summary

It may be related to autoimmune reaction and g-6-p dehydrogenase deficiency. It is characterized by sudden onset, chills, high fever, low back pain, soy sauce colored urine, painful urination, severe anemia, jaundice, proteinuria and tubular urine. The geographical distribution of the disease is consistent with that of falciparum malaria. It is rare in other areas except Southwest and coastal areas in China. And dietary reasons, urethritis, bladder inflammation, kidney stones and so on. Let's take a look at the following.

Why is urine black

First: it is suggested to check in time whether there is hematuria. Black urine is generally rare in clinic. It often occurs with acute vascular blood, such as falciparum malaria and other diseases. In addition, phenol poisoning, melanoma and urinary melanosis can also be seen. Therefore, you should go to a regular hospital as soon as possible!!

Second: you check the urine routine to determine whether proteinuria. If it is proteinuria, it needs timely treatment, because proteinuria is one of the risk factors of kidney disease

Third: black urine, also known as dark brown urine, often occurs in patients with acute intravascular hemolysis, such as patients with falciparum malaria, medically known as black urine heat, is one of the most serious complications of malignant diseases. It can also be seen in people who take Lysol by mistake and suffer from phenol poisoning. Because phenol is oxidized into hydroquinone and catechin in the body, it is excreted from urine, and the urine becomes black urine after standing for a moment

matters needing attention

Another example is the patient with melanoma. Due to the increase of melanin production in the body, the melanin in the blood is reduced to melanin by the liver. The melanin excreted from the urine becomes melanin after oxidation. After standing for a moment, the urine turns black
