First & Foremost

Urinary stones or calculi are concretions formed within the urinary tract by the crystallization of one or more substances normally found within the urine. These calculi can be found anywhere within the urinary tract from the kidneys, ureters, and bladder. Most often these stones are formed within the kidney and travel down the ureter towards the bladder causing a sudden sharp intense pain along the flank which radiates towards the groin. Kidney stone pain is often intermittent and crescendo in nature and associated with nausea and vomiting. This complex of symptoms is commonly referred to as renal colic. Kidney stone patients often note difficulty finding a comfortable position and therefore move continuously to try to "shake off" the pain.


The symptoms of renal colic alone are often highly suggestive of passage of a kidney stone. A patient may complain of severe flank or abdominal pain radiating to the lower abdomen or groin area. The pain of renal colic is described often as sharp, severe, intermittent, and occurring with abrupt onset. Nausea and vomiting often accompany these symptoms. If infection and obstruction is present, the patient may experience fevers and chills. Stones can, however, present without any symptoms. Frequent urination or the constant urge to urinate are symptoms that are commonly seen as the stone is passing from the ureter into the bladder.
