title: [Results of various analysis technics in relation to urinary calculi studies].
abstract: The article describes the results of surveys on renal calculi analysis organised by the Dutch Quality Assessment Foundation (SKZL) over the years 1986-1989. Most of the Dutch laboratories apply wet chemistry, some of them infrared spectroscopy, some polarisation microscopy and one X-ray diffraction analysis. The results of the wet chemistry category are poor, the infrared spectroscopy and the polarisation microscopy group score moderately well while the X-ray diffraction analysis laboratory performs well. On the basis of the results it is suggested to promote the physical chemical methods for renal calculi analysis.
