电刺激盆底肌对膀胱功能影响的实验研究

Effect of pelvic floor stimulation on the bladder function in goats

目的 探讨电刺激对膀胱功能的影响。 方法 将 18只羊随机分为刺激和对照两组 ,刺激组以电流刺激盆底肌 ,对照组只放置电极而不予通电 ,其余条件相同。观察尿动力学等指标变化。 结果 刺激组膀胱容量明显增高 (2 4% ) ,逼尿肌压显著降低 (2 4% ) ,逼尿肌细胞代谢水平下降 ,收缩受到抑制。 结论 电刺激可抑制膀胱收缩 。

Objective To study the effect of pelvic floor electric stimulation on bladder function in goats. Methods 18 goats were randomized into the stimulating and the control group. Results In the stimulating group,the bladder capacity significantly increased by 24%,the voiding pressure significantly declined by 24% and the metabolic level of the detrusor cells is significantly lower. Conclusions Electric stimulation of the pelvic floor would inhibit bladder contraction and may be helpful in the management of instable bladder and stress incontinence.
