What causes pyelonephritis?

Pyelonephritis results from an infection, generally bacterial, of the kidneys. Oftentimes, this infection spreads from the urinary tract to the bladder and progresses to the kidneys. Left untreated, it can lead to permanent damage. In very serious cases, the infection can spread to the bloodstream (sepsis).

What are the risk factors for pyelonephritis?

A number of factors increase the risk of developing pyelonephritis. Not all people with risk factors will get pyelonephritis. Risk factors include:

  • Diabetes (chronic disease that affects your body’s ability to use sugar for energy)
  • Enlarged prostate
  • Fecal incontinence (inability to control stools)
  • Hospitalization
  • Immobility
  • Immunocompromised health status
  • Kidney stones
  • Narrow urethra
  • Older age
  • Pregnancy
  • Previous bout of pyelonephritis
  • Problems voiding the bladder
  • Recent urinary tract infection
  • Surgery
  • Urinary catheter

Reducing your risk of pyelonephritis

The best prevention for pyelonephritis is obtaining prompt treatment for any urinary tract infection. You may also be able to lower your risk of pyelonephritis by:

  • Avoiding alcohol and caffeine
  • Avoiding tight-fitting pants
  • Avoiding undergarments made from synthetic materials
  • Avoiding use of scented products around the genital area
  • Bathing the opening of the urethra thoroughly and regularly
  • Drinking cranberry juice (unless you have kidney stones)
  • Drinking plenty of fluids
  • Seeing your doctor to treat urinary tract infections
