Clinical Information

A disorder characterized by an infectious process involving the kidney.

An acute or chronic inflammatory process affecting the kidney. It is

caused by bacteria and in most cases it is the result of a urinary tract

infection. Signs and symptoms include fever, chills, flank pain, painful

and frequent urination, cloudy or bloody urine, and confusion.

Diffuse or local inflammation and edema of the interstitial tissue of the

kidney, including the tubules.

Inflammation of the interstitial tissue of the kidney. This term is generally

used for primary inflammation of kidney tubules and/or surrounding interstitium.

For primary inflammation of glomerular interstitium, see glomerulonephritis.

Infiltration of the inflammatory cells into the interstitial compartment results

in edema, increased spaces between the tubules, and tubular renal dysfunction.

Inflammation of the kidney and its pelvis due to infection.

Inflammation of the kidney involving the renal parenchyma (the nephrons);

kidney pelvis; and kidney calices. It is characterized by abdominal pain; fever;

nausea; vomiting; and occasionally diarrhea.

Inflammation of the kidney pelvis and kidney calices where urine is collected

before discharge, but does not involve the renal parenchyma (the nephrons)

where urine is processed.
