Knowledge of the composition of human urinary calculi within a geographical area can lead to an understanding of the epidemiology of renal stone disease. Studies in the Durban area, with its high incidence of kidney and bladder stones, indicate that calcium oxalate is the overwhelmingly dominant (circa 80%) component, followed by uric acid. An important feature is the low occurrence of phosphate stones, especially those containing struvite.
了解特定地理区域内的尿路结石成分有助于了解肾结石病的流行病学。在德班地区（肾结石和膀胱结石发病率较高）进行的研究表明，草酸钙是绝对主要的成分（约占 80%），其次是尿酸。一个重要特征是磷酸盐结石的发生率较低，特别是那些含鸟粪石的结石。
