[Radiological, biochemical and clinical aspects of uremic osteopathy in patients with long term dialysis].

The clinical, biochemical and radiological signs of uremic osteopathy in 25 patients dialyzed at the dialyzing unit of the Medical Policlinic of the University of Berne are described. Comparison, mainly of radiologic signs, with the published experience of other centers shows a relatively high frequency of nonsymptomatic osteopenia and metastatic and vascular calcifications in our patients, even though their serum calcium and phosphorous concentrations were kept relatively normal. The frequencies of radiologic alterations in other dialyzing units reported in the literature differ widely from one center to another; this may be due to different technology, but even more to varying evaluation of the findings by different radiologists.
