title: A simplified sensitive method for the analysis of renal calculi.
abstract: A simple, convenient method for the analysis of renal calculi is presented. The method allows the quantitative estimation of oxalate, urate, calcium, magnesium, xanthine, and phosphate; a qualitative analysis for ammonia, carbonate, and cystine is also done. The estimations can be done with specimens of calculi as small as 1 mg. The results of analyses of some calculi from patients are presented and discussed.
