Causes of Recurrent Kidney Stones

Recurrent Kidney Stones   Causes in men & women

The bean shaped organs called kidneys perform a couple of important functions, necessary to maintain good health.  They separate toxins, mineral wastes, and other unwanted substances (including fluids) from the blood with the help of the excretory units called nephrons.  These waste materials land up in the blood stream after the metabolism of food particles consumed by the individual.  After the filtering process, most of the dissolved substances and water is put back into the blood stream, and only certain amounts of water and charged subatomic particles are used in the secretion of urine.

So urine is composed of water, electrolytes, certain mineral elements, and other substances, but mostly of water.  Since the initiation of urine is from the kidneys, stone formation or to be more specific, crystal formation also beings at the kidneys.  When urine becomes highly concentrated, meaning increased numbers of mineral salts and less of water molecules, the mineral elements begin to crystallize and develop into kidney stones.

It has been noted that once an individual develops and passes a kidney stone, there is a relatively high possibility for stones to return in them time after time.  There are several factors contributing to stone development, and gaining knowledge about them may help in reducing the risk of experiencing recurrent kidney stones.

Individuals, who have had the displeasure of passing a kidney stone at a very young age, are more likely to pass more kidney stones during their lifetime.  Men are more likely to experience recurrent episodes of kidney stone development than women.  After the age of 40, the risk of developing kidney stones in them increases.  This can be attributed to the fact that the prostate gland, which is a part of the male reproductive system, has a tendency to enlarge as their body ages.  This gland is situated just below the urinary bladder and about the base of the urethra.  Thus, an enlargement will compress these organs of the urinary system, obstructing urine flow.  When there is a constant obstruction, more urine beings to accumulate within and stored urine promotes the crystallization of mineral salts and their further development into kidney stones.Unless this gland condition is treated and brought under control, the person will experience recurrent stone formation in their urinary tract.


Dehydration, even mild depletion of body fluids, but lasting for a long duration will eventually lead to kidney stones.  As stated above, water molecules assists in dissolving mineral elements of urine.  A person who drinks only minimal amounts of water on a daily basis will insufficiently meet the body’s water requirements and produce low urine volumes constantly.  Concentrated urine produced continually increases the person’s risk of developing recurrent kidney stones.

Frequent episodes of urinary tract infections also lead to recurrent kidney stones.  A couple of kidney stone types are also known as infection stones.  This means that their formation is encouraged more when an infection develops in the urinary tract.  This is more common among the female population for the bacteria causing the infection are more likely to enter their urinary system after sexual interactions.

Inherited metabolic disorders or other hereditary diseases that malfunctions the metabolic process of certain mineral salts will increase their count in urine as well as the frequency of kidney stones.
