Background
Urine is produced by blood passing through kidney and being filtered and reabsorbed, and the produced urine is mainly used for removing in-vivo metabolites and redundant water. The urine volume discharged by normal adults in 24 hours is 1000-2000 ml, and more than 2500 ml is polyuria, which is often caused by excessive water intake by the body or reduced water reabsorption by renal tubules (urine concentration disorder). Urine volume less than 500ml is oliguria, less than 100 ml is anuresis, and is mainly related to intake of too little water, loss of too much water (such as heavy bleeding, severe burns, diarrhea and the like) and reduction of glomerular disease filtration rate, and when urine is generated and discharged too little, metabolites in vivo accumulate, and uremia is generated. The urine specific gravity refers to the weight ratio of the same volume of urine to pure water at the same temperature. Healthy adults have a urine specific gravity of 1.015 to 1.025, and if the urine specific gravity is often lower than 1.010, it is mostly caused by impaired renal function, renal concentration and loss of dilution function.
