了解泌尿系结石患者对饮食营养与结石病关系的掌握情况。

选取2014年5月到2015年1月间就诊于中山大学附属第三医院泌尿外科的60例泌尿系结石患者，对其进行饮食习惯及营养知识的问卷调查并进行相关分析。

收回有效问卷60份。结果显示93.3%的患者缺乏营养知识；患者的饮食结构中存在尿石症形成的高发风险，其中93.3%的患者日饮水量少于2 000 ml，61.7%的患者每日摄入过量的动物性蛋白，70%的患者每日摄入钙不足。

大部分泌尿系结石患者对饮食营养与疾病认知不足。因此，加强营养知识教育，了解疾病与营养的关系，建立健康的营养膳食结构有利于泌尿系结石的防治。

To evaluate the relationship between dietary nutrition and stone disease in patients with urolithiasis.

Sixty urolithiasis patients were admitted to the Urology Department of the Third Affiliated Hospital of Sun Yat-Sen University from May 2014 to January 2015. A questionnaire survey was conducted on the dietary habits and nutritional knowledge of these patients. The relevant analysis was conducted by adopting qualitative and quantitative descriptive research method.

Sixty valid questionnaires were received. The results showed that 93.3% of the patients lacked nutrition knowledge. There was a high risk of urinary calculus formation in the patient's diet structure. Among them, 93.3% of the patients drank less than 2 000 ml water per day, 61.7% of the patients consumed excessive animal protein per day, and 70% of the patients consumed insufficient calcium per day.

Most patients with urolithiasis have insufficient knowledge of the relationship between diet nutrition and disease. Therefore, strengthening nutritional knowledge education, understanding the relationship between disease and nutrition, and establishing a healthy nutritional diet structure are conducive to the prevention and treatment of urinary stones.
