Other Imaging Findings
Contrast Nephrograms
Acute Pyelonephritis
- Acute pyelonephritis consists of focal areas of striated or wedge-shaped hypoperfusion, resulting in a characteristic striated nephrogram.
- Striations result from stasis of contrast material within edematous tubules that demonstrates increasing attenuation over time.
- The infected kidney is usually enlarged, and there is often stranding in the perinephric fat.
- Delayed views of the infected kidney may demonstrate a nephrogram with increased attenuation.
Intravenous Pyelography
Intravenous Pyelography (IVP) is done to diagnose an intra-renal or peri-nephric abscesses. IVP is a very sensitive radiological test for this purpose.[1]
Urography
Urography can be used to diagnose patients with acute pyelonephritis and in some cases with xanthogranulomatous pyelonephritis[2]
- Classic urographic triad in diffuse xanthogranulomatous pyelonephritis consists of unilaterally decreased or (more commonly) absent renal excretion, a staghorn calculus, and a poorly defined mass or diffuse renal enlargement.
