1. Urinary tract infection

Urinary tract infection refers to inflammation of the urinary tract caused by the proliferation of a large number of microorganisms in the urinary tract, which may or may not have clinical symptoms. Depending on the different microorganisms, it can be divided into bacterial infection and fungal infection. Bacterial urinary tract infection is the most common clinical condition. Depending on the cause, pathophysiology and treatment methods, urinary tract infection can be divided into uncomplicated urinary tract infection and complicated urinary tract infection.

Patients with uncomplicated urinary tract infection often have no physiological or anatomical abnormalities of the urinary tract, nor a recent history of urinary system surgery or interventional treatment. Their typical clinical manifestations are bacteriuria or pyuria, and some patients have hematuria. According to the site of infection and clinical severity, it can be divided into acute cystitis (lower urinary tract infection) and acute pyelonephritis (upper urinary tract infection).

Complicated UTIs often occur in patients with urinary tract obstruction, anatomical or functional abnormalities, or in patients who have recently undergone urinary tract surgery or catheter intervention.
