怎么说是溶质性多尿呢？

Urinary solute excretion varies with diet [10, 11]. On a typical Western diet, daily excretion of sodium is -150 mmol, potassium 75 mmol, urea 400 mmol and other nonelectrolytes 50 mmol [11]. Excretion of the 900 mOsm of solute generated by this diet in a volume of 1.5 L would result in an average Uosm of 600 mOsm/kg. Excretion of >1400 mOsm of solute daily (>1 mOsm/h) is clear evidence of a major solute diuresis [11]. Typically, in a patient with a major solute diuresis, Uosm ranges from 300 to 500 mOsm/kg, CH2O is negative and Cosm >200 mL/h. In a patient with a water diuresis, Uosm is typically <150 mOsm/kg and CH2O is positive. Mixed solute and water diureses can be present (e.g. in a patient with diabetes insipidus treated with saline infusions) [12].

尿溶质排泄随饮食而变化。在典型的西方饮食中，钠的日排泄量约为150 mmol、钾约75 mmol、尿素约400 mmol，其他非电解质溶质约50 mmol。该西方饮食产生的900 mOsm溶质随1.5 L的尿量排出，平均Uosm为600 mOsm/kg。每天排泄溶质>1400 mOsm (>1 mOsm/h)是严重溶质性多尿的明显证据。在一个严重的溶质性多尿的典型病人，Uosm范围从300-500 mOsm/kg、CH2O阴性和Cosm >200 mL/h。在一个有水利尿的病人，典型的Uosm<150 mOsm/kg和CH2O是阳性。溶质和水的混合性多尿也可出现（例如，尿崩症患者用生理盐水输液治疗）。

理解的对吗？Uosm范围从300-500 mOsm/kg不是小于600 mOsm/kg吗？那就应该是小于1.5L 尿量，怎么说是溶质性多尿呢？

Uosm尿渗透浓度？
