Pudendal nerve stimulation (PNS) inhibited the bladder overactivity caused by 0.25% AA irritation. A: CMG recordings during saline or AA infusion with or without PNS. The PNS duration is indicated by the solid bars under the bladder pressure traces. PNS T was defined as the minimal intensity to induce anal sphincter twitch. T = 0.5 V. Infusion rate = 1 ml/min. B: bladder capacities measured during CMGs under different conditions (n = 12 cats). PNS: 5 Hz, 0.2 ms; T = 0.4–1.4 V. *Significantly different from the AA control before PNS (by one-way ANOVA).
