Why is bladder easy to infect?

Bladder inflammation is a common disease of all ages and with the elderly occupying the highest incidence of disease. If left untreated and definitive treatment can cause nephritis, kidney failure.
Bladder inflammation is a very common disease, accounting for more than 50% of urinary tract infections.

Reason

Bladder inflammation in the elderly is most commonly associated with upstream inflammation from the urethra or from bladder stones that cause urine retention or in men due to prostatic disease (benign prostatic hyperplasia, Prostitution by inflammation or cancer) causes difficulty urinating, urinating does not go away, urinary bladder stasis in the bladder. Bladder inflammation may be due to nephritis, or to sepsis (E. coli) or septicemia.

Some older men are meningitis due to urethral obstruction for a variety of reasons (history: urinary retention, urinary retention, gonorrhea due to gonorrhea, Chlamydia ...).

In women, cystitis usually occurs due to urinary tract infections by improper daily hygiene, while urine and anus close together are very susceptible to contamination. In some people due to poor external genital hygiene daily or low pH (less than 5), less active because of weakness, polio, obesity is a good cause for bladder.

In normal people, no urine in the urine. When cystitis is present, it appears that urinary tract infection is present in the urine. Pathogenesis is mainly caused by bacteria, some of which can be caused by fungi, in which the intestinal bacteria occupy the highest rate, E. coli, Proteus, Klebsiella pneumoniae, Enterococcus faecalis. In some cases, staphylococcus aureus, saprophytic staphylococcus, and even staphylococcus aureus may be present. If you encounter these types of bacteria, the treatment is difficult because the resistance to antibiotics is quite strong. The profound cause of cystitis in the elderly is due to the antibody-producing antibodies against the pathogen that gradually declines, so the microorganisms are very susceptible to attack.
