Chronic renal failure is diagnosed in children with urinary organs, while maintaining them within 3-6 months of decline in glomerular filtration less than 20 ml \ min, an increase in serum creatinine and urea.
Over 50 diseases (glomerulonephritis, pyelonephritis, nephropathy, etc.) that manifest renal disease may end in chronic renal failure.
In contrast to acute renal failure for renal disease progression and irreversibility of the characteristic.
Chronic renal failure characterized by gradual development of weakness, pale skin, anorexia. BP usually normal initially, but subsequently increased. In poliuricheskoy stage chronic renal failure (daily urine is 2-3 l), which can take years, moderately pronounced increase of nitrogen, glomerular filtration of 20-30 ml \ min, the relative density of urine relative lower plasma density.
Urinary Syndrome weakly expressed in congenital nephropathies, may show varying degrees of proteinuria, hematuria, and leukocyturia in chronic renal failure as a consequence of glomerular and pyelonephritis. In oligoanuricheskoy stage, lasting 4.1 months., A sharp deterioration due to the addition of a hemorrhagic syndrome, cardiovascular collapse, resulting in incremental changes in metabolism.
The long life of children with chronic renal failure depends on its cause: patients with tubulointerstitial pathology are living longer (up to 12 years and over) than patients with glomerulopathy (2-8 years) without dialysis and kidney transplantation in the treatment.
Chronic renal failure is aimed at reducing giperazotemii. First, eliminate the cause and correcting violations resulting homeostatic (isotonic sodium, 5% solution of glucose). Corrective measure is to maintain a diet with limited protein. Spend as hemodialysis and renal transplantation.
