Flashcards in Imaging in Renal and Urology Deck (42):
1

What is the first line test for renal colic

KUB x ray
(with or without IV contrast)

2

Where do ureteric calculi usually get stuck

the pelviureteric junction
pelvic brim
vesicoureteric junction

3

What other pathologies may stimulate calculi

pheboliths, lymph nodes, uterine fibroids and arterial calcification

4

What is the definitive test to confirm a symptomatic ureteric calculus

non contrast CT

5

What is the negative aspect of CT

very high dose radiation

6

What is the prefered test of pyelonephritis

US

7

What is the preferred test of gynaelogical diseases

US

8

What is the preferred test of gynaelogical diseases

US

9

How do you investigate macroscopic haematurea

CT urography (kindeys, collecting systems and ureters)
cystoscopy ( bladder and urethra)

10

When would you use a ureteroscopy

to confirm tumour if not sure after CTU
to ablate tumours if patient cannot have nephrourectomy

11

Describe the technique of CT urography

First scan before contrast - detects renal or ureteric coliv
Then do a second CT with contrast for tumours

12

How do you investigate macroscopic haematurea in over 50s

CT urography (kindeys, collecting systems and ureters)
cystoscopy ( bladder and urethra)

13

Describe the technique of CT urography

First scan before contrast - detects renal or ureteric colic
Then do a second CT with contrast for tumours

14

How would you investigate a case of macroscopic haematuria in a person under 50

US - renal calculi and paranchymal tumours
Cystoscopy - tumours
CTU only when all other investigations normal and MA persists

15

How would you investigate a case of macroscopic haematuria in a person under 50

US - renal calculi and paranchymal tumours
Cystoscopy - tumours
CTU only when all other investigations normal and MA persists

16

When is MR urography useful

it doesnt require contrast or radiation so is useful in patients who have a contrast allergy and renal impairement and pregnancy

17

What are the disadvantages of MR urography

less sensitive than CTU for small calculi or upper TCC so only use when CTU contraindicated

18

What are the disadvantages of MR urography

less sensitive than CTU for small calculi or upper TCC so only use when CTU contraindicated

19

What size of renal tumours rarely metastasize

those less than 3cm
follow up rather than operate

20

What are renal masses containing fat usually

angiomyolipomas

21

What are fluid dense masses usually

cysts

22

What are fluid dense masses usually

cysts

23

What are signs of malignancy

complex cysts, solid areas, thick septa
solid non cyctic masses more than 3cm

24

What are signs of malignancy

complex cysts, solid areas, thick septa
solid non cyctic masses more than 3cm

25

What investigation is used to stage tumours

CT

26

What is the role of imaging in renal impairement

Pre renal - MR angiography to detect RAS
Renal - biopsy US guided
Post- US (hydronephrosis) CT

27

What investigation can be used to distinguish between acute and chronic renal impairement

US - asseses renal size

28

What investigation can be used to distinguish between acute and chronic renal impairement

US - asseses renal size

29

What is usually used to image the scrotum and testes

30

What is the appearance of testis and or epididymitis on US

31

What is the appearance of testicular torsion on US
