Urinary tract infection is a common and frequent clinical disease, mainly seen in women. In clinical practice, there are some people who have recurrent urinary tract infections, and there are often certain reasons why they should go to the urology department of a regular hospital for further consultation and treatment. The reasons for this may include: i. Urological tuberculosis, which is often treated with the application of common antibiotics and cannot be completely cured. Second, there may be urological malformations, such as horseshoe kidney, duplicate kidney, duplicate ureter, etc. Third, stones in the urinary system. Stones can cause obstruction, can cause hydronephrosis, and can easily cause secondary urinary tract infection. Fourth, for men, prostatic hyperplasia and prostatitis should be excluded. Patients often have difficulty urinating, do not urinate cleanly, and are prone to urinary tract infections. Fifth, elderly people who are in poorer health, have low immunity, diabetes, and are bedridden for a long time are prone to recurrent urinary tract infections.
