Patients with recurrent urinary tract infection were allocated at random to two weeks' or six weeks' treatment with an appropriate antibacterial drug. There was no difference in the results achieved by the two different periods of treatment as judged by the presence of infection in the urine one week and six weeks after treatment was stopped.The urine was clear of infection in a higher percentage of patients following a course of nitrofurantoin than following a course of ampicillin, but the difference was not significant.
复发性尿路感染患者被随机分配接受为期两周或六周的适当抗菌药物治疗。根据治疗停止后一周和六周时尿液中是否存在感染来判断，两种不同疗程的治疗效果并无差异。服用呋喃妥因疗程后的患者尿液清除感染的比例高于服用氨苄西林疗程后的患者，但差异不显著。
