1. Beginning of this period patients often suffer from some of ATN plateau known cause, such as hypotension, ischemia, sepsis and renal toxins. But has not yet generated significant kidney damage nature. Acute renal failure at this stage is prevention. But with significant renal tubular epithelial damage, GFR suddenly reduced, the clinical manifestations of acute renal failure syndrome becomes significant, then enter the maintenance period.
2, also known as oliguria maintenance period. Model is 7-14 days, but can be as short as a few days to 4-6 weeks long. Glomerular rate remained at a low level. Many patients may exhibit oliguria (40Oml / d). However, some patients may be no oliguria, urine output in 400ml / d or more, known as non-oliguric acute renal failure, its most mild physical condition, the prognosis is good. However, regardless of whether or not to cut the amount of urine, renal function and reduced the ham, the clinical manifestations can be a series of high-performance creatinine uremia.
3, recovery of renal tubular cell regeneration, restoration, tubular complete recovery. Glomerular filtration rate is a little bit back to normal or near-normal range. Oliguric patient began to exhibit diuretic, urine can show how daily urine output up 3000-5000ml, or more. Daily life continued 1-3 weeks, and then again back to normal. And glomerular filtration rate comparison, glomerular epithelial cell function (reabsorption of solute and water) recovery relative delay, often take several months after recovery. Some patients may ultimately left with varying degrees of renal structural and functional defects.
Symptoms related to kidney failure patients on three friends to explain here, in this prompt renal failure patients and patient families, as well as to kidney highly valued, active treatment, can not be too impulsive, be patient adhere to treatment, until fully recovered.
