Male urine red

Male friends must pay attention if they find that their urine is red when going to the toilet, because this may be caused by symptoms of hematuria. In this case, you must go to the hospital for a detailed urethral examination to find out the real reason for this situation. Most of the time, it is caused by the high hemoglobin index in your body.

1. Red urine may be hematuria, hemoglobinuria, or myoglobinuria.

When the amount of blood in urine exceeds 1 ml per liter, the urine may be brown-red like meat washing water, which is called gross hematuria. Uroporphyrin is present in the urine of porphyria, which may turn red after being left. Urine may turn pink after taking phenolphthalein. Urine may turn red after taking mercurochrome, phenytoin, anticholesterol drugs, dithiamethoxam, daunorubicin, doxorubicin and other drugs as well as certain food colorings. Reddish-brown urine may also be seen after taking drugs such as deferoxamine and metronidazole.

2. Yellow-brown urine is seen in jaundice and bilirubinuria, and can also be seen in taking drugs such as rhubarb and vitamin B2. It can also be seen in urine with a large amount of uric acid precipitation, and can appear in children's urine in cold weather.

3. Orange-yellow urine can be seen in dehydration or high fever, or excessive urinary bile. Taking rifampicin can make the urine orange-red, and taking senna can make the urine yellow-red.

4. Dark brown, soy sauce or brown urine is seen in acidic hematuria, acidic hemoglobinuria, crepe oil, salicylic acid, benzyl alcohol or bisphenol A poisoning. Taking drugs such as levodopa, triamterene, methyldopa, etc. can make the urine brown and black.

5. Green urine is seen after taking methylene blue and indigo carmine. Bilirubin urine can also turn green when it is left for too long and oxidized to bilirubin. Taking methoxythiazine can make urine tea green.

6. Milky white urine is seen in chyluria, purulent urine, and urine containing phosphate precipitation.

7. Blue urine is seen in urine containing methylene blue and urea blue.

8. Almost colorless urine is seen in diseases such as diabetes, diabetes insipidus, renal atrophy, and polycystic kidney disease.

Gross hematuria refers to blood or meat-washing water-like urine that can be seen with the naked eye. Urine containing a certain amount of red blood cells is called hematuria. Red blood cells that can only be found under a microscope are called "microscopic hematuria". Generally, less than 1 ml of blood in 1000 ml of urine cannot be identified by the naked eye and is only slightly turbid. Urine containing 2 ml of blood is slightly reddish, and 4 ml of blood is obviously bloody. If there are more than 3 red blood cells in each high-power field of view of centrifuged urine, it is pathologically significant.
