Urinary tract infection is an infectious disease in which the urinary system is infected with bacteria causing symptoms such as frequent urination, urgency, painful urination, hematuria, pus flowing from the urethra, back pain, fever, etc. It is relatively easy to cure. The common pathogens that cause urinary tract infections are Escherichia coli, Staphylococcus aureus, Streptococcus, Pseudomonas aeruginosa, Clostridium perfringens, Proteus mirabilis, etc. Most lower urinary tract infections are caused by retrograde infection of bacteria from the urethra, while upper urinary tract infections occur after obstruction caused by stones, polyps, etc., or are caused by blood transmission, etc. For lower urinary tract infections, most patients can be cured through urine culture and drug sensitivity tests, and then choose sensitive antibiotics for about 1 week. If the specific infection is caused by urinary tract tuberculosis, anti-tuberculosis treatment is needed, and the treatment period is longer and takes about six months, which is relatively troublesome, and if there is a kidney abscess, surgery is needed if necessary. In summary, for urinary tract infections, most cases are still relatively easy to cure, but if it is a more specific bacterial infection, or if there is a kidney abscess, the treatment will be more troublesome.
