Methods for evaluatiy the excreted function of the kidneys

The urinary system plays an important role for the body, in which the kidneys are the part that perform the task of filtering and excreting urine. There are many methods used to assess kidney function such as blood tests, urine tests, ultrasounds, CT scans, biopics. In it, to evaluate the excreted function of the kidneys will be based on a number of specific criteria in tests and techniques.

1. How important is the function of the kidneys?

In the structure of the human body there are two kidneys, located on the sides of the spine, under the rib cage at the lowest position. In each kidney is the million nephron – the functional unit of the kidneys. A nephron is a filtration unit of small blood vessels, also known as codocons, attached to the renal tubular. The blood into the kidney is filtered, the rest of the fluid goes along the tube, the same chemicals and water are added or removed from the liquid, to filter according to the needs of the body. The final product of the kidneys is urine, which is excreted by the body.

Thus, it can be seen that, filtering and excreting waste products, excess fluid out of the body are two functions of the kidneys. In addition to these two important functions, the kidneys perform other tasks such as alkaline-acid balance, the production of hormones that control blood pressure, control calcium conversion and stimulate red blood cell production.

2. Methods for evaluatiy the excreted function of the kidneys

2.1 Blood tests that evaluate the excreted function of the kidneys

  • Blood ure test: Ure is a product decomposed from proteins in foods consumed daily. Through the causity, the ure is filtered and excreted by urine. Through the blood ure index, the test allows to assess the excreted function of the kidneys and monitor for kidney diseases such as renal failure, tubular inflammation, angulitis, kidney stones, ureter stones,…
  • Blood creatinine test: Creatinine is the waste of muscle movement. Through urine, creatinine is also excreted in the urine. Depending on the age, weight of the body, the concentration of creatinine in the blood of each person will be different. When the creatinine index is high, that is, renal function is in disorder.

2.2 Urine tests that evaluate the excreted function of the kidneys

Urine electrolysis: When a protein is excreted in the urine, it may be a warning sign that the function of the kidneys is having problems due to kidney damage or increased levels of immunoglobulin in the blood. Protein classification in the urine electrolysis test allows to distinguish acute glomatitis or ureteral proteins caused by damaged renal tubular.

2.3 Photo tests that evaluate the excreted function of the kidneys

Renal X-ray with intravenous drugs is a method that allows to evaluate the excreted function of the kidneys. This method is usually applied in surgical treatment for patients with urolithiasis (performed before surgery), urolithiasis causes blockage and fluid retention in the ureter, increases post-kidney pressure and inhibits the excretion function of the kidneys. Besides, the excretion function of the kidneys is also impaired or completely lost in the final stages of renal tuberculosis or tumors in the kidneys.

3. Other methods of evaluatiy the excreted function of the kidneys

In addition to the methods of testing to assess renal function from blood, urine, diagnostic imaging, there are many methods to assess the ability of the kidneys to excrete and re-absorb, namely the renal tubular:

  • High pissing test: Patients are given a certain amount of water, about 600ml of water in a period of 4 hours. Normally, the amount of urine excreted is greater than the amount of water drunk, the proportion varies depending on the time. This solution is applied to detect kidney failure, causing the function of the kidneys to decrease, the patient has less urine out and has a proportion that is not changed or reduced.
  • Dilution test: Patients are required to starve and perform bladder clearing to remove all urine. Then, for about 30 minutes, the person is given 1.5 liters of water. Every 30 minutes, the person is given urine once to quantities and urine proportions. The test is carried out for 4 consecutive hours. The normal result is that the total amount of urine taken in 4 hours is greater than or equal to the amount of water drunk, the lowest proportion value is less than 1,002. This solution is also applied to detect kidney failure, causing the function of the kidneys to decrease, with the result that the amount of urine excreted is less than the amount of water drunk, the lowest weight value is greater than 1,002. However, this solution is limited to contraining in case the patient is completely impaired or edema.

  • Treatment of insymation: Patients are required to be inactive for 24 hours, do not drink water more than 500ml, only eat dry. Take urine about every 3 hours for dosing and proportions, taken in 24 hours. The normal result is that the amount of urine excreted reaches about 300 – 700ml of water, the proportion is between 1,025 – 1,035, the highest value must reach 1,025. This solution is also applied to detect kidney failure, causing kidney function to decrease when the weight price reaches just under 1,025. However, this solution depends on many factors and limitations.
  • PSP method: Patients are required to drink about 200ml of water twice, the drinking time is 30 minutes apart. 15 minutes after drinking water, proceed to take the urine of the patient, intravenously inject psp solution with a concentration of 6% a 1ml amount. After that, conduct urine bladder clearing 2 times, the first is 15 minutes after injection. The second time is 70 minutes after the injection. Urine is taken and put in 2 different cups, which alkaline properties. The normal result is that the PSP concentration measured after 15 minutes is at least 15%, the minimum 70 minutes is 55%. This method is also applied to detect renal failure, causing the function of the kidneys to decrease when the concentration of PSP measured in the excreted urine decreases, if the decrease of 1⁄2, i.e. the blood ure concentration increases. This is caused by obstruction of the urinary tract, which causes a slow duration of PSP excreted or a PSP that is not excreted. This method has the advantage of being less toxic and easy to implement, so it is often applied because it is easy to implement and less toxic.
  • Methylene blue method: Intravenously 1ml methylene blue solution 1/120. After that, conduct a bladder scan so that it is possible to observe the time each side of the kidney excretes methylene blue outwards. If bladder screening cannot be performed, it can be replaced by a bladder clearance technique for urine. Urine excreted in blue is methylene blue. The normal result is that the urine is blue after 30 minutes, after about the 3rd or 4th hour, the urine is the greenest and runs out of green after 48 hours. This solution is applied to detect a number of conditions that affect kidney function such as interstitial renal inflammation that causes long-term slow excretion, sub-acute renal inflammation that causes a lot of excretion and early, stagnant renal tanks that cause slow excretion time or may become completely clogged. However, 2 PSP and methylene blue methods may give incorrect results, since some conditions such as prostate gland, ureteral kidney stones, … will interfere with the excreting of substances if the dosage is not correct.

There are many methods for evaluating the excreted function of the kidneys such as blood tests, urine tests, X-rays and some others. Depending on the condition, the doctor will prescribe the appropriate assessment method.
