Table 2. Comparative analysis of kidney stone structure types Me–median; MSD – mean stone density; MSL – maximum stone length; HU–Hounsfield Units; [Q1-Q3]–interquartile range; SWs–total number of shock waves required for complete stone fragmentation. *–Kruskal-Wallis test; †–significant difference (p<0.01) compared to type A (post hoc analysis using Mann-Whitney U test); ‡–significant difference (p<0.01) compared to type B (post hoc analysis using Mann-Whitney U test).
