Stages of chronic renal failure






    creatinine content and glomerular filtration rate
    symptomatic classification and localization of nephrons

large amount of damage to the classification of chronic renal failure is not necessary for the doctor to choose the most convenient for themselves, but in order to maximize the diagnosis has been described.

The process can be called chronic only if the duration of the exacerbation period and the improvement of the patient's condition is at least three months. Therefore, an analysis for the glomerular filtration rate is not considered reliable
on creatinine and the glomerular filtration rate of the phase

Renal of creatinine disease:

    1 step. The creatinine level is higher than normal. Reaches 440 mmol / l. Absence of serious morphological and functional damage to organ complexes.
    second stage. The creatinine level rises to 880.
    3 stage. Until 1330.
    4th stage. More than 1331 mmol / l.

important in the diagnosis to evaluate the glomerular filtration rate:

    In the initial phase of activity it decreases by half.
    A further drop in filtration speed is not more than 30%. However, this is not an improvement in conditions. This indicates a compensatory phase.
    During the terminal phase, the reduction in glomerular filtration rate is not greater than 20%.

Stages of renal failure

The basis of this classification is the ability of the kidneys to regenerate. The onset of CRF occurs when the ineffectiveness is 1/5 of the giutaglomerare apparatus. Despite the renal parenchyma it is capable of high regeneration. However, if 4/5 tissues are dead, compensatory mechanisms are not possible. Therefore, the quality of the renal glomeruli and their functional activity can be assessed on the basis of glomerular filtration rate.
Regardless of the phase of chronic, compensated or uncompensated renal failure, the body accumulates nitrogenous products. It is possible to find creatinine and urea. Their level is directly proportional to the type of inverse absorption disturbance in the renal glomeruli.

Furthermore, classification invented and proven based on the age of the child. It is based on the level of creatinine and the factor of age. Age is divided into two periods: from two years to twelve and from thirteen to eighteen. It is very efficient, as renal tissue changes with age and its growth depends on the speed of development of the child and the maturation of the speed of the tissues. Purely anatomically, the kidney becomes a reduced copy of an adult at the age of 2 years. But physiologically it is only formed at 18 years.

The level of creatinine is also different.It is minimal in the second week of life (about 6 thousand ml / min) .The first week is relatively high - 41 thousand. At 8 weeks and 13 years the concentration is not very different. The difference is 10 thousand.
symptomatic classification and location of damage

nephrons addition, isolated classification for nephron damage pins:

    The partial - is characterized by local or generalized sclerosis. THE'
    total - when a constant internal environmental disturbance develops caused by the abnormal hardening of nephrons, especially juxtaglomerular.
    Terminals - when large pieces of cloth does not work, compensation mechanisms are impossible, glomerular filtration rate is not greater than 15 ml / min.

hemodialysis
Hemodialysis - the possibility of a patient with end stage renal failure in the extension of the experts

life from Europe have created a classification, which combines both glomerular filtration rate, and symptoms. This is a sort of combined classification.

first stage. It is characterized by a small amount of albumin in the urine and damage to the glomerular apparatus, the filtration rate is about 300 ml / min.

second stage .The speed is not more than 90, a small amount of albumin in the urine, and also the sclerosis of the nephrons.

third stage of .The speed does not exceed 60 ml / min.

4th phase of filtration speed does not exceed 30

5th stage (terminal) .15 ml / min.
Stages of renal failure

The most convenient classification is based on symptoms of chronic renal failure.

The initial phase is characterized by:

    a rare increase in blood pressure;
    at night invocations to the toilet;
    reduced filtration rate;
    mild degree anemia.

conservative:

    nocturnal urination becomes more vyzhrat;
    fast fatigue;
    weight loss;
    syndromes of anemia and high blood pressure.

If the severity of the disease and its long duration, dialysis is possible.
Kidney failure
Unfortunately, renal failure - an irreversible phase process

Terminal: Directions
hemodialysis for chronic hemodialysis in

    renal failure decreased urine output; The glomerular filtration rate
    it is less than 20 milliliters per minute;
    appetite decreases;
    feeling sick;
    oral oral mucosa;
    thirst; Convulsions
    ;
    left ventricular failure;
    reduces visual clarity;
    skin coloring in yellow and appearance of bleeding;
    nose bleeding;
    pain in the spine

of progression of chronic renal failure is directly dependent on the occurrence of complications. The most frequent complications are hypertension, beriberi, anemia. Rare include metabolic syndrome, urinary tract infection. Weak immunity and the development of pneumonia, glomerulonephritis.

hemodialysis at the end of the second stage is necessary, as it is possible the development of multiple organ failure, and even a kidney transplant will not be able to save the situation.

Therefore, it is important to accurately determine the time of hospitalization with the diagnosis and to treat the disease correctly. The classification of chronic renal failure must necessarily be in the doctor's head and its use and diagnosis must not cause difficulties.
