Description
Technical field
The present invention relates to the diagnostic fields of stone in urinary system, filter out observation tube more particularly to a kind of urinary crystal.
Background technique
Stone in urinary system is one of most common urological diseases and one of the intractable disease that doctor is faced,
Disease incidence is in 5-10%.Archaeologist proves that having stone in urinary system before 7000 exists, and seeing Egyptian wood is
With her.The disease incidence 10-20% in China some areas, stone in urinary system can also induce renal impairment and failure, serious to endanger
Do harm to the health and quality of life of the people.
The formation of stone in urinary system has external cause and internal cause, and external cause mainly has natural environment (geographical location) or social environment
(diet), internal cause are mainly inherent cause, metabolic disorder and urinary system self problem (as blocked or infecting).With internal cause or outside
Because of uncertain morbidity, the generation of calculus also needs certain condition and has a process and pathogenesis.It is falling ill at present
There are a series of theories in mechanism, each theory is to illustrate this problem from an angle, so not reaching an agreement also.So
And root is returned to reveal the inside story, numerous lithiasises destroy the stabilising system of urine because causing the component ratio in urine to be changed,
Causing the ingredient supersaturation of long calculus to be precipitated is micro-crystallization, and the non-crystalline material cohesion in microcrystal and urine becomes calculus, because
This, the exception of urinary crystal occurs being an important indicator for judging calculus risk.It is clinically also consistent to generally acknowledge, when abnormal in urine
When there is more microcrystal, the morbidity of stone in urinary system is prompted.Calculus is easily formed when crystalline particle >=35 μm.Work as urine
Crystallization frequency of occurrences in urina sanguinis is more than 50%, and recurrence rate is 87.5% in calculus 1-3.Understand urinary crystal ingredient, we
Its Forming Mechanism can be utilized, corresponding prevention and treatment measure is taken to calculus.According to the difference of crystalline component, uropoiesis tying
Stone can be divided mainly into: calcinm oxalate calculus (about 30%-40%), calcium oxalate-calcium phosphate combination calculus (about 30%-40%), uric acid class knot
Stone (about 20%-30%), guanite (about 4%) and cystine class calculus (about 1%).
Crystal can cause the birefringent of polarised light and interference, rotate analyzer in polarised light visual field, it is found that crystal goes out
Existing light and shade alternately change and color stripes, clearly with the histocyte difference of surrounding, convenient for identifying.
Currently, it since the crystallization content in urine is very rare, to the inspection of urinary crystal in clinical urine test, first will need
Particulate matter in urine, is focused on the bottom of test tube by urine centrifugation, after discarding the most urines in top, then suction foot urine
It is put under microscope and observes again after sediment.But the operation of this process is fine, and the foreign matter in air can be made to enter in access panel, existed
A possibility that polluting sample.Physical impairment is avoided in order to prevent calculus early, while it is negative to reduce personal and country medical treatment
Load needs early stage to filter out urinary crystal at home, and can facilitate observation.Therefore, a kind of easily operated urine is researched and developed
Crystallization filters out observation tube and is very important.
Summary of the invention
