Finally, if those nitrogen-containing compounds aren't being filtered out, more stays in the blood, which causes azotemia.

最终，如果那些含氮化合物没有滤出，更多会留在血液中，导致氮质血症。

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，即尿量异常低，同时尿素和肌酐滤出减少，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。
