A) Representative images of void spot assay (VSA) sheets under ultra violet illumination. B) The number of voiding events with greater than 0.5 μL calculated volume, C) mean voiding volume, and D) total volume of urination in a 4 hr. period was determined by analyzing the images. *, †, and ‡ indicate a statistical difference with a p value of less than 0.05 to the saline control group, intact mice, and the polymer without SAGE, respectively. Samples were statistically analyzed via a 1-way ANOVA with Bonferroni Post-Test. Each experimental group contained 6 animals.
