The prevention of urethritis should pay attention to the following two problems: the first is the problem of personal hygiene. Pay attention to the washing and cleaning of the vulva especially for women, because women’s urethra is relatively short, more likely to cause urethral infection, so more attention should be paid to, if the symptoms of urethritis, you need to go to the hospital in time. The second is the need for cleanliness. Because most UTIs are associated with infections caused by sexual contact, so sexual contact should pay attention to strengthen this aspect of the protection.
