Stages of Renal Failure in Women

Generally, renal failure in women can be divided into 3 stages, which go as follows:
The first stage is the beginning stage. In this stage, some patients have suffered from damage from acute tubular necrosis, such as low blood pressure, insufficiency of blood, there are not so obvious damage in the renal parenchyma. So in this stage, acute renal failure can be prevented. With more obvious damage in renal tubular epithelial cells, GFR will decline suddenly and there will be more symptoms such as acute renal failure. Patients come into maintaining stage.
2. Patients with renal failure come into maintaining stage, which can also be called oliguria stage, which generally lasts for 7 days. But sometimes, it lasts for as long as 4 to 6 weeks. The renal glomerular filtration rate keeps at a low level, so patients may have oliguria, which means that the urine amount is less than 400ml every day. Some patients can also have urine which is more than 400ml. Their condition is usually not so bad and their prognosis is usually good. However, with the disease developing, symptoms will appear more if not treated well. Infection is a severe complication for acute renal failure.
The third stage is recovery stage. In this stage, the renal tubular cells regenerate, recover, and the renal glomerular filtration rate increases even to normal range. Patients who have oliguria begin to have more urine. The amount of urine is as much as 3000ml, which lasts for 1 to 3 weeks. Compared with the recovery of renal glomerular filtration rate, the recovery of renal glomerular epithelial cells’ function is slow, which may last for several months sometimes. A few patients may have different degree of renal structure insufficiency and functional insufficiency.
