Anatomy
· Renal arteries @ L1/2
o Accessory renal artery in 20-30%
· 3 Us as connections from/to bladder
o Ureters
o Urethra
o Urachus (?patent, ?cyst)
Imaging
· Plain films
· CT
o Indications
§ masses
§ stones
§ haematuria
§ hypertension
· Contrast enhanced studies
o Contrast will take 20-30min to be excreted into renal calcies
o for vascular studies/ luminal opacification
o IV urography
§ Haematuria
§ Obstruction
o Antegrade or retrograde pyelography
§ Contrast into renal pelvis (ante)/ bladder (retro)
o Micturating ctsto urethrography
§ Post urethral valves (neonatal male)
o Ascending urethrography
o Risks
§ n+v
§ Pruritus
§ hypotension
§ pulmonary oedema
§ contrast induced nephropathy
· US
o renal masses
o infection
o obstruction
o haematuria
o renal failure (due to no contrast being used)
o vascular imaging
· MRI
