Urinary tract infections are caused by direct invasion by bacteria (rarely by fungi, protozoa, viruses). Urinary tract infections are divided into upper urinary tract infections and lower urinary tract infections. Upper urinary tract infections refer to pyelonephritis (pyelonephritis is divided into acute pyelonephritis and chronic pyelonephritis), and lower urinary tract infections include urethritis and cystitis. Treatment principles: Treatment of urinary tract infections should first clarify whether the condition is acute or chronic, and also clarify whether it is an upper or lower urinary tract infection, what kind of pathogenic organisms are causing it and how sensitive they are to drugs, how much impact they have on kidney function, whether there is urinary system obstruction and vesicoureteral reflux, and other causative factors. The following principles should be followed in the treatment. (1) Firstly, give sensitive antibiotics according to common pathogenic bacteria. (2) Perform urine culture before treatment, and then adjust the medication according to the drug sensitivity results in a timely manner. (3) Choose antibiotics with high concentration in urine or target organs as much as possible. (4) The course of treatment should be adequate. The use of antibacterial drugs should be continued until 2 weeks after the symptoms disappear and the urine culture turns negative. (5) Avoid misuse of antibiotics, especially avoid nephrotoxic drugs. (6) Predisposing factors must be eliminated at the same time. If there are urinary tract abnormalities or functional abnormalities, they should be corrected or treated accordingly. (7) Strengthen the immune function of the body. (8) Recurrent episodes with the consolidation of Chinese medicine, such as Yinhua urological tablets. The first misconception is the excessive use of antibiotics. When chronic urinary tract infections occur, some patients have symptoms such as frequent urination, urgent urination, and painful urination, so they buy some anti-inflammatory tablets for treatment. However, it is not known that most of these western drugs are antibiotics, which are fast acting but have a lot of toxic side effects and are easy to produce drug resistance when taken for a long time, making future treatment more difficult. The biggest misconception about the treatment of urinary tract infections is that the symptoms are reduced or disappear and then treatment is stopped, but the actual bacteria are not completely eliminated, leading to recurrence of the infection or delayed, and then become chronic. The correct approach is to use sufficient amount of medication for a long time, each time the medication treatment time should not be shorter than two weeks, after the temperature and urine test is normal, and then continue to use the medication for 1 to 2 weeks. Usually, after 1 week and 4 weeks of drug withdrawal, the urine routine or urine culture should be rechecked, and if both results are negative, the infection has been cured. At the same time, we should pay attention to the combination of prevention and treatment, the use of non-toxic side effects of proprietary Chinese medicine such as three gold tablets to treat both the symptoms and the root cause. Myth 3: Condoms can prevent urinary tract infections Many women with untreated urinary tract infections believe that using condoms, female condoms and other tools during sex will prevent further infections. In fact, research data shows that the process of placing or removing contraceptive tools will bring the bacteria in the vagina to the vaginal opening, so the risk of urinary tract infections in women is still relatively high.
