Age-Related Characteristics of Linear Dimensions of the Renal Calyces in Mature and Elderly People

In present study we have examined linear dimensions of renal calyx in mature and elderly people and provided their age-dependent characteristics. The material for study included 175 corrosive preparations of pyelocaliceal complexes of kidneys of mature and elderly people. The objective was to study the diversity of morphometric parameters of renal calyces in mature and elderly people. In this study we used the following methods: 1) the production of corrosive preparations of pyelocaliceal complexes; 2) statistical analysis of the obtained data. As a result we found that the diameter of the calyceal fornix varies significantly with age only for the inferior calyx. The width of the cervix of renal calyx was constant across all age groups. Furthermore, it was found that the linear dimensions of renal calyces did not correlate with gender, unlike their quantity which was characterized by a coefficient of quantitative anatomical heterogeneity. Smaller amount of calyces occurs twice as often in men than in women. The results can be used in urological clinic in nephron-urologic surgery (distant shock-wave lithotripsy, percutaneous nephrolitholapaxy, percutaneous puncture etc.). Promising direction is the use of proposed classification of renal morphological and functional calyces for quantitative approach to the diagnosis of norm and pathology of pyelocaliceal complex when using it in ultrasonic, nuclear magnetic resonance diagnostics, computed tomography. ?
