A retrospective analysis of sacral neuromodulation for female overactive bladder and interstitial cystitis/painful blader syndrome / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the effects of sacral neuromodulation (SNM) on female overactive bladder (OAB) and interstitial cystitis/ painful bladder syndrome (IC/PBS).Methods From May 2016 to April 2017,13 patients with OAB or IC/PBS who had been treated with SNM were assessed retrospectively.Among them,6 cases were OAB patients,and 7 cases were IC/PBS patients.The average age was 52.3 (42-67)years old,and the preoperative and postoperative 24 h urine frequency,night urination frequency and average voided volume were compared.Results Totally 13 patients underwent stage Ⅰprocedure.The operation time for stage Ⅰ was 52-125min(average 92 min).After an average follow-up of 3.6 weeks,stage 11 procedures were performed on responders.Four OAB patients accepted stage Ⅱ1 surgery (conversion rate66.7％),and the 24h frequency and night urination frequency reduced from preoperative 22.5 and 5.2 times to postoperative 14.3 and 2.3 times (P ＜ 0.05) respectively,and average voided volume increased from 120.3ml to 166.4ml (P ＜ 0.05).Among 4 patients presenting IC/PBS who had underwent stage Ⅱ surgery (conversion rate57.1％),VAS score and 24 h voiding frequency reduced from 7.3 and 21.6 to 3.8 and 16.8 (P ＜ 0.05),respectively.No adverse event,such as wound infection or electrode translocation was detected during an average follow-up of 8.3 months.Conclusions Stage Ⅰ procedure is crucial for the long term efficacy of SNM.Postsurgical wound management and parameter adjustment are equal essential in order to achieve a maximum benefits.SNM has advantages in minimal invasiveness and less bleeding,which provides a minimal invasive approach for the managemem of OAB and IC/PBS.
