Etiology More than 95% of urinary tract infections are caused by a single bacterium.

Among them, 90% of outpatients and about 50% of inpatients, the pathogenic bacteria is Escherichia coli. The serotyping of this bacterium can reach 140 species, causing urinary susceptible Escherichia coli and Escherichia coli isolated from patient stool.The same species of Bacillus is common in asymptomatic bacteriuria or uncomplicated urination; Proteus, Aerobacter, Klebsiella pneumoniae, Pseudomonas aeruginosa, Streptococcus faecalis, etc. are found in reinfection.Urinary tract, urinary tract infection with complications; Candida albicans, new Cryptococcus infections are more common in patients with diabetes and glucocorticoids and immunosuppressive drugs and after kidney transplantation; Staphylococcus aureus is more common in skin wounds and drug usersCaused by bacteremia and sepsis; although viral and mycoplasma infections are rare, there is a gradual trend.
