Distribution of different stone types across age groups and stone locations. (A) The distribution of different stone types across age groups. Kruskal–Wallis tests (H = 78.388, p < 0.001) revealed significant differences between different age groups and stone types. (B) Significant differences in the distribution of different stone types among different anatomical sites (Fisher's exact test, p < 0.001; Cramer's V = 0.108, p < 0.001). (C) The normalized Adj.R values were represented on a heat map, where a higher convergence to red indicates a stronger association. The red color indicates that ST is more likely to be found in the kidney, CaOx in the ureter, UA in the bladder, and rare stones in the urethra, relative to other stone types.
