hematuria
palpable mass
RCC echogenicity
majority are isoechoic, but can be hypo/hyper

most common type of RCC
clear cell
most common malignancy of urinary system
transitional cell carcinoma
most common tumour area TCC
bladder, trigone and posterior bladder wall
s/s TCC (4)
hematuria, frequency, dysuria, suprapubic pain
describe TCC is it solitary/multifocal?
uni/bilateral?
multifocal, bilateral
t/f TCC rarely invades renal vein
true
rare tumour, what’s it associated with? is it malignant or benign?
juxtaglomerular tumour
severe hypertension because tumour in cells that secrete renin. benign
tumour associated with obesity/steroid therapy
renal sinus lipomatosis
in which tumour is staghorn calculi present?
adenocarcinoma
adenocarcinoma associated with
stones
what is the most common benign renal tumour
renal adenoma
which tumour has the same triad of symptoms as RCC?
angiomyolipoma
t/f angiomyolipoma may hemorrhage with growth
true
lymphoma sono app
homo anechoic nodules in parenchyma (solitary or multiple)
most common renal parenchymal tumour
RCC
RCC affects men or women more? what about TCC?
men for both
watch and wait approach used for RCC if tumours are
<3cm
how to characterize RCC
MRI or CT
is it possible to distinguish RCC from benign renal tumours with imaging tests?
NO except you can with angiomyolipoma because CT/MRI can detect fat composition
patients with ACKD may develop
RCC
RCC staging
1-confined within capsule
2-invasion perinephric fat
3-LN involement
4-invasion adj organs
what does renal sinus lipomatosis occur secondary to?
renal parenchyma atrophy or destruction of parenchyma
D/D of TCC (3)
blood clots
sloughed papillae
fungus balls
the majority of TCC in ureter are located
lower third
what is TCC associated with? (2)
hydronephrosis and hydroureter
t/f TCC bladder tumours are usually more invasive than superficial
FALSE
70% superficial
TCC bladder tumours sonographically (3)
nonmobile focal mass (if you move pt to decub and it moves, probably a clot)
may calcify
vascular stalk
bladder outlet obstruction causes (4)
enlarged prostate
stones
tumours
scar tissue
what is the second most common malignant tumour
SCC
SCC sono app
diffusely enlarged kidney, often stone often present
history of chronic UTI causes what? what will you likely see?
adenocarcinoma, stone
what tumours look like RCC (2)
renal adenoma
oncocytomas
tumour containing various proportions of adipose tissue, smooth muscle, and blood vessels
angiomyolipoma
tumours that can be exophytic or within parenchyma
angiomyolipoma
women more often in which condition
lymphoma of bladder
