Urinary tract infection is a common infectious disease of the urinary system, which can develop in both men and women. The main symptoms are frequent urination, urgent urination, painful urination, pus flowing from the urethra, fever, chills, and back pain, etc. The main reason for its appearance is retrograde bacterial infection. Due to the female physiological anatomy, women are more prone to morbidity, especially lower urinary tract infections, such as urethritis and cystitis. The urethra of women is short, wide and straight, so it is easier for bacteria to enter the urethra retrogradely from the urethra and cause urethritis and cystitis, especially in women with vaginitis and women who have unclean sex. The actual UTIs are usually a lot more than just a few of the most popular ones. The main symptoms are frequent urination, urgent urination, painful urination, serious hematuria, abdominal pain, fever and other symptoms.
