One of the main symptoms of kidney stones is reno-ureteral colic, or “renal colic”, a sudden pain somewhere in the area along the route of the ureter (from the flank/mid-back to the lower abdomen) that is usually caused by the irritation of the ureter (causing spasm) and/or obstruction blocking the flow of urine from the kidney to the bladder.[1]
Additional symptoms that people with kidney stones may experience include the following:[2]
- Burning sensation during urination
- Nausea and/or vomiting
- Changes in urine (presence of blood, cloudy, or foul-smelling)
Some people with kidney stones may have no symptoms at all.
