What causes urinary tract infection?

Speaking of urinary tract infection, many friends think that only if you do not pay attention to hygiene during sexual life can you get this disease. In fact, this is not the case. There are many causes of urinary tract infection. Hygienic sex life is only one of the causes of the disease. Decreased resistance and ascending infection can also lead to the occurrence of urinary tract infection. In order to let everyone know about urinary tract infection in detail, this article will make a detailed analysis of the causes of urinary tract infection.

1: Lymphatic infection: The lymphatic vessels of the lower abdomen and pelvic organs have many communicating branches with the lymphatic vessels around the kidneys, and there are also lymphatic vessels communicating between the ascending colon and the right kidney. Bacteria can also infect the kidneys through the lymphatic vessels during pelvic organ inflammation, appendicitis, and colitis. This route of infection is even rarer, and there is currently debate about whether it even exists.

2: Direct infection: When there is trauma or infection in organs adjacent to the kidney, bacteria can directly invade the kidney and cause infection. However, this situation is very rare clinically.

3: Ascending infection: Most urinary sensations are caused by ascending infection. Under normal circumstances, there are bacteria parasitic in the urethral opening and its surroundings, but they generally do not cause infection. When the body's resistance is reduced or the urethral mucosa is slightly damaged, or when the bacteria are highly virulent and have a strong ability to adhere to the urethral mucosa and ascend, they can easily invade the bladder and kidneys and cause infection.

4: Hematogenous infection: Hematogenous infection is more common in newborns, or hematogenous renal infection in patients with Staphylococcus aureus sepsis.

5: Ascending infection: Urinary sensation is caused by ascending infection. When the body's resistance is reduced or the urethral mucosa is slightly damaged, or when the bacteria are highly virulent and have a strong ability to adhere to the urethral mucosa and ascend, they can easily invade the bladder and kidneys and cause infection.

6: Because men are busy with work, they rarely pay attention to personal hygiene, especially local hygiene, which allows bacteria to invade the male reproductive organs. Under the long-term stimulation of inflammation, male friends suffer from urinary tract infections.

The above-mentioned causes are all the causes of urinary tract infection. Only by avoiding these situations can you avoid urinary tract infection. In addition, male friends are reminded not to hold urine for too long when working or playing games. Because holding urine for a long time will not only damage your kidneys, but also cause certain damage to the urinary system, which will also lead to symptoms of urinary tract infection.
