Abstract
AIMS: We desire to evaluate whether utilization of ≤3 V (new experimental approach) vs the traditional four or more volts for lead motor response during stage 1 sacral neuromodulation may impart an improvement in voiding and pain parameters. METHODS: An observational, retrospective, double cohort review was conducted of 179 female patients who experienced medically recalcitrant interstitial cystitis (IC) or bladder pain syndrome (BPS) between January 2002 and January 2013. Group A included 105 women with a motor response of ≤3 V; group B was comprised of 65 women with a motor response at ≥4 V for medically recalcitrant IC or BPS. Patients completed a 3-day pre- and postoperative voiding diary, visual analog pain (VAP) scale, pain urgency frequency (PUF), and Patient Global Impression of Improvement (PGI-I) questionnaire. RESULTS: The mean (standard deviation) follow-up in months was 120.1 ± 33.3 in group A and 116.3 ± 29.2 in group B (P < .45). A successful conversion from stage 1 to stage 2 showed statistically significant improvement for group A compared with group B (95.4% vs 73.8% conversion rate; P < .001). The success rate also favored group A, with 87.6% success compared with 66.2% for group B (P < .002). Group A mean postoperative VAP scores improved over group B with 3.3 ± 1.2 compared with 5.0 ± 0.8 (P < .001). Group A mean postoperative PUF scores were 10.2 ± 2.7 and group B 14.7 ± 3.5, (P < .001). CONCLUSIONS: In the ≤3 V patient cohort, a compelling, significant statistical improvement was noted in most clinical voiding parameters, including the VAP, PGI-I, and performance questionnaires.
