Urine plays a role in the field of nephropathy

Feb 26, 2018

Normal people will urinate four to six times a day, the total urine volume between 1000-2000ml. Urine more during the day, but due to the decline in blood flow at night, intake of water is also less, under normal circumstances the number of toilets at night 2 times.

Urine plays a role in the field of nephropathy

Many elderly people and children sometimes start their night-time meetings for more physical reasons, but young adults rarely start their night with particular attention to daily urination and oliguria. Abnormal urine in the performance of the performance of nocturia, no urine, oliguria, polyuria and other symptoms, but for the "volume" of the word control, ordinary people more vague understanding. Now give you these specific quantitative indicators, but also hope you pay attention, okay?

Clinical daily urine output is greater than 2500ml of polyuria, nocturnal urine output accounts for more than half of all urine volume is increased nocturia. If young people do not often stay up all night, but there is always the phenomenon of increased nocturnal, it should be wary of kidney problems. Because of chronic nephritis, renal insufficiency, polycystic kidney disease will cause damage to the renal tubules, resulting in decreased urinary concentration, will lead to an imbalance between day and night urine output, nocturnal increase.

If the urine volume is less than 400ml, is oliguria; less than 100ml, is no urine. Such as sudden acute glomerulonephritis, it will show hypertonic volume of urine, the formation of less original urine; chronic renal failure, glomerular filtration rate will reduce oliguria, which is characterized by low-permeability Oliguria, urine output increased after the reduction; acute rejection after renal transplantation, can also lead to decreased glomerular filtration rate caused by oliguria. In the end of kidney disease, when the condition is very serious, there will be no urine.

In addition, there is a common urinary abnormalities are urine redness, this time someone would think that hematuria, of course, will think of kidney disease, but the fact is not entirely true! Red urine and hematuria can not be completely equated, once found urine turns red, you have to pass the urine test to determine whether hematuria. Only urine test found that red blood cells greater than 3 / HP, can be identified as hematuria, which is related to kidney disease.

Such as kidney stones, nephritis and other diseases can lead to the emergence of hematuria, and the elderly once the gross hematuria, we must guard against urinary tract tumors. Once the above situation occurs, quickly to the hospital renal internal medicine examination, medical consultation, with the doctor as soon as possible diagnosis and treatment.
