Graphs showing effects of urethane in a cumulative dosing manner (0.01–0.3 g/kg iv) on CMG parameters during single-infusion CMGs (0.04 ml/min; n = 10). PT, pressure threshold for inducing micturition contraction; BCP, bladder compliance; BCD, bladder contraction duration; VV, voided volume; RV, postvoiding residual volume; VE, voiding efficiency. Statistical differences from baseline (BL) are *P < 0.05, **P < 0.01, ***P < 0.001 (by Dunn's multiple comparison test after a Friedman test).
