What is urinary tract infection? Is there any pathological classification of urinary tract infection?

Urinary tract infection, also known as urinary tract infection (Urinary Tract Infection), is a general term for infections in various parts of the urinary system, such as the kidneys, ureters, bladder and urethra. So how are urinary tract infections classified?

1. Definition of urinary tract infection

Urinary tract infection, also known as urinary tract infection (Urinary Tract Infection), is a general term for infections in various parts of the urinary system, such as the kidneys, ureters, bladder and urethra. Urinary tract infection, also known as urinary infection, is an inflammation caused by bacteria directly invading the urinary tract. The infection can affect the upper and lower urinary tract, and because of the difficulty in localization, it is collectively called urine sensation. Clinically, it is divided into acute and chronic types. The former has an acute onset and typical symptoms that are easy to diagnose, but the symptoms in infancy may be atypical, making diagnosis often difficult. Chronic and recurrent infection can lead to kidney damage.

Classification of urinary tract infections

1. Urinary tract infection can be divided into upper urinary tract infection and lower urinary tract infection according to the site of infection.

2. Based on the relationship between the two infections, it can be divided into isolated or sporadic infection and recurrent infection. Recurrent infection can be further divided into reinfection and bacterial persistence. Reinfection refers to a new infection caused by foreign bacteria invading the urinary system again; bacterial persistence refers to a recurrent infection caused by the same bacteria present in the urinary system (such as urinary stones or prostate disease), also known as recurrence.

3. Since the urinary system and the male reproductive system are anatomically connected pipe systems, it is often difficult to clearly distinguish them clinically when infection occurs. The method of classifying according to the urinary tract status when the infection occurs has greater guiding value for clinical treatment. It can be divided into the following categories: simple urinary tract infection (simple lower urinary tract infection and simple upper urinary tract infection); complicated urinary tract infection (including catheter-related infection, etc.); urosepsis; male reproductive system infection: prostatitis, epididymitis, orchitis, seminal vesiculitis, etc.
