尿量是观察肾脏功能的镜子,急性肾功能衰竭(ARF)时,描述尿量的名词在24小时尿量少于100毫升为无尿,100～400毫升为少尿,超过400毫升为多尿,又分相对性多尿(400～2000毫升)和绝对性多尿(超过2000毫升),ARF时,相对性多尿称为非少尿性急性肾功能衰竭(NOARF)。本文就NOARF研究的历史和现状做一综述。 Urine volume is a mirror for the observation of renal function, acute renal failure (ARF), the term describing the amount of urine in 24 hours urine output of less than 100 ml for anuria, 100 to 400 ml for oliguria, more than 400 ml for polyuria , Sub-relative polyuria (400 ~ 2000 ml) and absolute polyuria (more than 2000 ml), ARF, the relative polyuria as non-oliguric acute renal failure (NOARF). This article reviews the history and current status of NOARF research.
