can be confused with calculi

iliac aa & vv

seeing them head on

24

EU signs of pyelonephritis

blunt diverticulae

dilated pelvis

25

pyelonephritis detected or not detected

detected

26

hydronephrosis detected or not detected

detected 

27

EU is excellent to assess possible ______

UT trauma

28

what is used to diagnose ectopic ureters

EU

CT
vaginography

29

what causes diffuse increased cortical echogenicity

glomerulo or  interstitial nephritis

dehydration

end stage kidney

30

31

renal neoplasia detected or not detected

32

what is an inherited renal disease seen in long haired cats and cairn terriers

polycystic kidney disease

33

T/F PKD is slowly progressive and irreversible

True

34

how many MHz needed to assess PKD

7.5 MHz

35

what is hydronephrosis

dilation of renal relvis die to obstruction of urinary collecting system 

36

earliest signs detected in which plane

transverse

37

what dis?

hydronephrosis
