Abstract：Objective: To summarize 14-year experience with sacral neuromodulation (SNM) for lower urinary tract dysfunction at our center.Methods: We retrospectively reviewed the patient database at our center to assess the long-term outcome and incidence of adverse events after sacral neuromodulation implantation for lower urinary tract dysfunction between 2002 and 2016.Results: Between May 2002 and Apr.2016,69 patients were given a preliminary test SNM.In the test phase,the rate of improvement was 100% (7/7) in overactivity bladder,66.7% (6/9) in non-obstructive urinary retention and 50.0% (4/8) in interstitial cystitis.In neurogenic bladder patients,the rate of improvement in dysuria (23.1%,9/39) was significantly lower than in urgency-frequency (54.2%,13/24),urinary incontinence (64.2%,12/19),constipation (63.9%,23/36) and bladder pain (50%,2/4).At last,an implant was performed on 35 (50.7%) patients.The conversion rate from testing phase to implantation phase was 58.3% (14/24) in non-neurogenic bladder patients and 46.7% (21/45) in neurogenic bladder patients.During the follow-up period (35.8±7.7 months),the long-term success rate was 88.6%.Conclusions: SNM is a minimally invasive procedure with a good long-term outcome to treat lower urinary tract dysfunction.
