Symptoms of Calcium Oxalate Kidney Stones

Calcium Oxalate Kidney Stones – Signs &  Symptoms

Kidneys in the human body function as filtering organs.  They separate waste material from the blood and deposit it in the urine secreted by kidneys for their easy elimination out of the body.  Human urine is composed more of water and may be ten percent of mineral matters, complex proteins and pigments.  Mineral compounds and salt material can get crystallized when the urine produced stimulate crystal formation.Pain in Kidneys

Production of concentrated urine means less of water content and more of dissoluble substances.  But since there is no sufficient amount of water available to dissolve these mineral materials, they get retained back.  Concentrated urine is produced when water intake is less, which also means less urine volume, and infrequent urination.  Hence, the urinary bladder holds urine for a long period of time, and crystallization easily occurs in stored urine.

When urinary calcium and oxalate salts are in increased numbers, crystals begin to take form by the union of calcium and oxalate compounds and further develop into calcium oxalate kidney stone.  In fact, calcium oxalate renal stone is the type frequently encountered by kidney stone sufferers.  Excess urinary calcium excretion can arise from a high calcium diet or due to disordered metabolism of calcium.  Certain calcium supplement forms are also known to cause excess calcium in urine.  Likewise, oxalates can enter the urine from following a high oxalate diet or from any medical conditions that increase urinary oxalate excretion.

In most kidney stone sufferers though crystallization of calcium oxalates occur, they go unnoticed because they are microscopically small.  They get eliminated out of the system on their own and without any outward signs or symptoms.  It is when they get adhered to the urinary tract walls and begin to grow in size that problem arises.  The size of the stone can become large enough to disrupt normal flow of urine by causing blocks in the urinary tract.  When it comes to this stage, extreme degrees of pain will be observed.

Pain usually occurs in the abdominal area, the sides of the flank area and can travel to groin regions.  The back may also be inflicted by pain.  Sometimes the pain can be so incredibly intense that it can cause the person to pass out.  Vomiting or a nauseous feeling may also be observed by those writhing in pain.  Pain is usually from the stone moving and travelling down the urinary tract to be expelled out of the body.  The urinary tract contains openings and ducts that may be too narrow for a moderate sized stone to pass through easily.  When they do get blocked anywhere in the urinary tract, the muscles are contracting continuously in an attempt to force the stone out from where it is lodged.  This action is the cause of extreme pain.

Pain during urination may also be evident, and this is because of a stone blockage occurring anywhere around the urethral opening.  Or the pain may be from the stone successfully passing out of the system, but is large enough to brush against the lining of the urinary ducts to cause the painful burning sensation.
