Table 4 Tukey’s test (or the nonparametric Dunn’s test *) p values for the DTI metrics comparison between each pair of regions: proximal sphincter (PROX) vs. distal sphincter (DIST); proximal sphincter (PROX) vs. membranous urethra (MU); distal sphincter (DIST) vs. membranous urethra (MU). Statistically significant results are highlighted in bold
