Other Imaging Findings

Contrast Nephrograms

Acute Pyelonephritis

• Acute pyelonephritis consist 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.

Urography

Xanthogranulomatous Pyelonephritis

• 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.
