Stage of renal failure

2016-12-24 14:09
Renal failure is divided into three treatment periods, doctors will choose the most appropriate treatment according to different stages. Symptoms of renal failure are not the same, but many patients often do not realize.
1 little urine period. This period generally lasted 7~14 days, the longer the duration, the worse the prognosis of patients. This period due to the kidney is more serious damage, glomerular filtration rate decreased sharply, in a short time urine volume significantly reduced, various uremic toxins in vivo accumulation cause systemic systemic poisoning symptoms. Its severity depends on the rate of development of primary disease and patient's disease and whether there is high catabolism. Because immune function decline easily concurrent infection, serious and even threaten the lives of patients.
More than 2 urine. From oliguria into polyuria, this period usually lasts 1~3 weeks. More urine at the start of the glomerular filtration rate has not been restored, the stage of the treatment of renal tubular concentration function is poor, blood urea, creatinine and potassium can also continue to increase, the complications still prone to water electrolyte and acid-base imbalance and concurrent infection of acute renal failure, and therefore can not be careless.
3 recovery period. Renal tubular cell regeneration, glomerular filtration rate gradually recovered to pre onset level, blood urea nitrogen and creatinine decreased to normal range in patients with acute renal failure. Because the reabsorption of renal tubular epithelial cells often need a few months to recover, so it should be used with caution drug damage to kidney. A few serious cases eventually left varying degrees of renal structural and functional defects.
