Green urine

Introduction Green urine: normal urine color is light yellow, transparent, no precipitation turbidity. The urinary tract that has just been solved has a special aroma of grass, and after a long time, it has an ammonia smell due to decomposition. However, under some abnormal conditions, such as diseases or drugs, the color of the urine will change, and the urine will be green and green urine.

Cause

It is seen when there is a growth of Pseudomonas aeruginosa in the urine, or when the bilirubin urine is left for too long and is oxidized into biliverdin. Light green urine: seen after taking a lot of anti-inflammatory drugs. Dark green urine: the reason is the same as blue urine. Can be seen in cholera, typhus, and primary hypercalcemia, vitamin D poisoning. However, the urine of this color is mostly related to medication, not caused by disease. Such as taking the diuretic ampicillin, injection of methylene blue injection or taking methylene blue, Leica red, creosote, salicylic acid can appear. Stopping the drug will disappear.

Urine microscopy: Urine white blood cell microscopy analysis method, the corresponding relationship between visual field average and qualitative results is positive 10 ~ 20 (+), 21 ~ 50 (++), > 50 (+ + +), full cloth Field of view (++++).

Urine routine: urine is pale green or dark green, turbid, and may precipitate.

Differential diagnosis

Black urine: black urine is relatively rare, often occurs in patients with acute intravascular hemolysis, such as falciparum malaria, medically known as black urine fever, is one of the most serious complications of falciparum malaria. The patient's plasma contains a large amount of free oxygen, hemoglobin and oxyhemoglobin, which are dark red or black in urine. A small number of patients who take levodopa, cresol, benzoquinone, etc., will also cause black urine, which will disappear after stopping the drug. According to foreign reports, patients with paroxysmal myoglobinuria will also explode brown-black urine after exercise, accompanied by muscle weakness, which can gradually develop into dysentery. In addition, black urine can also be seen in phenol poisoning, black tumor, and urinary acidosis.

Brown urine (like soy sauce color): can be seen in acute nephritis, acute jaundice hepatitis, kidney crush injury, extensive burns, hemolytic anemia, mistype blood transfusion, even after intense exercise, urine can also be like soy sauce color. Sometimes the urine is brown after sleep, which is characteristic of paroxysmal nocturnal hemoglobinuria. If this kind of urination occurs after eating green broad beans, you should be alert to faba disease. The patient's red blood cells lack a substance called phosphoglucose dehydrogenase, which is somewhat heritable. Therefore, when eating broad beans, brown urine will appear, and fatigue, dizziness, nausea, skin, and yellow eyes should be sent to the hospital for treatment in case of any accident. Colorless urine - may be a signal of diabetes, chronic interstitial nephritis, diabetes insipidus, if not drinking too much, should pay attention to identification.

White urine - white urine is common in purulent urine, chyluria and salt urine.

Purulent urine is caused by severe urinary purulent infection, and the urine is milky white. Purulent urine is common in pyelonephritis, cystitis, renal abscess, urethritis, or severe renal tuberculosis. Chyluria is one of the main symptoms of filariasis, white urine like milk. Because the intestinal absorption of the chyle (the liquid after the saponification of fat) can not be drained from the normal lymphatics to the blood circulation, it can only flow back into the lymphatics of the urinary system, causing the lymphatic pressure in the urinary system to increase, varicose and rupture. The chyle is spilled into the urine, and chyluria appears. Chyluria is generally paroxysmal. When there are red blood cells in the chyluria, it is called chyluria. Microfilaments (ie, young silkworms) can sometimes be found in the blood and urine of patients with chyluria.

Salt urine - more common children in winter are common, urination is rice soup-like, mostly contains a large amount of phosphate or uric acid in the original, easy to precipitate after placement, such as the urination will be cleared immediately after heating in the bottle. Salt urine is a normal physiological phenomenon. Can be cured without drugs, the key is to drink more boiled water. Yellow urine - refers to urine yellow or dark yellow. The reasons are:

1 When eating carrots, taking riboflavin, , , rhubarb and other Chinese and Western medicines, the urine may turn yellow. Once you stop taking it, it will disappear and you don't have to worry about it. Common fever or vomiting and diarrhea patients are discharged with sweat or feces, urine will be concentrated and reduced, and urine pigments will not change, so the color of urine will appear very yellow.

2 Another type of urinary yellow like strong tea is not due to the above reasons, but the liver or sac has lesions. It turns out that there are usually two paths for bile to go out: one out of the urine and one out of the intestines. When the liver or gallbladder is sick, the path of bile to the intestine is cut off, it can only be discharged from the urine, and the urine is dark yellow due to the increase in bile content. In the early stages of hepatitis, jaundice has not yet appeared. We can often see the color of urination like strong tea, which is often a sign of hepatitis.

In addition, yellow turbid pyuria is a manifestation of urinary organ purulence. Blue urine - can be seen in cholera, typhus, and primary hypercalcemia, vitamin d poisoning. However, the urine of this color is mostly related to medication, not caused by disease. Such as taking the diuretic ampicillin, injection of methylene blue injection or taking methylene blue, Leica red, creosote, salicylic acid can appear. Stopping the drug will disappear. This blue urine caused by taking the medicine is a normal phenomenon and need not be considered.

Red urine - the urine color turns red, mostly red blood cells in the urine, medically called hematuria. The cause of hematuria is very complicated. There are hundreds of diseases that can cause hematuria. It is not so easy to diagnose correctly.

1 If hematuria is accompanied by nosebleeds, bleeding gums, and skin bleeding, this may be a systemic bleeding disease, such as thrombocytopenia, allergic purpura, hemophilia, and even leukemia. Urine is only a manifestation of systemic bleeding. .

2 If hematuria is accompanied by fever, joint swelling and pain, skin damage, and multiple organ damage, it may be a connective tissue disease (such as systemic lupus erythematosus, nodular arteritis, etc.).

3 If hematuria with hypertension, edema, proteinuria, mostly glomerulonephritis.

4 If hematuria is accompanied by lumbar and abdominal pain and discomfort, urgency, frequent urination, and dysuria are mostly urinary tract infections or tuberculosis.

5 If hematuria is accompanied by lumbar pain or abdominal cramps on one side, the possibility of kidney and ureteral stones is the greatest, especially the pain in the bed is uneasy, mostly ureteral stones.

6 If hematuria is accompanied by poor urination, laborious, and urinary discharge, in elderly men, most of them are enlarged prostate. In middle-aged men, urethral stricture, urethral stones or bladder tumors should be considered.

People over the age of 50 have visible or significant microscopic hematuria, both male and female, suggesting that there is a lesion in the urinary system. In particular, the sudden occurrence of painless hematuria, most of which is caused by the tumor eroding the urine discharge tube causing ulceration, a slight delay will permanently lose the effective treatment opportunity.
