Acute renal failure secondary to acute pyelonephritis.
A six year-old girl presented with acute oliguric renal failure, secondary to acute, non-obstructive pyelonephritis. Evidence for pyelonephritis as the cause of renal failure included: the evolution of typical changes on serial intravenous pyelograms, an acute interstitial inflammatory exudate on percutaneous renal biopsy, and gram-positive cocci on gram stain of the biopsy tissue. Although a specific causative organism was not conclusively identified, enterococcus was isolated from the initial catheterized urine specimen. The patient recovered from the acute illness but was left with impaired renal function, hypertension, and cortical scarring. Acute, non-obstructive pyelonephritis can produce acute renal failure in children and must be considered in the differential diagnosis of this syndrome.
