Renal failure is characterized by pathological changes in glomerular filtration, tubular reabsorption of urea, disturbances in urinary rhythm, changes in renal blood flow and its hemodynamics, and endothelial dysfunction. It may be the only cause of azotemia, a condition in which the level of urea and creatinine in the blood increases.
In case of chronic renal failure with a slow progression, the patient experiences diabetes, which occurs throughout his life. In women, chronic renal failure usually develops more slowly than in men. In children, acute renal failure can occur with oligoanuric and hyperhydration forms. But children more often develop the polyuric form of acute renal failure.
CRF (chronic renal failure) occurs with chronic damage to the kidney parenchyma. AKI (acute renal failure) - occurs acutely, develops quickly and is clinically not similar to chronic renal failure
