What causes acute lobar Nephronia?

Acute lobar nephronia (ALN) also known as acute focal bacterial nephritis is “an acute localized non –liquefactive infection of the kidney caused by bacterial infection” ¹. It is considered a midpoint in the spectrum of upper urinary tract infection (UTI) between acute pyelonephritis(APN) and intrarenal abscess.

Can you see pyelonephritis on ultrasound?

Acute pyelonephritis and acute ureteral obstruction often present with similar clinical and urographic findings. Ultrasound, however, can easily detect the presence of obstruction as well as demonstrate characteristic findings suggestive of acute pyelonephritis, and thus allows differentiation.

Can a normal ultrasound scan detect acute pyelonephritis?
