Symptoms of Calcium Phosphate Kidney Stones

Calcium Phosphate Kidney Stones  – Signs & Symptoms

Kidney stones generally pass out of the system on their own, at least the small sized ones.  In a typical manner kidney stones exit the body along with the passage of urine.  However, when the stones grow to a sufficient size, it can cause a blockade anywhere in the urinary tract, but mostly in the ureters.  In a common scenario, kidney stones form when the urine is dense with crystal forming substances and less in water, which actually aids in dissolving them.

Stones formed in the kidneys are of various types, and the less common known type is the calcium phosphate kidney stone.  Unlike most kidney stones that develop when the urine is highly acidic, formation of calcium phosphate stone is stimulated in more alkaline urine.  This alkalinity often is induced by the presence of bacteria causing urinary tract infections.  And when calcium phosphate mineral salts are more in alkaline urine, it is often due to certain disease conditions like renal tubular acidosis.  Some calcium oxalate stones may also contain phosphates in minimal amounts.

Kidney Stone Symptoms  Blood in urine may become visible to the sufferer when the stone is expelled out of the body with some difficulty or because of their rough edges scraping harshly against the linings of the urinary tract.  This may emit some amount of blood that is discharged along with urine.

The pain observed while passing a kidney stone can be very extreme in nature.  Pain begins around the flank and back regions; when the stone moves out of the kidneys.  As they enter the ureters, the lower abdomen and groin regions are inflicted with pain.  In a situation where the pain leaves a crippling effect, sometimes sufferers may begin to experience nauseousness or even discharge stomach contents via the throat and mouth.


Now since usually calcium phosphate stones are associated with urinary tract infections, symptoms of this may also be observed which are a burning sensation while urinating, foul smelling urine, high body temperatures, and shivers.  Also, when a blockage arises anywhere in the urinary tract from a kidney stone, the infection can become more serious.  The person will feel the urge to urinate often, but not much urine is expelled due to the obstruction.  Since urine also contains a certain amount of germs, stored urine containing these microorganisms will add to the existing problem.

Normal urine will generally have a mild smell and is of the color of straw.  A slightly stronger smell is normal to emit from urine passed first thing in the morning.  Sleeping for straight eight hours in a warm bed can cause the body to get dehydrated, and the by-products of certain foods consumed the night before retiring to bed all contribute to the distinctive smell in the urine discharged at sunrise.  But when an infection originates in the urinary tract, the urine will appear cloudy and emit a foul smelling odor.

In an attempt to fight the infection, the body will increase its temperature and speed up body reactions to resolve the infection.  To a certain extent, high body temperatures will inhibit the growth of these infection causing microorganisms.
