What examination should oliguria do?

summary

For the first time, we often need to do a variety of tests on the kidney, such as urine routine, urine protein quantitative, urine red blood cell count, urine micro protein, etc. Tests are performed to determine if there is a lesion or damage to the kidney. Today, Zhongkang physical examination is going to talk about a very important clinical examination routine urine examination. So, what examination should oliguria do?

What examination should oliguria do?

The color of normal urine is mainly determined by urinary pigment. The normal urine output of human body is almost the same every day, and the amount of urine determines the color of urine. Normal urine color is colorless or light yellow. Drugs, food, blood and pigment can affect the color of urine.

Tubular type is a kind of columnar substance formed by proteinuria condensing in renal tubule. Normal urine only contains a very small amount of albumin, generally no tube type, or occasionally a small amount of transparent tube type. Once a tube type appears in the urine, it indicates at least one nephron status, which is an important signal of kidney disease.

In the process of examination, the indicators of white blood cells, red blood cells and small round epithelial cells in urine are of great significance for the diagnosis of the disease. Normal urine contains a small amount of white blood cells. If it contains a large number of white blood cells, it indicates that there are purulent diseases in the urinary tract, such as urethritis, cystitis, pyelonephritis, etc; Red blood cells can be seen occasionally in normal urine. If a large number of red blood cells appear, it is caused by renal hemorrhage or urinary tract hemorrhage; In normal urine, a small amount of adipose small round epithelial cells can be occasionally seen. If the number of epithelial cells increases, it indicates that the patient has glomerular kidney. If the number of small round epithelial cells increases, it indicates that the renal tubule has pathological changes.

matters needing attention

The specific gravity of normal urine is in the range of 1.015-1.025, and that of infants will be slightly lower. Urine specific gravity is affected by age, water intake and sweating. As the urine specific gravity is related to the concentration function of the kidney, we can judge whether the renal function is normal by this index. Normal urine contains a small amount of glucose, ranging from 0.1 to 0.3 g, the maximum can not exceed 0.9 g, the test should be negative; If you have diabetes, renal diabetes, or hyperthyroidism, the test will be positive.
