Urinary tract infection is caused by direct bacterial invasion, which will bring great inconvenience and trouble to patients with urinary tract infection. Zhengzhou andrology experts pointed out that the factors that induce urinary tract infection are mostly external factors. 1, obstruction factor. Such as congenital genitourinary system abnormalities, stones, tumors, strictures, prostatic hyperplasia or neurobladder, which lead to urinary retention and reduce the ability of urethra and reproductive tract epithelium to defend against bacteria. 2. The body's disease resistance is weakened. Such as diabetes, pregnancy, anemia, chronic liver disease, chronic kidney disease, malnutrition, tumor and congenital immunodeficiency or long-term treatment with immunosuppressants. 3. Iatrogenic factors. Such as indwelling catheter, repeated catheterization, urethral dilatation, prostate biopsy, cystoscopy and other operations, due to mucosal abrasion or neglect of aseptic concept, it is easy to attract pathogenic bacteria, induce or spread infection. These are the factors that induce urinary tract infection. If you are a patient with urinary tract infection, while choosing a professional hospital to treat urinary tract infection, make clear the cause to avoid misdiagnosis.
