Symptoms of renal failure in different stages

1. Renal failure is a great harm to human kidney renal failure, if treated properly, it will cause uremia, and even threaten the safety of themselves, understand the symptoms of renal failure in each stage, early treatment of renal failure is urgent. Next is a brief introduction of each stage of renal failure symptoms.
The onset of symptoms of renal failure
Patients with this disease often experience some known causes of ATN, such as hypotension, ischemia, sepsis, and nephrotoxicity. But no obvious renal parenchymal damage has been observed. Acute renal failure is preventable at this stage. However, with the obvious damage of renal tubular epithelium, GFR suddenly declined. The clinical symptoms of renal failure became obvious, and then entered the maintenance period.
The maintenance of symptoms of renal failure
Oliguria phase. Typical for 7-14 days, but can also be as short as a few days, up to 4-6 weeks. Glomerular rate remained low. Many patients develop oliguria ("40Oml/d"). But some patients do not have oliguria or urine volume above 400ml/d, which is called non oliguria acute renal failure. The condition is mild and the prognosis is better. However, no matter whether the urine volume decreases or not, with the decline of renal function, a series of symptoms of renal failure can appear in clinic. Infection is another common and serious complication of acute renal failure. In the course of acute renal failure or in the course of disease development, multiple organ failure can be combined, and the mortality rate can be as high as 70%.
The period of recovery of symptoms of renal failure
The symptoms of renal failure are renal tubular cell regeneration, repair, and restoration of renal tubule integrity. The glomerular filtration rate gradually returns to normal or near normal range. Oliguria type begins to appear diuresis, can have polyuria performance, daily amount of urine can amount to 3000-5000ml, or more. Usually last 1-3 weeks and then back to normal. Compared with glomerular filtration rate, the recovery of glomerular epithelial cell function (solute and water reabsorption) is relatively delayed and usually takes months to recover. A small number of patients may eventually leave varying degrees of structural and functional defects in the kidney.
The above is a brief introduction to the stage of renal failure symptoms, I hope to help you, if you have other questions, you can consult our online doctor or give us a message, we will reply to you as soon as possible.
