The color of urine in normal people is light yellow, when drinking less water or sweating more, the urine volume decreases urine concentration, the urine color becomes dark yellow. When drinking a lot of water, the urine volume increases, the urine dilutes and the urine color becomes lighter or even clear. Other colors of urine, you can compare according to the following chart.
I. Colorless urine
It may be a sign of diabetes, chronic interstitial nephritis, and urolithiasis, and should be identified if it is not due to drinking too much water.
Second, white urine
White urine is commonly found in purulent urine, celiac disease and salt urine.
Purulent urine is caused by severe urinary tract septic infection, and the urine is milky white. It is commonly seen in pyelonephritis, cystitis, renal abscess, urethritis, or severe renal tuberculosis.
Celiac disease is one of the main symptoms of filariasis, with urine as white as milk. The celiac fluid absorbed by the intestine flows backwards into the lymphatic vessels of the urinary system, causing an increase in the internal pressure of the lymphatic vessels, and the varices rupture causing the celiac fluid to overflow into the urine, and celiac disease occurs. Celiac disease is usually paroxysmal. When there are red blood cells in celiac urine, it is called celiac hematuria.
Salt urine occurs more often in children in winter, and the urine is rice-like, mostly because the original contains a large amount of phosphate or uric acid. Salt urine is a normal physiological phenomenon. It can be cured without medication, and the key is to drink more plain water.
Third, yellow urine
Refers to the urine is yellow or dark yellow. The causes are.
Eating carrots, taking riboflavin, dysentery, dysentery, methotrexate, rhubarb and other Chinese and Western medicines in the process, the urine can become yellow, once you stop taking, then disappear, no need to worry.
Another kind of urine yellow like strong tea, is the liver or rouge sac has a lesion. There are usually two paths for bile to drain outward: one from the urine and one from the intestines. When the liver or gallbladder is diseased, the path of bile to the intestines is cut off and it can only come out of the urine, and the urine is dark yellow due to the increased amount of bile. This is often a sign of hepatitis. In addition, yellow, cloudy pus urine is a sign of pus in the urinary organs.
Fourth, blue urine
It can be seen in cholera and typhus, as well as in people with primary hypercalcemia and vitamin D toxicity. However, this color of urine is mostly related to medication and not due to disease. It will disappear when the medication is stopped.
V. Green urine
It is seen when there is Pseudomonas aeruginosa breeding in the urine, or when bilirubin urine is left too long and oxidized to bilirubin.
Light green urine: seen after taking a lot of anti-inflammatory drugs.
Dark green urine: The cause is the same as blue urine.
Black urine: Black urine is relatively rare and often occurs in patients with acute intravascular hemolysis, such as patients with falciparum malaria, medically known as black urine fever, which is one of the most serious complications of falciparum malaria. This is one of the most serious complications of falciparum malaria. In such patients, there is a large amount of free oxygen, hemoglobin and oxyhemoglobin in the plasma, which is excreted in the urine and causes the urine to be dark red or black. In a few patients, levodopa, methylphenidate and phenylhydrazine may also cause black urine, which will disappear after stopping the drugs.
Brown urine (like the color of soy sauce): It can be seen in acute nephritis, acute jaundice hepatitis, kidney crush injury, large burns, hemolytic anemia, and even after strenuous exercise, the urine can resemble the color of soy sauce. Sometimes the urine is brownish after waking up from sleep, and that is characteristic of paroxysmal sleep hemoglobinuria. If this urine appears after eating green fava beans, we should be alert to fava bean disease, should be promptly sent to the hospital to rescue, to prevent untoward.
Sixth, white drops after urination
Some young male patients will find a milky white discharge from the urethra after urination. Because this symptom is accompanied by frequent urination, urethral irritation symptoms and lumbago, dizziness, insomnia, sexual dysfunction, impotence and other symptoms, most patients often mistake this phenomenon of white dripping after urination for the omission of semen, calling it the root of the disease “body deficit”, so that the burden of thought. In fact, the white drops after urination is not what semen leakage, but due to chronic prostatitis. The white secretion that flows out is prostatic fluid, not semen. The actual fact is that you will be able to take antibacterial and internal Chinese medicine to cure this disease.
Seven, red urine
The red color of urine is mostly due to the presence of red blood cells in the urine, which is medically known as hematuria. Hematuria can be classified as naked eye hematuria (visible to the naked eye) or microscopic hematuria (visible to the microscope), and the color of the urine is pink or red. Microscopic hematuria usually has no change in urine color.
If hematuria is accompanied by vague discomfort in the lower back and abdomen, urinary urgency, frequency, and painful urination, it is more likely to be urinary tract infection or tuberculosis.
If hematuria is accompanied by distending pain in the lower back or abdominal cramps on one side, kidney and ureteral stones are the most likely, especially if it is so painful that you toss and turn in bed, it is mostly ureteral stones.
If hematuria is accompanied by dyspareunia, straining, and dribbling discharge of urine, in older men, it is mostly prostatic hypertrophy, and in middle-aged men, urethral stricture, urethral stones or bladder tumor should be considered.
Risk factors for cancer should be noted when hematuria is present, and seeing blood in the urine has a strong association with cancer and other possible serious underlying diseases.
The occurrence of hematuria in the naked eye in people over the age of 50 is suggestive of a pathology of the urinary system in both men and women. In particular, the sudden onset of painless hematuria can be lost forever to effective treatment if one is slightly lax.
According to statistics, bladder tumor is one of the most common tumors in urology. In developed countries in Europe and America, the incidence of bladder tumor ranks second only to prostate cancer among male genitourinary tumors; in China, it takes the first place and has been increasing in recent years.
The disease is more common in middle-aged and elderly people over 50 years old, and more men than women. Whether bladder tumor can be diagnosed early is crucial to the patient’s prognosis, so how can bladder tumor be detected and diagnosed early?
In fact, this intermittent and painless hematuria is often a clear sign of bladder tumor. Bladder tumors account for almost 50% of patients with painless hematuria.
There are two characteristics of hematuria in bladder tumors: one is painlessness, which means that when hematuria occurs, the patient does not have any pain and other discomfort symptoms, which is medically known as painless hematuria. This is different from the hematuria caused by stones with kidney and ureteral pain, and also different from the hematuria caused by urinary tract infection with frequent, urgent and painful urination. However, if tumor necrosis, ulceration and combined infection, bladder irritation symptoms such as urinary frequency, urinary urgency and urinary pain may occur. Secondly, it is intermittent, that is, hematuria appears intermittently and can be stopped or reduced by itself, and the interval between two hematuria can be several days or months, or even half a year, which can easily cause the illusion that hematuria has been “cured” or “improved” and mistakenly believe that the disease disappears without further examination in time. Therefore, once hematuria appears, active and timely examination should be taken to ensure early diagnosis.
Reminder: middle-aged and elderly people over 40 years old have always been healthy, once the inexplicable solution of bloody urine, not painful, painless hematuria, should think of the possibility of urinary tract tumors, and the first thing to be alerted is bladder tumors. We should go to hospital for examination in time to achieve early detection and early treatment.
