Bladder responses to percutaneous electrodes were investigated with stimulation in three male spinal cats. The animals had been spinalized (T1 level lesion) 10 weeks prior to these studies and had been instrumented with chronic bladder had been spinalized (T1 level lesion) 10 weeks prior to these studies and had been instrumented with chronic bladder wall electrodes and suprapubic bladder catheters for filling and pressure recording. percutaneous stimulation in tethered animals was conducted wit hook electrodes inserted with a needle in the abdomen bilaterally adjacent to the bladder trigone. Stimulation was conducted with 40 Hz pulse trains of 10 to 30 mA for three seconds. Stimulation with both percutaneous and chronic electrodes induced high bladder pressures and voiding. In addition, with chronically implanted electrodes, impedance monitoring of bladder volume was found to be an effective recording technique.
在三只雄性脊髓猫中,通过刺激研究了膀胱对经皮电极的反应。这些动物在这些研究前10周已进行脊髓横断(T1水平损伤),并已植入慢性膀胱壁电极和耻骨上膀胱导管用于膀胱充盈和压力记录。在束缚动物中,经皮刺激是通过将钩状电极经针双侧插入膀胱三角区附近的腹部来进行的。刺激采用40Hz的脉冲串,电流为10至30mA,持续三秒。经皮电极和慢性电极刺激均诱发了高膀胱压力和排尿。此外,发现使用慢性植入电极时,膀胱容量的阻抗监测是一种有效的记录技术。
