水是維持生命不可或缺的元素之一，人體內主要循環是由血液控制，而血液中82%是水，所以也可以說水控制了人體主要循環。此外水質的好壞，常被拿來與尿路結石比例的多寡做呼應，當然尿路結石的成因有許多，包括性別、年齡、遺傳、地區、氣候、季節、飲食、水份攝取、排尿習慣及職業等。許多研究亦指出，國人的生活習慣與尿路結石有顯著之相關性。本研究目的為針對水分攝取品質，來做尿路結石的比例統計，在俗稱好山好水的台灣後山，宜蘭、花蓮、台東，其當地居民腎結石比例是否有較其他縣市為偏低的現象。我們隨機挑選當地200名案例，當中包含自主求診與健檢案例，利用腹部X 光攝影與超音波影像來判讀結石存在與否。結果顯示宜蘭、花蓮、台東對應於其他縣市的尿路結石比例，雖無明顯低下顯示，卻也能再度證實尿路結石比例男大過女的現象，提供統計數據，供各界參考指教。

Water is an indispensable resource to sustain life, and about 82 percent of our blood is water, while the human Systemic circulation supply the blood to all parts of the body, it can be said that water play an important role in maintaining human life. The purpose of this study is to research the influence of water quality in promotion of kidney stone formation. We compared Taipei city, the capital of Taiwan with the three counties of Yilan, Hualien, and Taitung are located in the eastern part of Taiwan, which was developed later than other areas of the island, famous for the best water quality in Taiwan. The study was conducted on a total of 200 local residents from each region (including medical consult patients and health examination volunteer). Abdominal x-rays and sonography may be used to diagnose kidney stones in this study. The results showed that three counties of Yilan, Hualien, and Taitung at eastern part of Taiwan with best water, has no significantly lower portion of local residents who suffer from kidney stone. This research also reconfirms the proportion of men to women in suffering from stones and statistical data provide for public reference.
