Causes of urinary tract infection after indwelling catheter

The causes of urinary tract infection after indwelling catheter usually include poor nursing, mucosal damage, poor tightness of urine drainage system, etc. The specific analysis is as follows:

1. Poor nursing

After indwelling catheter, the family members do not pay attention to the nursing of urethral parts, and do not regularly clean and disinfect, resulting in bacterial breeding and entering the urinary catheter through the urethral orifice, resulting in infection.

2. Mucosal damage

If urethral mucosa is damaged during indwelling catheter, the damaged part is easy to be invaded by bacteria, resulting in urinary tract infection.

3.

Poor tightness of urine drainage system easily leads to backflow of contaminated urine into bladder, resulting in urinary tract infection.
