Urinary tract infection is a common and frequent disease in women, often showing symptoms such as frequent, urgent and painful urination. If it is accompanied by fever and significant pain and percussion in the kidney area, it is likely that bacteria have entered the kidney and pyelonephritis has occurred. Some urinary tract infections can be asymptomatic and are often referred to as occult urinary tract infections. Usually, urinary tract infections are caused by bacteria entering the bladder from the urethra. Women are especially susceptible to urinary tract infections because their urethra is shorter and wider, making it easier for bacteria to enter the bladder. After marriage, especially when you are newly married, during sex, if you don’t pay attention to hygiene, you will send bacteria from the urethra and the front part of the urethra into the bladder, and you will be more likely to get a urinary tract infection. About half of the patients with cystitis develop pyelonephritis, which is due to bacteria rising from the bladder into the kidneys. Urinary tract infections rarely occur in young men, and if they do, it is likely that they have bacterial prostatitis. A diagnosis of urinary tract infection can be made if there are very typical symptoms of pyelonephritis, along with a large number of white blood cells on a routine urine test. Otherwise, a clean middle urine bacterial culture count should be done to determine if a urinary tract infection is present when bacteria are clearly present and treated by taking antibacterial medication. Because some patients with non-infectious urinary tract syndrome can also have obvious symptoms such as frequent urination, urgent urination and painful urination, but they are not caused by bacterial infection, and treatment with antibacterial drugs is not only unhelpful but harmful. In addition, urine tests can also rule out sexually transmitted diseases caused by infections such as gonococcus, etiologic, and mycoplasma, because the treatment of STDs and common urinary tract infections is not the same. If urinary tract infections are not treated appropriately and in a timely manner, they may destroy the kidneys, cause uremia and eventually lead to death. Therefore, if you suspect that you have a urinary tract infection, you should go to the hospital as soon as possible for examination, and after a clear diagnosis, take antibacterial drugs for treatment under the guidance of a doctor. At present, the commonly used drugs are ofloxacin, ciprofloxacin and cotrimoxazole, etc. Oxifloxacin and ciprofloxacin are the most commonly used, 200mg twice a day, but pregnant women and adolescents under 18 years old cannot take them. The benefits of cotrimoxazole are reliable efficacy and few side effects, but patients with renal insufficiency need to be used with caution. Patients with cystitis usually only need to take a larger dose of the drug once to cure. Also taking a combination of Chinese and Western medicine is more conducive to the removal of bacteria and shorten the treatment time. For patients who are in poor physical condition and have greater adverse reactions after taking western drugs, a combination of Chinese and Western medicine is the best option. After treatment, patients with urinary tract infections must be followed up and reviewed. Because these diseases are particularly prone to recurrence, and when they recur, they do not necessarily have symptoms, but they hide the risk of damaging the kidneys, the urine bacterial culture count should generally be rechecked once a month for a year. The prevention of urinary tract infection is: 1, try to drink more water, urinate regularly, in order to enter the bladder bacteria flushed out with urine, to reduce the occurrence of disease; 2, women’s vaginal opening, anus, and urethral orifice is very close, if you do not pay attention to the cleanliness of the pubic area, there will be a lot of bacteria around the urethral orifice, easy to cause urinary tract infection, must pay attention to strengthen the cleanliness of the pubic area, the direction of the wipe paper after relieving stool to The direction of wiping paper after relieving stool should be backward, not forward; 3. Do not wash your own underwear and urinary tract infection patients’ underwear together, and do not wear such patients’ underwear. A mother with a urinary tract infection should not put her own underwear and her daughter’s underwear together to avoid infecting her daughter. 4, some women often develop the disease after sexual intercourse, in order to prevent it before it happens, should urinate immediately after sexual intercourse, and take cotrimoxazole 1~2 tablets. Women who already have urinary tract infection had better reduce the number of sexual intercourse, or temporarily stop sexual intercourse to facilitate the treatment of the disease.
