mechanisms cause of urinary tract calculi

As for name “of the calculus” being different, as for the disease it is same

Name changes at the position where it has the calculus (redspot in upper figure).From above in order, upper kidney calculus, ureter calculus and bladder stone

Many of the urine road calculus in the kidney, is possible, the “kidney calculus”.This getting off in the ureter, those where it remains and/or those which have been plugged the “bladder stone”, getting off the “ureter calculus” and those which are in the bladder in the urethra, remain and/or have been plugged are called the “urethra calculus”.

In addition, the kidney calculus and the ureter calculus the “upper urine road calculus”, the bladder stone and the urethra calculus are called the “lower part urine road calculus”, but presently the upper urine road calculus has occupied 9 tenths or more of calculus.Name changes depending upon the place where the calculus has remained, but the disease itself is the same.

It differs in dietary life and regional difference, cause of the urine road calculus

Cause of the calculus differs depending upon the component.The difference of ratio of the upper urine road calculus and the lower part urine road calculus, is thought that there is dietary life.As for cause of the upper urine road calculus there are the European-American conversions of dietary life, as for the lower part urine road calculus they become easy us be able to assume that taking too much of grain and urine road infection and urination obstacle joins.

Recently in addition, as for cause of the urine road calculus, it understood that simply is not just dietary life.For example, also influence of the female sex hormone which has calculus obstruction action is said.

the incidence in japan is a large regional differences (differences in geology) there are, it has been said in the area ratio of the calcium contained in drinking water is high and a higher incidence.

further, that may have a family who had a disease of the urinary tract such as urinary tract stones tend to be, we have found that genetic factors are also involved.

different types of urinary calculi in the component

professional is a little, components of the stones can be in the body is not the same. the name of the calculus is different for different components.

calcium oxalate stone
was associated with calcium oxalate has been discharged in the urine abnormally a lot for some reason. in stone is the most common component.

disease hyperoxaluria (a high concentration of oxalic acid in urine) , hypercalciuria will be a direct impact on stone formation or.

uric acid stone
an increase in blood uric acid level known as the cause of gout, uric acid is excreted in the urine a lot. uric acid stones as the core that uric acid stone is. and uric acid but soluble in alkaline, there are easy-to-nature ‘s acidic precipitation. so, this stone can be easier and become acidic urine.

it should be noted, you have the choice of drug for gout. the drug is administered in order to lower the level of uric acid in the blood2there are, 1one thing to suppress the production of uric acid in the body, more1one is intended to promote the excretion of uric acid in the urine of. uric acid concentration in the blood decreases, but the medicine of the latter, for uric acid concentration in urine is increased, urinary tract calculi can be easier.

cystine stone
this stone can be by congenital abnormalities of amino acid metabolism. cystine, lysine, that ornithine3of the two amino acid, cystine is precipitated in the urine. in the same way as uric acid stones, makes it easier to become acidic urine and precipitation.

magnesium ammonium phosphate stones
due to the urinary tract infection, is possible by the components in the urine is precipitated. by bacterial infection, when the state will cause a urinary stone is easy to precipitate the component. this is called infection stones stones like this.

obstruction of urinary stones that are caused by

stagnant urine in the kidney due to a failure always pass through the urinary tract, there are stones in the urine can by crystalline component is precipitated. hydronephrosis to say, if the kidney is swollen because of the failure of passage of urine from the kidney to the bladder.

because the state of the kidneys in urine is always stagnant, it tends to be a lot of stone material, causing the precipitation.

occur in the bladder, stone to grow

stones from the kidney to the bladder came down after a while remained, many are naturally excreted. but, if there is always residual urine in the bladder in obstruction of the lower urinary tract, beginning with benign prostatic hypertrophy, may they grow in a small bladder stones difficult to get out.

on the other hand, there may be a stone to precipitate the various components of residual urine in the urinary passage of urine associated with the failure.

foreign body in the bladder stones can be in
the case of bladder stones, there is also a stone that they can put foreign matter from the urethra rarely becomes the nucleus. for example, you may also put a catheter through the urethra in medical practice to become the nucleus.

if there is something in the bladder foreign body, create a stone to precipitate calcium and other various materials it as the core. this is due to the nature of physiological bladder, the stone will always attached also to develop a material no matter how difficult to adhere. why does not quite achieve the development of artificial bladder is for this reason.
