经皮骶神经根电刺激治疗16例顽固性排尿功能障碍

Percutaneous sacral nerve root stimulating on the refractory voiding dysfunction(Report of 16 cases)

目的 :探讨经皮骶神经根电刺激对顽固性排尿功能障碍的治疗作用。方法 :使用美国Medtronic公司经皮骶神经根电刺激器 ,对 16例患者第 3骶神经根行电刺激治疗 ,治疗前后对比分析其主观指标改变及尿动力学变化。结果 :行经皮骶神经根电刺激 1～ 2周后 ,患者排尿次数由 5 2 .8次 / 72h显著减少为 31.3次 / 72h(P <0 .0 5 ) ,膀胱容量由 30 9ml增加为 342ml(P <0 .0 5 ) ,最大尿流率由 12 .4ml/s增加为 14 .1ml/s(P <0 .0 5 ) ,其余主观指标及尿动力学指标变化不显著。结论 :经皮骶神经根电刺激对顽固性排尿功能障碍性疾病有一定疗效 。

Purpose:To evaluate the cure rate of the refractory voiding dysfunction. Methods:16 cases of refractory voiding dysfunction were percutaneous stimulated by the S3 nerve root, and the objective results and the urodynamic parameters were compared before and after the stimulation. Results:After stimulated for 1 to 2 weeks, the times of voiding decreased from 52.8 /72 h to 31.3 /72 h(P< 0.05 ), the capacity of the bladder increased from 309 ml to 342 ml (P< 0.05 ), and the maximum uro flow rate increased from 12.4 ml/s to 14.1 ml/s. Conclusions:Percutaneous sacral nerve root stimulation is useful for the refractory voiding dysfunction, and is referable for the implant sacral nerve root stimulation.
