Early symptoms of kidney failure women have?

In the early stages of kidney failure, usually without any symptoms to warn patients her kidney does not work. This is why regular urine and blood test is very important reason. Sometimes even if the patient feel good about yourself, but health examination result will show with some signs of kidney disease.
Women with kidney failure can be divided into three stages:
1, this period starting stage patients often suffer from some known ATN causes, such as low blood pressure, ischemia, septic disease and kidney toxins. But has not yet occurred obvious renal parenchymal damage. At this stage is acute renal failure can prevent. But with renal tubular epithelial pronounced damage, GFR suddenly drop, the clinical performance of acute renal failure syndrome becomes apparent, into the maintenance phase.
2, maintenance phase and say less urine period. The typical for seven to 14 days, but can also be short to a few days and as long as four to six weeks. Glomerular rate remains low. Many patients can appear less urine (< 40 Oml/d). But there are also some patients can be no less urine, urine output in 400 ml/d above, known as the less urine type, its illness most acute renal failure is lighter, prognosis is good. However, no matter whether to reduce the urine output, with renal impairment, and clinical all can appear a series of uremia performance.
The infection is acute kidney failure, another common and serious complications. In acute kidney failure, and at the same time or in the process of the development of the disease still can merge multiple organ dysfunction syndrome, patients can be as high as 70% mortality rate.
3, recovery is renal tubular cell regeneration, repair, renal tubular integrity recovery. Glomerular filtration rate gradually back to normal or close to the normal range. Less urine type patients began to appear diuresis, can have more urine performance, daily urine output can reach 3000-5000 ml, or more. Usually last 1-3 weeks, then return to normal. Compared with glomerular filtration rate, glomerular epithelial cells function (solute and water heavy absorption) the recovery of the relative delay, often need only a few months after recovery. A few patients can finally left different degrees of kidney structure and function defects.
