Kidney stones occur when salts within the urine form a solid crystal.
A kidney stone is a hard, crystalline mineral material formed inside the kidney or urinary tract. Kidney stones are a common cause of blood within the urine (hematuria) and often severe pain in the abdomen, flank, or groin. Kidney stones are occasionally called renal calculi.
Kidneys are the filtering organ in our body that remove waste materials in the blood, which are then excreted in the body in the form of urine. Stones or stone-like hard masses develop, when minerals and acids present within the urine crystallize and accumulate within the kidneys.
If the stones are small, they are able to easily pass through the urinary tract, after which out of the body without causing discomfort. But, large stones could possibly get stuck inside the urinary tract, and produce a host of symptoms, including severe pain. It’s been observed that the occurrence of kidney stones is less in women than men.
Kidney Stones Symptoms
Kidney stones occur when salts within the urine form a solid crystal. These stones can block the flow of urine and cause infection, kidney damage or perhaps kidney failure. Most kidney stones can be treated without surgery. Many women with kidney stones don’t have any symptoms. However, some people do get symptoms, which might include:
This symptom occurs when a kidney stone gets stuck within the ureter, and blocks the passage of urine either partially or completely. Together with pain, one can also experience a burning sensation while attempting to pass urine.
Nausea and Vomiting
Passing a kidney stone can be quite painful, due to which one can get nausea and vomiting. Likewise, existence of an infection and fever, and also the associated weakness can produce such symptoms.
Bloody or Cloudy Urine
Existence of blood in urine (hematuria) can indicate an infection caused by kidney stones. Blood may also be present, when the stone becomes lodged within the urinary tract, especially inside the ureter and cuts the liner of the ureter. Some people having kidney stones can pass cloudy urine using a foul smell, which can be a symptom of kidney infection and/or a blocked ureter.
Frequent Urge to Urinate
Like painful urination, this symptom can also be produced when the stone gets lodged within the ureter, and pushes against the wall from the ureter.
As mentioned above, kidney stones can cause infection sometimes, in which case, one can experience fever too. The fever can be combined with chills. Infection usually results when a kidney stone blocks the passage of urine, or causes irritation within the urinary tract.
Lower Back Pain
The pain caused by kidney stones could be mild or severe, depending on their size. The little kidney stones can produce mild cramping pain within the lower abdomen and the back, which many women may confuse using the pain that they experience during menstruation.
