Clinical manifestations of renal failure?

  Click:

1, the starting period of this period patients often suffer some of the known causes of ATN, such as hypotension, ischemia, sepsis and renal toxins. Yet no obvious renal parenchymal damage. At this stage of acute renal failure is preventable. However, with the apparent renal tubular epithelial injury, GFR a sudden drop in the clinical manifestations of acute renal failure syndrome became apparent, then enter the maintenance phase.

2, maintaining a view also known as oliguria period. Typical for 7-14 days, but can also be as short as a few days, for as long as 4-6 weeks. Glomerular rate remained low. Many patients, there may be oliguria (<40Oml / d). However, some patients can not oliguria, urine output in 400ml / d above, known as non-oliguric acute renal failure, its most mild disease, the prognosis is good. However, regardless of whether the reduction in urine output, with renal dysfunction, the clinical manifestations may appear a series of uremia.

Infection is acute renal failure, another common and serious complications. In patients with acute renal failure at the same time or in the disease process of development can also combine multiple organ failure, the patient mortality rate as high as 70%.

3, recovery of renal tubular cell regeneration, repair, restore tubular integrity. Glomerular filtration rate gradually returns to normal or near normal range. Oliguria began to appear in patients with diuretic, urine can have the performance of daily urine output of up to 3000-5000ml, or more. Usually last 1-3 weeks, and then again back to normal. And glomerular filtration rate, glomerular epithelial cell function (solute and water reabsorption) relative delay in the recovery, and often take a few months after the resumption. A small number of patients could eventually be left by varying degrees of renal structural and functional defects.

Renal failure diet Note:

When renal dysfunction, the toxins can not be excreted in urine will accumulate in the blood causing symptoms of poisoning (ie, uremia), the body can lead to an excessive number of hydrogen, sodium and potassium ions.

Control diet, for patients with chronic renal failure is a basic treatment modalities can reduce the production of toxins in urine, the body will help maintain a minimum nutritional requirements and electrolyte balance, but this plan is to have the patients themselves and their families, efforts to overcome a challenge, because often need to give up some to meet their fill of food.
