Abstract: Objective To evaluate sacral nerve stimulation (SNS) in the treatment of spastic pelvic floor syndrome (SPFS).Method In this study,36 patients of spastic pelvic floor syndrome who received SNS treatment from 2011.3 to 2011.12,were reviewed in terms of clinical curative effect,changes of anal pressure and defecography.Result After a course of SNS treatment,patients were followed up for 3 months,12 cases were cured,22 cases improved and 2 cases were ineffective,the total effective rate was 94.4％.The symptoms such as endless defecate feeling,difficulty in defecation,anal pain and anal obstruction feeling improved significantly (P ＜0.01 ).After the therapy,rectal anal reflex( RAR)threshold value volume rose,anal maximum contraction pressure (AMCP),anal rest perssure (ARP) decreased (P ＜ 0.01 ).While the anal longest contraction time (ALCT)and rectal rest pressure (RRP) did not change significantly (P ＞ 0.05 ).After treatment,when patient defecate the anorectal angle (ARA) increases,the puborectal muscle spasm notch (PMSN)attenuates (P ＜ 0.01 ).Conclusions SNS is effective and minimally invasive in treating spastic pelvic floor syndrome.
