title: [Grouping of urinary stones and exactness of analyses (author's transl)].
abstract: The composition of 1,327 urinary stones by X-ray diffraction is statistically analyzed, and the exact analyses are discussed. The representative test portion of the urinary stone is important to the result. A comparison of different results of urinary stones with that of other authors is only possible when we know the exactness of the method.
