Retrospective regression analysis of animals subjected to STC reveals a predictive value for CT Scanning. This graph represents 2 week CT and 8 week cystometric data from 4 animals in this study, along with 3 animals from a previous study (Burmeister et al., 2010). a X-axis represents bladder volume 2 weeks post-STC as determined by CT Scanning, and Y-axis represents maximum pressure (MP) generated by bladders 8 weeks post-STC as determined by in vivo urodynamic studies in the SAME ANIMAL. b Representative cystometrograms at 8 weeks and (c) CT scans at 2 weeks of 3 individual animals. This analysis displays that animals with minimal bladder growth seen upon CT scanning 2 weeks post-STC (left of the dashed lines) display bladder overactivity (arrows show non-voiding contractions), while the animal with a large bladder volume 2 weeks post-STC (right of the dashed lines) generates low maximum pressures (i.e. ~13 cmH2O). Normal bladder function was seen in animals with intermediate bladder volumes determined by CT 2 weeks post-STC. y = −46.65x + 52.12, r = 0.82, P = 0.02
