Segmental Acupuncture for Prevention of Recurrent Urinary Tract Infections. A Randomised Clinical Trial.

ABSTRACT

INTRODUCTION AND HYPOTHESIS: Urinary tract infections (UTIs) are a common medical problem and prophylaxis of recurrent UTIs is an ongoing clinical challenge. In the present study we examined whether acupuncture is able to prevent recurrent UTIs in women. METHODS: This multicentre randomised controlled trial, based at a University clinic and private acupuncture clinics, recruited women suffering from recurrent uncomplicated UTIs. Participants were randomised to the acupuncture group or control group. Acupuncture therapy consisted of 12 treatments over a period of 18 weeks, using a set of predefined body and ear acupuncture points. Cranberry products were recommended to all participants as standard of care. RESULTS: A total of 137 women were randomised (68 acupuncture, 69 control group) and occurrence of UTIs at 6 and 12 months could be assessed in 123 and 120 women respectively. Acupuncture combined with cranberry slightly increased the proportion of UTI-free women compared with cranberry alone at 6 months (59% vs 46%, p = 0.2). Between 6 and 12 months the proportion of UTI-free women was significantly higher in the acupuncture group (66 vs 45%, p = 0.03). The number of UTIs decreased from baseline to 12 months in both study groups. The number of UTIs at 12 months was significantly lower in the acupuncture group (median difference 1, p = 0.01). CONCLUSIONS: Segmental acupuncture may be an effective treatment option for women with recurrent UTIs over a longer follow-up period and may limit antibiotics use. Further studies are needed.
