Daily diuresis is the most important indicator of kidney function

In medicine, diuretic is the excretion of urine over a certain period of time. Accordingly, daily diuresis - the release of urine during the day. The volume of diuresis in healthy people ranged from 500 to 2000 ml. Daily diuresis allows you to judge the intensity of the kidneys throughout the day. Its number depends on several internal and external factors. The volume of daily diuresis is affected by the amount of fluid drunk, the intensity of sweat secretion, air temperature, and kidney function. Daily diuresis less than 500 ml is called oliguria, less than 100 ml - oligoanuria, and complete absence of urine - anuria.

Oliguria - a decrease in daily diuresis

Oliguria can be physiological and pathological. A physiological decrease in the volume of urine is observed when there is a restriction of fluid intake, in the hot season, when a significant amount of fluid is lost with sweat. Pathological oliguria happens when fluid is lost from the body in other ways, bypassing the kidneys. This can be with repeated vomiting, diarrhea, profuse release of sweat, as well as with the rapid formation of swelling. The symptom of oliguria is observed in chronic renal failure. Oligoanuria is a transitional condition between oliguria and anuria, it happens with the pathology of the urinary system.

Anuria

Anuria always indicates a severe kidney damage. It occurs with the development of acute kidney failure, chronic kidney failure in the severe stage, as well as obstruction of the urinary tract with stone or squeezing the tumor. The development of anuria requires the provision of emergency care, otherwise the patient dies from uremia. Emergency care consists in the blood purification of the blood by hemodialysis, that is, connecting the patient to the "artificial kidney" apparatus.

Polyuria

The term polyuria is called an increase in the daily volume of urine above two liters. Like oliguria, polyuria can be physiological, that is, it is observed in practically healthy people, and pathological. Physiological polyuria happens when you consume large amounts of liquid, juicy fruit. For example, often the appearance of polyuria is observed in the season of ripe watermelons. Polyuria is one of the symptoms detected in the initial stage of chronic kidney failure or in the recovery stage in chronic failure. The appearance of polyuria is observed in the appointment of diuretics and the rapid convergence of edema.

The value of daily diuresis in pregnancy

Daily diuresis in pregnancy is a particularly important indicator. With the help of this study, you can monitor the correct course of pregnancy, at early stages to identify the development of possible complications. Daily diuresis of pregnant women is monitored for the early detection of gestosis, the development of which provokes the pathology of the urinary system in pregnant women until the development of acute kidney failure.

Diuretic diuretic technique

Determination of daily diuresis - one of the most common and simple methods of investigation, is prescribed for patients with chronic heart pathology, as well as for acute and chronic diseases of the urinary system. To determine the daily diuresis within one day, the urine is offered to the patient to collect in one graduated capacity, with the help of which the volume of urine allocated for the day is determined.

Diuretic diuresis is closely related to the water balance, which is determined by comparing the amount of fluid drunk and the excreted urine. When counting the amount of liquid consumed, juicy fruits and vegetables and liquid injected intravenously are also taken into account.
