Complications of benign prostate enlargement

Benign prostate enlargement can sometimes lead to complications, such as a urinary tract infection or acute urinary retention.

Urinary tract infections

If you’re unable to empty your bladder properly, there’s a risk that bacteria in your urinary system won’t get flushed out and will spread through the urine to cause a urinary tract infection (UTI).

Symptoms of a UTI include:

  • cloudy, bloody or badsmelling urine
  • pain in your lower abdomen (tummy) 
  • nausea
  • vomiting
  • shaking and chills
  • a high temperature of 38C (100.4F) or above 

UTIs can be treated with antibiotics. A single UTI isn’t usually serious, but repeated UTIs can damage your kidneys and bladder. If you have a history of repeated UTIs, you may need to have surgery.

Acute urinary retention

Acute urinary retention (AUR) is the sudden inability to pass any urine. AUR should be treated as a medical emergency, because without prompt treatment urine may be passed back up into the kidneys, which can damage them.

Symptoms of AUR include:

  • the sudden inability to pass urine
  • severe lower abdominal pain
  • swelling of the bladder that you can feel with your hands.

How common is benign prostate enlargement?

Benign prostate enlargement is a condition associated with ageing and is common in men over 50 years of age.
