不同的作者对于泌尿道感染的疗程有不同的意见,由一周至一年以上不等。多数作者认为,短期治疗即可消灭感染,持续治疗可防止再感染的发生。但是否长期治疗较短期治疗确能更有效地防止再感染的发生尚未有定论。作者对45名6月～14岁的泌尿道大肠杆菌感染患儿进行双盲研究,以判定两周和半年疗程对疗效的影响,这些细菌均对磺胺增效合剂敏感。方法是给每个患者使用两周的磺胺增效合剂后。将患者随机分成两组,其中一组继续使用磺胺增效合剂半年(21例),
Different authors have different opinions on the course of urinary tract infections, ranging from one week to more than one year. Most authors believe that short-term treatment can eliminate the infection, continuous treatment can prevent the occurrence of re-infection. However, the long-term treatment of shorter-term treatment is more effective in preventing the occurrence of re-infection has not yet been conclusive. The authors conducted a double-blind study of 45 children with urinary tract E. coli infection from June to 14 years to determine the effect of two weeks and six months of treatment on the efficacy of these compounds, both of which were sensitive to sulfonamide combination therapy. The method is to use each patient after two weeks of sulfonamide combination. The patients were randomly divided into two groups, one group continued to use sulfonamide combination for six months (21 cases)
