title: [Experiences with instrumental methods for urinary calculi analysis].
abstract: To reduce the urinary calculi incidence by calculi formers, it is important to know the composition of these stones. Unfortunately the chemical analysis does not give very reliable results. Looking for a better method to analyse urinary calculi, three instrumental methods were tested: infared spectroscopy, thermal analysis and X-ray diffraction. The experimental results and economical considerations show that the X-ray diffraction analysis of urinary calculi would meet the goal of improved care of patients with stones.
