Urinary tract infection is one of the more common infectious diseases in clinical practice, and urinary tract infection is followed by recurrent disease, and urinary infectious diseases have become a major threat to people’s health. The increased incidence in recent years as well as the problem of bacterial drug resistance, the use of new and expensive antibacterial drugs, resulting in increased treatment costs, has caused widespread concern in the medical community and society. In general, urinary tract infections can be cured quickly after reasonable treatment. Due to unreasonable application of antimicrobial drugs, blind medication, destruction of the internal environment, resulting in the rapid development of bacterial resistance; treatment is not standardized, the condition is repeated, resulting in a decline in immunity, making the infection worse or difficult to control, bringing difficulties to treatment. Some patients show recurrent symptoms and repeated positive bacterial cultures, and those who do not recover for a long time can even cause kidney damage. In addition, urinary tract infections often interact with other systemic diseases such as diabetes mellitus and immune deficiency. This has become a serious problem that often plagues patients and can result in poor prognosis if not taken seriously. The anti-infection ward has been engaged in clinical diagnosis and treatment of bacterial infections and basic research on bacterial drug resistance mechanism and bacterial drug resistance monitoring for many years, and has a deep understanding of the characteristics and principles of rational use of antibacterial drugs and the mechanism and development trend of bacterial drug resistance, and has rich experience in the diagnosis and treatment of urinary tract infections. The specialized outpatient clinic for urinary tract infections is now open and is staffed by specialists who are deputy chief physicians or above in the anti-infection department. Through necessary examinations, we can identify susceptible causes and treat them with antibacterial drugs in a reasonable and standardized manner to reduce the possibility of their recurrence.
