Renal Flashcards
IVU “ iodine”
Nephrogram =
Pyelogram =
Cortex & medulla
Pelvicalyceal system
KUB shows
Opacified mass at area occupied ureter
We can confirm ureteric stone by :
IVU
Which can show
Ureteric stone , hydroureter , hydronephrosis
IVU
Shows copra head sign
Describe:
Dx:
This condition may be associated with :
Dilation at the distal end of the ureter
Ureterocele
Duplex collecting system
We see that left kidney crossed to the RT side by IVU
This is called :
Crossed renal ectopia
IVU
PUJ obstruction
Describe :
Most common in :
Dilated pelvicalcyceal system & cubbing with abrupt diameter
More common in male ; functional obstruction present at any age.
Uss
PUJ obstruction
Describe :
Dilated pelvis with communicating calyces.
Abrupt diameter
Hydronephrosis due to PUJ obstruction
Uss
Dilated communicating calyces
Can be
-
-
Hydronephrosis
PUJ obstruction “ abrupt diameter “
How could you know renal pelvis obstruction by CT
CT axial abdomen with IV contrast
Rt side : dilated pelvis with reduced cortical enhancement
Left side : delayed pyelogram
( RT renal pelvis obstruction )
Staghorn stone in kidney
Describe by KUB :
Bilateral radiopaque stone occupying pelvicalcyceal system
Staghorn stone
Uss kidney
Describe :
Hyperechoic stone occupying the pelvicalyceal system with large posterior acoustic shadow.
Kidney stone
By CT
Describe :
CT axial abdomen without IV contrast
Hyperdense mass occupy the pelvicalyceal system
Nephrocalcinosis
By KUB
Describe
Punctate calcification occupying the renal parenchyma
“ indicate Hypercalcemial”
Same as in CT
Does nephrocalcinosis have posterior acoustic shadows ?
No posterior acoustic shadow
Punctate hyperechoic lesions occupying the renal parenchyma
Without posterior acoustic shadow
Multiple kidney stones
Uss
Describe :
Multiple hyperechoic stones with posterior acoustic shadow
Kidney stone complicated with hydronephrosis
( obstructive renal stone with hydronephrosis )
Uss :
Hyperechoic mass with posterior acoustic shadow occupy the renal pelvis , & multiple communicating dilated calyces
Lt persistent nephrogram & delayed pyelogram
The hydroureter & hydronephrosis occur
Just focus , you see :
Dx :
Small stone at the vesicoureteric junction
Acute left urinary tract obstruction due to Left vesicoureteric junction stone
Polycystic kidney disease
CT describtion
Multiple bilateral non enhanced hypodense cystic masses occupying both kidneys with renal enlargement
