What causes urinary tract infection?

Urinary tract infection is caused by bacteria, viruses and fungi. In daily life, it is also a kind of urinary tract infection caused by the middle and front. There are more female patients. Clinically, it is mainly treated with some other types of antibiotics. It is mainly some urinary tract infections in the bladder. The common routes of pathogens are mainly some urinary tract infections caused by fungi, bacteria and parasites. In ascending infection, bacterial infection, lymphocyte infection and direct infection are also very critical.

Symptomatic treatment can be given, and the treatment of the pathogen is also very critical. Patients should be encouraged to drink more water and at least some patients should be given infusions. Some patients can take some Chinese medicine or other types of medicines in dosage forms. .

(1) 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 toxic and have a strong ability to adhere to the urethral mucosa and ascend, it is easy to invade

bladder and kidneys, causing infection. Because the female urethra is close to the anus and the female urethra is much shorter and wider than the male urethra, the urethra of baby girls is often contaminated by feces, making it more susceptible to disease.

(2) Hematogenous infection: Bacteria invade the bloodstream from infection sites in the body (such as tonsillitis, sinusitis, dental caries or skin infection) and reach the kidneys, first causing multiple small abscesses in the renal cortex, and then spreading downward along the renal tubules to the renal papillae, calyces and renal pelvic mucosa. However, inflammation can also start from the papillary collecting ducts with slight damage to the renal papilla (such as crystal damage in the urine) and then spread upward and downward. Blood-borne infection is relatively rare, less than 10%. Hematogenous infection is more common in neonates or hematogenous renal infection in patients with Staphylococcus aureus sepsis.

(3) Lymphatic infection: The lymphatic vessels of the lower abdomen and pelvic organs have many communicating branches with the lymphatic vessels around the kidneys. There are also lymphatic vessels connecting 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.

(4) 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.

The above are the causes of urinary tract infection, mainly some urinary tract infections in the bladder. The common routes of pathogens are mainly some urinary tract infections caused by fungi, bacteria and parasites. You can keep the vulva clean, pay attention to the hygiene of sexual life, avoid changes in DC contactors, and pay attention to a light diet and the intake of some vegetables and fruits.
