This document provides an overview of renal ultrasound techniques. It discusses several ultrasound modes including B-mode, Doppler, and 3D ultrasound that are used to image the kidneys. Normal kidney anatomy is described for fetal, infant, and adult kidneys. Renal ultrasound is also used to diagnose many renal disorders including congenital, traumatic, inflammatory, neoplastic, and other parenchymal diseases. Doppler ultrasound can assess blood flow in the renal arteries and veins and is useful for evaluating transplanted kidneys and other vascular conditions. The document expresses appreciation to colleagues for their work.

2. Its , a great highly appreciated
work

4. Renal ultrasound

5. What is ultrasound ?

6. Sound is a wave

8. Ultrasound is also a wave
of high frequency than human hearing limit

10. Ultrasound

12. A-mode : in ophthalmology

13. M-mode in cardiology

14. B-mode : brightness mode [90]

18. Kidney ultrasound :
• B mode ultrasound 90
• Doppler - spectral Doppler NO 90
- color Doppler
- power Doppler
• 3D ultrasound
• Renal Elastogram

19. US of Normal kidney

22. Fetal kidney Infant kidney

25. Normal variants

26. Ultrasound is used in diagnosis
of many renal disorders
• Congenital
• Traumatic
• Inflammatory
• Neoplastic
• Others
Parenchymal disease

27. Renal parenchymal disease basically appear echogenic
There are three grades of renal parenchymal disease

28. ???

29. 1843
Color Doppler US

30. • Renal artery assessment
• Renal transplants
• Renal vein thrombosis
• Renal failure
• Obstructive uoropathy
• Tumor and infectious pathology
• Ureters

31. RENAL ARTERY
examined at
• Main renal artery
• Segmental branches
• Upper ,middle &lower renal
poles

32. SPECTRAL STUDY ++++
The normal peak systolic velocity of the main renal artery is less than 150 cm/sec.
The resistive index is less than 0.70 .

33. Resistive index
RI = Less than 0.7

34. Causes of increased
resistance :
1- Acute and chronic
parenchymal disease
2- Obstruction
3- Renal vein thrombosis
?????????

36. Color Doppler &
Transplanted kidney

37. Complications of allograft
• Site of anastomosis
- Artery
- Vein
- Ureters
• Renal tissue
• Surroundings

38. Doppler can assess the AF fistula
for patients on dialysis
Color swirl
High flow volume

39. Ultrasound is an excellent guide in
renal intervention & biopsy

40. We are on the same vision
on the way to
open a dedicated unites for :
- Ultrasound interventions
- Color Doppler
- Neuroradiology
- women imaging
- etc ……
