Acute Interstitial Nephritis

 

Kidney diseases that involve structures within the kidney yet outside the glomerulus are broadly referred to as tubulointerstitial. These diseases generally involve tubules and/or the interstitium of the kidney and spare the glomeruli. By far the most common form of tubulointerstitial inflammation is immunologic from lupus or Goodpastures or from drug hypersensitivity.

Normal kidney size by ultrasound examination generally favors but does not prove a diagnosis of acute (thus potentially reversible) kidney disease. The role of imaging in these patients is to exclude obstruction as the cause of renal insufficiency that may be reversible with urinary tract decompression.
