X線廻折法による尿路結石の研究 第III篇:複数尿路結石のX線廻折法による成分比較

Abstract

The following results have been obtained by comp a rative study on multiple urolithiasis on the same patient by X-ray diffraction. 1) In bilateral renal and u r e teral calculi their components were the same or similar to each other side of calculi. 2) All calculi s h owed the same components in multiple renal calculi. 3) No change in component of calculi was found in recurrent calculi developed in a relatively short period. On the other hand, there was change in components of calculi developed in a long period. 4) In the same p atient componts were the same or similar if the time of formation of calculi was the same even if location of calculi was different.
