Recurrent urinary tract infections are more common in women of all ages because the urethra is shorter and wider in women, and because vulvar and vaginal infections also tend to cause urinary tract infections. In some women, the urethral opening is close to the vaginal opening, so it is easy to be traumatized during sexual intercourse and cause inflammation, especially when sexual intercourse is too frequent; some women do not pay attention to hygiene during menstruation and cause urinary tract infections; some women have an upturned hymen covering the lower part of the urethral opening, forming the “urethral obstruction syndrome”, where a drop of urine is always left after urination. There, bacteria can easily breed and multiply here causing inflammation. Some women have developed the bad habit of “holding urine”, and some are even reluctant to drink water in order to reduce the trouble of going to the toilet, which increases the chances of recurrent urinary tract infections. Usually, at the onset of acute urethral cystitis, patients have the feeling of frequent urination, urgent urination, painful urination and painful abdominal drop, and in severe cases, even bloody urine is visible to the naked eye. Other patients have some atypical symptoms such as back pain, weakness and leg weakness. After the occurrence of urinary tract infection, the treatment is not complete, the bacteria are not completely killed and then stopped, the residual germs are still lurking there, once encountered with fatigue or lower body resistance, the residual latent bacteria again breed and multiply, which is a cause of recurrent urinary tract infections. The fact that people with urinary tract infections also suffer from congenital malformations, obstructions and stones is also an important trigger for recurrent urinary tract infections. In addition if the patient also has a combination of diabetes, neoplastic diseases, after radiotherapy, etc. is also a cause of recurrent disease. Therefore, patients should pay special attention to the following matters: (1) When consulting about the disease, be sure to tell the doctor about the above-mentioned medical history, as well as your previous medication history and efficacy, so that we can develop a more suitable antibacterial treatment plan for you. (2) Treatment must be thorough and should not be discontinued until the symptoms improve slightly, but only after the routine urine examination is normal and the urine culture is negative. (3) To develop the habit of drinking more water, urinary distension must go to the toilet to urinate, drink more water and urinate more, and constantly flush the bladder and urethra is a good way to urinary tract health. (4) Pay attention to menstrual hygiene, those patients whose onset is closely related to sexual intercourse, urinate immediately after sexual intercourse, and take anti-inflammatory drugs to prevent urinary tract infections. (5) For older women with urinary tract infections, in addition to antibacterial drugs, physicians will add estrogen therapy as appropriate to the patient’s condition. (6) Patients with urinary tract obstruction, congenital malformations or urinary tract stones are treated by urologists on a case-by-case basis. Constant renewal of urine in the bladder and frequent urination and flushing of the urethra are important factors in preventing and reducing urinary tract infections.
