1. Urinary tract imaging

2. *Mega ureter

3. *Retrocaval ureter (right ureter ) behind inferior vena cava.

4. *PUJ obstruction

5. *Duplication of the right kidney

6. Horse shoe kidney :-. lower poles fused. low positioned kidneys
Horse shoe kidney :-*lower poles fused *low positioned kidneys *parallel to spines. *malrotated medially

7. *Right kideny is ectopic(presacrally located)&bilateral hydronephrosis.

8. *Polycystic kidney disease

9. *Cobra head:-rounded or elliptical dilatation of lower end of ureter with thin lineal filling defect around it with proximal dilatation of the rest of ureter.

10. Same as previously

11. :*Ectopia vesica :-bladder located at low position with separartion of symphysis pubis.

12. *Cobra head: rounded or elliptical dilatation of lower end of ureter with thin lineal filling defect around it with proximal dilatation of the rest of ureter

13. *Bilateral megaureter

16. *Ectopic left kidney:-ureter is short (small arrow)

17. Retrocaval ureter:- (right ureter ) behind inferior vena cava.

18. *Hydronephrosis + ectopic left kidney

19. *PUJ obstruction&retrocaval ureter

20. *Hydronephrosis&ectopic kidney

21. *PUJ obstruction

22. Horse shoe kidney :-. lower poles fused. low positioned kidneys
Horse shoe kidney :-*lower poles fused *low positioned kidneys *parallel to spines. *malrotated medially

23. *PUJ obstruction

24. Horse shoe kidney :-. lower poles fused. low positioned kidneys
Horse shoe kidney :-*lower poles fused *low positioned kidneys *parallel to spines. *malrotated medially

25. *PUJ obstruction

26. *Duplication of right kidney

27. *PUJ obstruction

28. *Duplication (incomplete)

29. *Bladder shistosmomiasis (calcification most important feature)

30. *Dilated pelvicalyceal system with filling defect

31. *Irregular filling defect in P.C.Stumour

32. *Filling defect in P.C.S :- stone(because it is regular ,if irregularblood clot or tumour .

33. *Stone in the left kidney

34. *PUJ obstruction

35. *Vesico ureteral junction stone on CT

36. *Stone without hydronephrosis (left) and stone+ hydronephrosis (right) because of dilatation of P.C.S

37. *Hydronephrosis:-dilated pelvicalyceal system on US

38. *Phlebolith (arrow):-round lucent centre,,it represents calcified thrombus in pelvic vein.
