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.

严重的肾损伤可肾小球滤过率，即单位时间内肾脏过滤的血液量，这可导致少尿高血症。

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.

血液滤过减少，造成尿量减少，称为少尿，即尿量异常，同时尿酐滤出减少，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.

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