Acute kidney injury is a clinical syndrome caused by a variety of etiologic factors, resulting in a rapid decline in renal function within a short period of time, manifested as a decline in glomerular filtration rate, and accompanied by abnormalities in blood urea nitrogen, blood creatinine and so on.
The main diagnostic criteria of acute kidney injury are as follows: glomerular filtration rate decreases in a short period of time, and blood creatinine clearance increases ≥26.5 umol/L within 48 hours; blood creatinine clearance is confirmed or presumed to increase ≥50% from the basal value within 7 days; patients show symptoms of decreased urine output or anuria, or urine output is ＜0.5 ml/Kg/h and lasts for ≥6 hours.
According to the primary etiology, the phenomenon of acute onset and the accompanying symptoms such as oliguria, it is generally not difficult to diagnose. If you suspect acute kidney injury, you should go to the hospital in time to get a clear diagnosis from the doctor and actively cooperate with the doctor to avoid delaying the condition.
