The most common cause of urethral pain in women after urination is urinary tract infection. Because women’s physiology is more prone to urinary tract infections than men’s, because women’s urethra is relatively short and straight, and the opening of the urethra is close to the perineum, it is easy for bacteria to attack the urethral opening and infect the urinary tract through the urethral opening, which can lead to urinary tract infections. If the above symptoms occur, it is recommended to go to the hospital to check the urine routine, if there are elevated white blood cells in the urine, you can be sure that there is a urinary tract infection. The majority of bacteria that cause urinary tract infections are gram-negative, so in the choice of antibacterial drugs, you need to choose antibiotics whose antibacterial spectrum covers gram-negative bacteria. The more commonly used ones are quinolones, and levofloxacin or fosfomycin are usually chosen as the first choice of medication for treating urinary tract infections, with a dosing cycle of 3-7 days.
