Now, acute kidney injury can cause a low glomerular filtration rate, which is the volume of blood filtered through the kidney over a period of time, and this can lead to oliguria and hyperkalemia.

严重的肾损伤降低肾小球率，即单位时间内肾脏的血液量，导致少尿和高血症。

With less blood being filtered, less urine is produced, called oliguria, abnormally low urine production, and less urea and creatinine get filtered out, so more stays in the blood, called azotemia, high levels of nitrogen-containing compounds in the blood.

血液少，造成尿量少，称为少尿，即尿量异常低，同时尿素和肌酐出少，转而遗留在血液中，即氮质血症：血液中含有大量的含氮化合物。

Early symptoms include oliguria and eosinophiluria, which is eosinophils in the urine, but also general symptoms like a fever and a rash.

早期症状包括少尿和嗜酸性尿，即尿液中存在嗜酸性粒细胞，但也有发烧和皮疹等一般症状。
