Urinary Tract Calculi : A population survey in a Dutch community (Hasselt) on the occurence and consequences of "silent stone" disease.

In the Introduction an outline is given of the present study, which had the character of a population survey. It is described that in the literature the incidence of urolithiasis shows great regional variations, probably to some extent being true differences; these differences can also be the consequence of the different parameters used in the studies, like analysis of hospital medical records, studies of a population by means of interviews or postmortem examinations. .
