Kidney stones can be extremely painful. They form within the kidneys where they remain dormant and without causing pain. However, if a stone becomes mobile, it leaves the kidney and enters the ureter, the tube between the kidney and the bladder. This causes intense pain and often also vomiting. We don’t know why some people seem more at risk to form kidney stones, but the risk is made worse by dehydration and the concentration of the urine.
Small stones, under a few millimeters in size, can be expected to pass spontaneously. However this may take several days. Larger stones can become impacted. Impacted stones may require intervention by a urologist to remove them.
Diagnosis of kidney stones is usually accomplished by CT scanning. We can identify the size and location of the stone. Treatment consists of pain and nausea control and consultation of a urologist as indicated.
