METHODS The incidences of nephrolithiasis in 12 regions of Japan were calculated on the basis of patient data, obtained in 2005, from 430 hospitals (n = 92,797). Nutrition intake data were extracted from the National Health and Nutrition Survey, conducted in each region by the Japanese Ministry of Health, Labour and Welfare. The association between the incidence of nephrolithiasis and the average intake of various types of food (cereals, potatoes, sugars, legumes, vegetables, fruits, seafood, meat, egg, etc.) or nutrients (proteins, lipids, carbohydrates, salt, potassium, calcium, vitamins, etc.) was examined according to the region; the association between stone composition and nutritional data was also examined. The association between the incidence rate of nephrolithiasis in each region were also analyzed relative to the nutritional intake. RESULTS Continuing surveys in Japan show fixed variations in the incidence of nephrolithiasis among geographic regions. The national average number of patients with nephrolithiasis was estimated to be 203.1 per 100,000 citizens. The intake of fruit was negatively correlated with the incidence of nephrolithiasis (r = -0.721, p = 0.008), whereas the intake of eggs (r = 0.537, p = 0.072) and sugar (r = 0.475, p = 0.119) tended to positively correlate with the incidence (Figure). The intake of potassium (r = -0.500, p = 0.098), vitamin K (r = -0.562, p = 0.057), and pantothenic acid (r = -0.560, p = 0.058) tended to negatively correlate with incidence. The proportion of uric acid stone patients, based on an infrared analysis of 8,877 upper urinary tract stones, was 4.5% for Japan. The intake of potatoes, vegetables, and confectionery was positively correlated with the content of calcium in stones (r = 0.676, p = 0.016; r = 0.614, p = 0.034; and r = 0.692, p = 0.013, respectively). CONCLUSIONS The incidence of nephrolithiasis is higher in geographic areas where the populations have low fruit and high sugar intake. These data are useful as a basis for investigating risk and nutritional factors associated with nephrolithiasis. © 2013 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 189Issue 4SApril 2013Page: e861 Advertisement Copyright & Permissions© 2013 by American Urological Association Education and Research, Inc.MetricsAuthor Information Takahiro Yasui Nagoya, Japan More articles by this author Atsushi Okada Nagoya, Japan More articles by this author Li Zuo Nagoya, Japan More articles by this author Yasuhiko Hirose Nagoya, Japan More articles by this author Kazumi Taguchi Nagoya, Japan More articles by this author Takahiro Kobayashi Nagoya, Japan More articles by this author Masahito Hirose Nagoya, Japan More articles by this author Ryosuke Ando Nagoya, Japan More articles by this author Shoichi Sasaki Nagoya, Japan More articles by this author Kenjiro Kohri Nagoya, Japan More articles by this author Expand All Advertisement Advertisement PDF DownloadLoading ...
