小引人体结石中的胆结石和尿路结石,为结石病中的常见病和多发病。而尿路结石似乎又有地区性的特点,以四川而论,川南多见,川北少见。上述两种结石病的病因和发病学,国内外虽然研究了数百年,但至今尚未查明,因而治疗也就存在问题。我们从医学地质学的观点,研究了这些结石的物质成分及其结构构造特点也许有助于这个问题的解决。 Small lead body stones in the gallstones and urinary tract stones, stone disease in the common and frequently-occurring disease. The urinary tract stones seem to have regional characteristics, in terms of Sichuan, Sichuan more common, rare in northern Sichuan. The two causes and pathogenesis of stone disease, although the study at home and abroad for hundreds of years, but so far not yet identified, so the treatment there are problems. From the medical geology point of view, we have studied the physical composition of these stones and their structural features may help solve this problem.
