Kidney Stones - Symptoms

What are the symptoms of kidney stones?

For some people, a kidney stone may just stay in a kidney and cause no symptoms. Other kidney stones may travel out of your body in your urine without you knowing anything about it. If symptoms do occur, they include:

  • Pain from a kidney. A stone that is stuck in a kidney may cause pain in the side of your abdomen (loin). This pain can be very severe and cause you to feel sweaty and be sick (vomit).
  • Renal colic:
    • This is a severe pain which is caused by a stone that passes into the tube (the ureter) draining urine from the kidney.
    • The stone becomes stuck. The ureter squeezes the stone towards the bladder, which causes intense pain in the side of your tummy (abdomen).
    • The pain caused by renal colic may last from a few minutes to a few hours. The pain comes in spasms and between these spasms there may be intervals of no pain or just a dull ache.
    • The pain may spread down into the lower abdomen or groin. You may sweat, feel sick or even vomit because the pain can be very bad.
  • Blood in your urine. You may see blood in your urine (the urine turns red). This is caused by a stone rubbing against the inside of your ureter.
  • Urine infection. Urine infections are more common in people with kidney stones. Urine infections may cause high temperature (fever), pain on passing urine (dysuria) and a need to pass urine more often.
