2. Topics KUB IVP: intravenous pyelography Ultrasonography
CT scan & MRI studies
Renal scan

3. KUB KUB stands for: kidneys, ureter & bladder.
No contrast material is used, it is the same for plain abdominal X-ray to show the different abdominal & pelvic organs as soft tissue shadows.
It is useful also to show radio-opaque renal stones.

5. IVP
**What is an Intravenous Pyelogram (IVP)? An intravenous pyelogram (IVP) is an x-ray examination of the kidneys, ureters and urinary bladder that uses contrast material.

6. How IVP will help in renal cases ??

7. IVP **How does the procedure work?
In the IVP exam, iodine injected through a vein in the arm collects in the kidneys, ureters and bladder, giving these areas a bright white and sharply defined appearance on the x-ray images.
**How is the procedure performed?
outpatient basis.
The patient is positioned on the table.
The contrast material is then injected, usually in a vein in the patient's arm, followed by additional still images.
hold very still.
As the contrast material is processed by the kidneys a series of images is taken.

8. IVP
**Nephrogram: the contrast is condensed in the tissue of the kidney within 5 minutes **Pelvicalycal pyelograph: calyces: major 3 ( upper- middle- lower) minor :6-12 cup shaped at the end of major calyces each minor calyx has a neck and expanded extension (part of renal papilla) Pelvis of ureter : funnel shaped narrowing towards it is medial inferior angle 3 Constrictions of ureter: 1- at the junction with the renal pelvis. 2- as the ureter cross the pelvic brim at the bifurcation of the iliac artery. 3- as it enters the bladder.

14. Ultrasonography
Initial study to evaluate kidney size, nature of renal masses (solid or cystic)
Doppler U/S to assess renal vasculature.

22. MRI Angiography

23. Renal scan
A renal scan is a nuclear medicine exam in which a small amount of radioactive material (radioisotope) is used to measure the function of the kidneys.
