Symptoms - Kidney stones

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:

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

Blocked ureter and kidney infection

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

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 like 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
