Imaging in Renal and Urology Flashcards
What is the first line test for renal colic
KUB x ray
with or without IV contrast
Where do ureteric calculi usually get stuck
the pelviureteric junction
pelvic brim
vesicoureteric junction
What other pathologies may stimulate calculi
pheboliths, lymph nodes, uterine fibroids and arterial calcification
What is the definitive test to confirm a symptomatic ureteric calculus
non contrast CT
What is the negative aspect of CT
very high dose radiation
What is the prefered test of pyelonephritis
US
What is the preferred test of gynaelogical diseases
US
What is the preferred test of gynaelogical diseases

How do you investigate macroscopic haematurea
CT urography (kindeys, collecting systems and ureters) cystoscopy ( bladder and urethra)
When would you use a ureteroscopy
to confirm tumour if not sure after CTU
to ablate tumours if patient cannot have nephrourectomy
Describe the technique of CT urography
First scan before contrast - detects renal or ureteric coliv
Then do a second CT with contrast for tumours
How do you investigate macroscopic haematurea in over 50s
CT urography (kindeys, collecting systems and ureters) cystoscopy ( bladder and urethra)
Describe the technique of CT urography
First scan before contrast - detects renal or ureteric colic
Then do a second CT with contrast for tumours
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

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
