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.
