In women, the urethra is located in the perineum and the urethral opening is located just above the vaginal opening, both within the perineal vestibule. The urethra and vaginal opening are very close to each other, and the female urethra is short and straight, so it is often easy to cause cross-infection. If you don’t pay attention to the hygiene of the perineum and get infected with inflammation of the vagina, it is very easy to lead to urinary tract infections, so you must pay attention to the hygiene of the perineum. During menstruation, you should change sanitary napkins on time, and if vaginal inflammation occurs, it should be treated in time. Normally, you should avoid vaginal secretions contaminating the urethra, and wash the perineum properly with water every day, and it is generally recommended that you wash the urethra first and then the vaginal opening. You should also pay attention to hygiene before and after intercourse.
