title: [Evaluation of 7 methods of analysis of urinary calculi].
abstract: We assess seven methods of analysing urinary stones which we have used to study a total of 893 cases of lithiasis. For the purpose of a routine identification of the components, we consider the Immersion Method to be the best technique, followed by X-Ray Diffraction or Infrared Spectroscopy. We reject Scanning, qualitative, chemical analysis and quantitative, chemical analysis because of their drawbacks. For research purposes, we favour the "fine plate" supported by X-Ray Diffraction and Infrared Spectroscopy.
