  1. Threshold pressure, pressure at which voiding was initiated; bladder capacity, infusion volume between voids; bladder compliance, bladder capacity divided by the difference between threshold and baseline pressure; *, P < 0.05 versus control; #, P < 0.05 versus AI. None of the parameters were significant between the control and AI-SW groups. Data are presented mean ± SEM. Post-void residual volumes were less than 0.1 ml in all animals.
