Imaging

Question 1

Renal colic
1st line?
definitive? - avoid when? use ? instead?

Answer 1

1st line = KUB Xray
CT non contrast = definitive
- dont use in pregnancy and young females - US/MRI instead

Question 2

Imaging for macroscopic haematuria

• if over 50?
• if under 50?
• pregnancy/contrast allergy?

Answer 2

over 50:
- CT urography (CTU) and cystoscopy

under 50:

• US and cystoscopy (CTU not justified because incidence of urothelial tumours of kidney is very low)
• CTU only when US and cystoscopy are normal but macroscopic haematuria persists

pregnancy:
MR urography - no contrast and no radiation
but this is less sensitive so only use when CTU is contraindicated
