Medical practice Methods: A questionnaire was distributed to 145 urologists within three training deaneries within England. Results: A response rate of 70% (n = 102) was achieved. The majority of urologists rated their knowledge of acupuncture as low (46%, n = 46) and their general attitude towards acupuncture was neutral (54%, n = 55). The majority of responding urologists (95%) thought that acupuncture may be of value in urological conditions, and acupuncture was suggested to patients by 30 urol- ogists (29%). The urologists most likely to suggest acupuncture to their patients were typically over 40 years of age, more experienced, not in a training post, and since starting their urological career had changed their attitude towards acupuncture. In a multivariate analysis, a change of view regarding the efficacy of acupuncture was found to be the only variable significantly associated with a recommendation of acupuncture to patients. Conclusions: Although overall knowledge about acupuncture was poor, most responding urol- ogists thought acupuncture may be useful for urological conditions. Those who had changed their views were most likely to suggest acupuncture to their patients. Acupuncture for urolog- ical conditions warrants further investigation and, as this study has shown high interest within the urological community large clinical trials involving multicentres may be feasible. © 2010 Elsevier Ltd.
