Influence of Morphologic and Urodynamic Factors on Calcium-Containing Stone Formation
Studies on the pathogenesis of urolithiasis have mainly been performed on such aspects as metabolism of calcium1 and other urinary constituents2, 3, and crystallization processes. Although recurrent stone formers are the most appropriate subjects in such studies, stone formation in these patients cannot always be explained by metabolic disorders alone. The stone incidence in the lower calyx of the kidney is significantly higher than in other regions of the kidney4 and stone formation usually recurs on the same side. It is also known that long-term recumbency is one of the causes of stone formation5. Based on these findings, it is speculated that morphologic and urodynamic disorders of the urinary tract may have some bearing on stone formation and passage. In the present study, we examined the relationship between morphologic and urodynamic disorders of the urinary tract and the incidence of stone formation.
