Urodynamic parameters as determined by in vivo cystometry. Top table shows mean (SEM) for animals 2, 4, 8, and 12 weeks post-STC. *- Bladder capacity was higher 8 weeks post-STC compared with all other timepoints (P < 0.05). Cystometric parameters at 8 weeks post-STC are further broken down into animals that were imaged via CT, and those that only underwent MRI scanning. Ϯ- Bcap, MV, and Bcom are significantly different between animals with MRI alone (P < 0.05). Bcap- Bladder Capacity, MV- Micturition Volume, RV- Residual Volume, BP- Basal Pressure, TP- Threshold Pressure, MP- Maximal Pressure. Bcom- Bladder Compliance. Lower panels show representative cystometrograms from animals at 8 weeks subjected to MRI alone revealing abnormal readings in the form of non-voiding contractions (arrows)
