Kidney Failure

What causes kidney failure? (Continued)

Renal causes of kidney failure (damage directly to the kidney itself) include:

Sepsis: The body's immune system is overwhelmed from infection and causes inflammation and shutdown of the kidneys. This usually does not occur with simple urinary tract infections.

Medications: Some medications are toxic to the kidney including:

  • Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Advil, Motrin, and others), and naproxen (Aleve, Naprosyn)
  • Antibiotics like aminoglycosides gentamicin (Garamycin), tobramycin
  • lithium (Eskalith, Lithobid)
  • Iodine-containing medications such as those injected for radiology dye studies

Rhabdomyolysis: This is a situation in which there is significant muscle breakdown in the body, and the damaged muscle fibers clog the filtering system of the kidneys. Massive muscle injury may occur because of trauma, crush injuries, and burns. Some medications used to treat highcholesterol may causerhabdomyolysis.

Multiple myeloma

Acute glomerulonephritis or inflammation of the glomeruli, the filtering system of the kidneys. Many diseases can cause this inflammation including:

Hemolytic uremic syndrome: This condition results from abnormal destruction of red blood cells. It most often occurs in children after certain infections, but also may be caused by medications, pregnancy, or can occur for unknown reasons.

Post renal causes of kidney failure (post=after + renal= kidney) are due to factors that affect outflow of the urine:

  • Obstruction of the bladder or the ureters can cause back pressure because the kidneys continue to produce urine, but the obstruction acts like a dam, and urine backs up into the kidneys. When the pressure increases high enough, the kidneys are damaged and shut down.
  • Prostatic hypertrophy or prostate cancer may block the urethra and prevents the bladder from emptying.
  • Tumors in the abdomen that surround and obstruct the ureters.
  • Kidney stones. Usually, kidney stones affect only one kidney and do not cause kidney failure. However, if there is only one kidney present, a kidney stone may cause the remaining kidney to fail.

Chronic renal failure develops over months and years. The most common causes of chronic renal failure are related to:

Less common causes of chronic renal failure include:

  • Polycystic kidney disease
  • Reflux nephropathy (damage caused by urine backflow from the bladder into the ureters and kidney)
  • Nephrotic syndrome
  • Alport's disease
  • Interstitial nephritis
  • Kidney stones
  • Prostate disease Continue Reading
