Pyelonephritis

Kidney infection

It is usually one kidney that develops the infection and it is more common in women than men

About

Most kidney infections develop as a complication of cystitis (bladder infection). Bacteria causing cystitis can travel up to infect a kidney. The bacteria are usually those which live in the bowel. Some kidney infections develop without a bladder infection. This is due to other problems in the kidney such as stones or an abnormality of the kidney.

Need to know

  • Symptoms of pyelonephritis icon plus

    Symptoms of pyelonephritis may include: - Pain in the side of the abdomen or back area over the kidney (loin pain) - High temperature (38 degrees centigrade), with shivering - Feeling nausous, vomiting and or diarrhoea - Blood in your urine (haematuria) - Pain on urinating and frequency - Urinary tract infections - Urinary frequency or urgency
  • Screening and diagnosis icon plus

    Your consultant or GP will ask about your symptoms and recent medical history. They will carry out a urine test to see if you have a urinary tract infection (UTI). If you are a man with a confirmed infection, your consultant will refer you straight to our urology department for further investigation. Urological investigations include: - MRI scan - DMSA - Contrast enhanced computer demography (CECT) If your consultant is concerned that you may have an obstruction (such as a kidney stone that is stuck in the ureter) or a structural abnormality in your urinary system, other tests may be ordered, such as a CT (computed tomography) scan or ultrasound.
  • Potential treatment options icon plus

    Treatment options include: - Increasing fluid intake to prevent dehydration - Antibiotics, to clear the infection - Non-steroidal anti-inflammatory painkillers. These will not be recommended unless absolutely necessary as they can cause an increased risk of problems with the kidney function during a kidney infection
