The human body is composed of various bodies, many of which are hollow anatomical structures, ie they have internal cavities. These are, e.g., bronchus, esophagus, intestine, blood vessels. This structure contributes to such a state as obturation, ie partial or complete blockage of the lumen of the body cavity. This may be due to illness or, conversely, an artificially caused to treat.
Root canal obturation
Artificial body cavity closure of the lumen is characteristic of such a sphere of medicine as dentistry. It is carried out in the dental fillings in the case of treatment of periodontitis or pulpit. Root canal obturation can be of two types: permanent and temporary. Implement it using special filling materials. This is considered to be the most rational use of gutta-percha, that is processed in a certain way latex. Typically, this material does not cause allergy, and its ability to expand when heated can accurately fill the necessary cavity. Gutta-percha is used in conjunction with pastes - Sillery.
Temporary obstruction of channels is made in cases where the formulation permanent seal can not be accomplished due to the presence of local inflammation. This may indicate pain with percussion or swelling in the area of the tooth. Obturation of the channels in this situation requires netverdeyuschih plastic material must, moreover, possess certain therapeutic qualities. Time, which is set on similar materials, ranging from several days to several months. After the disappearance of the symptoms of inflammation set a permanent seal.
Urinary tract obstruction
Narrowing of the urinary tract can occur at any age. The children most of all - a congenital abnormality. For adults, a characteristic acquired defects of the excretory system. Thus urinary tract obstruction is not in itself a disease, it only shows the manifestation of a disease in the body. Possible mechanical closing of the urinary tract, e.g., due to their blockage of stones or tumor. Also, quite often there are functional disorders. They result from inflammatory injury ureter or bladder and lead to a narrowing of the channels.
Regardless of the causes, excretory tract obstruction impairs their function and leads to the development of renal failure, acute or chronic.
The main symptoms of narrowing channels - the difficulty of outflow of urine and pain of varying intensity, the strength of which depends on the speed of onset of obstruction. The most excruciating pain caused stones stuck in the ureter. This raises the renal colic, requiring immediate medical attention.
If the obstruction of the urinary tract increases gradually, the pain may not be as pronounced or entirely absent. However, chronic disorder of urinary outflow, usually leads to irreversible changes in the kidneys. That is why you need as quickly as possible to eliminate not only directly for the normalization of the very obturation removing toxins from the body, but also the cause of its occurrence.
The presence of abdominal organs in the human body is, on the one hand, a kind of a risk factor, as evidenced by the possibility of obstruction and, consequently, dysfunction. On the other hand, the free inner space allows, if necessary, to compensate the pathological changes occurring in the body.
