Causes of urinary tract infections in the elderly

The basic cause of urinary tract infection in the elderly is pathogen infection. The inducing factors include structural urinary tract obstruction, functional urinary tract obstruction, etc.

First, the basic causes

1. Pathogen infection

Escherichia coli, Klebsiella, chlamydia, adenovirus and other pathogens invade the urethra, and local replication causes inflammatory reactions, which can lead to the occurrence of this disease.

Second, the inducing factors

1. Structural urinary tract obstruction

, urinary tract stones, prostatic hyperplasia, urethral tumors and other diseases lead to poor urinary flow, which may increase the risk of urinary tract infection in the elderly.

2. Functional urinary tract obstruction

Bladder-ureteral reflux, neurogenic bladder and other factors lead to functional urinary tract obstruction, which may also increase the incidence of this disease.
