6. Normal

7.  Normal PUT

8.  Normal IVU

9. Full bladder and post-voiding

10. Male urethrography

11. Congenital

12. IVP splaying and smooth stretching of the middle and lower calyx of the
LT kidney>>>benign mass lesion(cyst) CT shows simple cortical renal
cyst
Simple renal cyst

13. IVP shows bilateral splaying and smooth stretching of calyces >>>benign mass
lesion(multiple cysts) CT shows bilateral multiple variable size renal cysts replacing
renal parenchyma
polycystic kidney

14.  IVP showing
duplicated RT pelvi-
calyceal system with
single RT ureter
….incomplete
duplication .

15.  IVP showing complete
duplication of the RT
pelvicalyceal system with
double RT ureter showing
two UB openings, and
incomplete duplication
on the LT side

16. Rt.ectopic kidney
IVP : Rt renal pelvi-calyceal
system is seen lower in
position with normal
excretory function>>>Ectopic
RT kidney

17. IVP : Lt renal pelvi-calyceal
system is seen crossed to the
contra lateral side with
normal excretory
phase>>>Crossed ectopia of
the LT kidney

18. Tissue Bridge
Across Midline
Causes Abnormal
Orientation of
Renal
Axis….horseshoe
kidney

19.  IVP showing moderate
hydronephrotic changes
with arrest of the
contrast media at the
pelvi-ureteric junction
denoting PUJ
obstruction.

20. Stones & obstructive

21.  Plain KUB
showing
radio-opaque
stone in soft
tissue shadow
of the LT
kidney

22.  Plain KUB showing
dense radio-opaque
stone in the RT
pelvicalyceal
system……..stag horn
stone.
 Another dense stone
seen in the soft tissue
shadow of the LT
kidney

23.  Plain KUB showing
dense radio-opaque
stone in the RT
pelvicalyceal
system……..stag
horn stone.
 Another dense
stone seen in the
soft tissue shadow
of the LT kidney

24.  plain KUB showing two
radio-opaque stones in
the region of the upper
part of the LT ureter
opposite to transverse
process of L3.

25.  Plain KUB showing
dense radio-opaque
shadow seen in the LT
side of the pelvis
suggesting LT distal
ureter( vesicoureteric
junction) stone

26.  Plain pelvic film showing multiple radio-opaque stones
seen in the soft tissue of the urinary bladder

27.  IVP showing marked
LT side
hydronephrosis with
dilated LT ureter
down to its distal
end suggesting
distal ureteric
stricture/ stone

28.  IVP showing bilateral
hydronephrosis and
hydroureter . With irregular
trabiculated UB wall
denoting bladder outlet
obstruction

29.  IVP full bladder
film showing
smooth regular
semicircular filling
defect of the UB
base(elevated UB
base) BPH.

30. Urethral stricture
Ascending
urethrocystogram
showing short
segment stricture
in the posterior
urethera with
proximal minimal
dilatation

31. Tumors

32. IVP splaying and destruction of the calyces on the RT side >>>RT
malignant mass lesion CT shows abnormal soft tissue lesion replacing
RT renal parenchyma with central degeneration ….RCC

33.  IVP showing bilateral
hydronephrotic
changes with dilated
both ureters.
 Irregular filling defect
involving the RT
lateral bladder wall
and bladder base
suggesting urinary
bladder carcinoma
