What is a urinary tract infection?

A urinary tract infection (UTI) is an infection of the urinary system and is usually caused by bacteria.

When a person has a UTI, they need to see a doctor as soon as possible. If left untreated, it can spread to the kidneys and make it very difficult to treat.

What are the signs and symptoms of a UTI?

Signs and symptoms of a UTI may include:

  • a burning feeling when passing urine
  • a feeling that the bladder is still full after going to the toilet
  • passing urine more often than normal
  • lower abdominal pain, especially when passing urine
  • pain in the lower back
  • bad smelling urine
  • urine that is cloudy, bloody or dark
  • chills
  • fever
  • different behaviour to normal (delirium).

Why might someone have a UTI?

Some people are at greater risk than others of developing a UTI. This includes:

  • women, because the urethra is short and the bacteria only needs to travel a short distance from the outside of the body to the bladder
  • people who have regular problems with bowel management
  • people with severe constipation or faecal impaction
  • people who use urinary catheters
  • people who wear continence pads that aren't changed quickly when they are soiled or wet
  • men with prostate problems, because an enlarged prostate gland can stop the bladder from emptying completely
  • women with a prolapse, because their bladder may not be able to empty completely
  • people taking medicines that can interfere with how the bladder works, e.g. some medicines used to treat incontinence and colds
  • people with damage to the bladder nerves, which means the person may not feel a full bladder. They may have problems emptying their bladder from conditions such as diabetes, multiple sclerosis, stroke, Parkinson's disease or a spinal cord injury.

How can UTIs be prevented?

Many people find they can avoid UTIs by:

  • drinking plenty of water and other fluids to flush the urinary system
  • washing the genital area regularly
  • changing continence pads quickly when soiled or wet
  • going to the toilet when they feel the need
  • avoiding bowel problems like constipation and diarrhoea
  • wiping from front to back after going to the toilet.

What further treatment might be needed?

They may need to visit a specialist doctor, such as a urogynaecologisturologist or renal physician. They may also want to look at the issue further by:

  • asking the person to keep a bladder or bowel diary. For more information, go to How to fill out a bladder diary or How to fill out a bowel diary.
  • doing urine and blood tests
  • examining men for prostate problems or women for pelvic organ prolapse
  • looking for other medical conditions that may be causing the UTI.

If the person you support has a spinal injury above T6, make sure you know the signs and symptoms of autonomic dysreflexia.
