Kidney stones : Symptoms

Very small kidney stones are unlikely to cause many symptoms. They may even go undetected and pass out painlessly when you pee.

Larger kidney stones can cause symptoms, including:

  • pain in the side of your tummy (abdomen) or groin – men may have pain in their testicles
  • a high temperature
  • feeling sweaty
  • severe pain that comes and goes
  • feeling sick or vomiting
  • blood in your urine
  • urine infection

Blocked ureter and kidney infection

A kidney stone that blocks the ureter, the tube that connects your kidney to your bladder, can cause a kidney infection.

This is because waste products are unable to pass the blockage, which may cause a build-up of bacteria.

The symptoms of a kidney infection are similar to symptoms of kidney stones, but may also include:

  • a high temperature
  • chills and shivering
  • feeling very weak or tired
  • diarrhoea
  • cloudy and bad-smelling urine
