DIETARY_SUPPLEMENTD-mannose

Give patients D-mannose, twice a day, one tablet each time, for one year; the research area is divided into two groups, The first group took D-mannose for one year. After the one-year period expired, the use of D-mannose was suspended, and the original standard treatment was resumed treatment, and continued follow-up in the outpatient clinic for one year; the second group maintained the standard treatment for one year, and began to take it after the one-year period expired. Use D-mannose for one year; the grouping method is based on the order of admission of patients in each hospital, with odd-numbered cases in the first group and even-numbered cases in the first group and Second groups. Such patients are fixed in the outpatient clinic to change the urinary catheter every month, so the follow-up time is also arranged during the return visit.
