Mild urinary tract infections can have a chance to heal on their own. Urinary tract infection is an infectious disease caused by bacterial infection of the urinary system, resulting in frequent urination, urgent urination, painful urination, hematuria, back pain, fever and other symptoms, which is relatively easy to cure. The common pathogens that cause urinary tract infections are Escherichia coli, Staphylococcus aureus, Streptococcus, Pseudomonas aeruginosa, Clostridium perfringens, and Proteus mirabilis, etc. Most lower urinary tract infections are caused by retrograde infection of bacteria from the urethra, while upper urinary tract infections are most often seen after obstruction or bacterial infection caused by stones or due to blood transmission. For lower urinary tract infections, most patients can be cured through urine culture and drug sensitivity tests, and then select sensitive antibiotics for about 1-2 weeks. 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. To sum up, for urinary tract infections, most cases are still relatively easy to cure, and some patients can achieve self-healing by drinking a lot of water and eating a light diet. In the case of more specific bacterial infections, or in the case of perinephric abscesses, the treatment can be more troublesome.
