Inflammation of the kidneys. The condition may be either acute or chronic and is caused by bacteria or their toxins (e.g., pyelonephritis), autoimmune disorders (e.g., poststreptococcal glomerulonephritis, systemic lupus erythematosus), or toxic chemicals (e.g., pesticides, mercury, arsenic, lead, alcohol, nonsteroidal anti-inflammatory drugs, antibiotics, chemotherapeutic agents, or radiological contrast materials). The glomeruli, tubules, interstitial tissues, and renal pelvis may be affected.
