Abnormal urination From the surface, mainly includes urine volume abnormality, urine color abnormality and abnormal urination ; from the microscope, it can be found that urine composition is also abnormal. In terms of different kidney disease patients, the content of abnormal urination is different, and of course there are various reasons for abnormal urination.
1. Abnormal urine output: abnormal urine output includes polyuria, oliguria, anuria and excessive nocturia.
The urine output of a healthy person is 1000~2000 ml per day. If exceeds 2500 ml per day, it is called polyuria ; if the daily urine output is less than 400 ml , it is called oliguria ; if the daily urine output is less than 100 ml , it is called no urine ; if the amount of urine at night exceeds the urine during the day If the amount of urine in night exceeds 750 ml , it is called nocturnal increase .
Polyuria, oliguria, anuria, and nocturia are common symptoms of kidney disease. Of course, the abnormal performance of urine output in different nephropathy is also different .
For example, chronic interstitial nephritis often has polyuria, and is characterized by nocturia and ; and acute renal failure often has symptoms of oliguria or anuria.
Therefore, although kidney disease often has abnormal changes in urine output, it is not necessarily caused by kidney disease. A healthy person will urinate more if they drink too much water, and if they sweat too much after exercising, they will have oliguria, etc. These situations are normal physiological phenomena and should be distinguished.
2. The color of urine is abnormal: generally the color becomes darker, turbid and blood red.
The color of urine of patients with nephropathy often changes abnormally. If the color of urine turns blood red, it is called hematuria. The reason why the color of
urine changes abnormally,It is due to changes in the composition of urine . When acute nephritis occurs, red blood cells can appear in the urine of , and the urine becomes blood red . There are many kinds of components in that cause the color change of urine, such as protein , red blood cells, pus cells and other , these components will not appear in the urine of healthy people, only when kidney disease occurs, urine Changes in the composition can cause abnormal urine color.
3. Paraesthesia during urination: mainly including frequent urination, urgency and dysuria
Healthy people urinate 4 to 6 times during the day and 0 to 2 times after sleeping at night. If the number of urination increases significantly beyond the above range, it is called frequent urination . Urgency to urinate refers to the feeling of urinating as soon as the urge to urinate comes, and as soon as there is the urge to urinate, it can't wait, even wet underwear, but the amount of urine is not much. Painful urination refers to pain and burning in the urethra when urinating.
Healthy people do not feel pain when urinating, but in the case of certain kidney diseases, the patient will be very painful when urinating. These symptoms are all abnormal urination, and most of them occur in patients whose urinary tract is infected with and . The causes of these symptoms are mainly inflammatory stimuli, such as pyelonephritis, co-infection of kidney stones, cystitis, etc., which all cause symptoms of frequent urination, urgency, and dysuria.
4, abnormal composition of urine
The vast majority of patients with kidney disease will have abnormal composition of urine during urine routine examination. When kidney disease occurs, white blood cells , red blood cells may appear in the urine, and some components need chemical analysis to be identified, such as protein.
Urine routine examination is a reliable method to check and analyze abnormal urine composition, and it is also the most commonly used auxiliary examination for kidney disease patients.
