“…Regarding the technical procedure, several articles were included. In total, 22 studies and 3 abstracts investigated whether technical aspects can predict SNM outcome [10, 13-15, 17, 25, 26, 29, 32-34, 41, 44, 50, 51, 53, 54, 61, 65, 66, 68, 71, 81-83]. Factors that were studied were type of procedure/lead, length of test stimulation, intraoperative testing, and postoperative stimulation parameters.…”

“…None found any correlation between the position (depth, angle, and deflection) and test and long-term success. Loss of efficacy was associated with high stimulation parameters at time of implantation in 1 study [65]. Furthermore, 1 RCT found PNE without fluoroscopy was not inferior to PNE with fluoroscopy [39].…”

Predictive Factors in Sacral Neuromodulation: A Systematic Review

et al. 2021

Introduction: Sacral neuromodulation (SNM) is an effective treatment in patients with overactive bladder syndrome or nonobstructive urinary retention when conservative treatment fails. Several factors that could impact outcome with SNM have been studied. This systematic review investigated these predictive factors and their relevance for clinical practice. Methods: Systematic review according to the PRISMA guidelines was conducted. This review is registered in the PROSPERO register (CRD42015016256). Results: Seventy-eight studies (of which 11 abstracts) were included. Females, younger patients, and a tined lead procedure tend to be predictive in successful SNM outcome. Factors that did not influence SNM outcome were prior back surgery, surgery for stress urinary incontinence, affective symptoms, and duration of complaints. Reduced detrusor contractility is associated with a lower success rate. The level of evidence of most studies (graded according to the Centre for Evidence-Based Medicine) was 3b. Conclusion: Even though this systematic review investigated predictive factors (gender, age, type of procedure, type of lead, and detrusor contractility), no general consensus on predictive factors could be made. Most studies are small, retrospective, and involve a heterogeneous population. Therefore, prospective research in larger specific patient groups remains necessary to find predictors of SNM outcome.

“…In the same program group, alternate stimulation can be performed at one to five different frequency points. 26,27 VFS therapy can break the existing international single CFS treatment paradigm. Meng et al 10 first applied VFS-SNM to a patient with a refractory OAB in 2020 and observed that the patient's OABSS score and QOL score further improved during the VFS phase compared with during the CFS phase.…”

“…Factors related to SNM lead placement have been investigated as a means of optimizing the therapy. The presence of intraoperative motor and sensory responses, 4-6 quantity of responsive electrodes, 7-10 as well as stimulation amplitudes 11-13 have been assessed. This body of work largely suggests successful implantation is driven by achieving intraoperative responses on more electrodes at lower amplitudes.…”

Intraoperative Predictors of Sacral Neuromodulation Implantation and Treatment Response: Results From the ROSETTA Trial

et al. 2023

Purpose: We determined the utility of intraoperative data in predicting sacral neuromodulation outcomes in urgency urinary incontinence. Materials and Methods: Intraoperative details of sacral neuromodulation stage 1 were recorded during the prospective, randomized, multicenter ROSETTA trial, including responsive electrodes, amplitudes, and response strengths (motor and sensory Likert scales). Stage 2 implant was performed for stage 1 success on 3-day diary with 24-month follow-up. An intraoperative amplitude response score for each electrode was calculated ranging from 0 (no response) to 99.5 (maximum response, 0.5 V). Predictors for stage 1 success and improvement at 24 months were identified by stepwise logistic regression confirmed with least absolute shrinkage and selection operator and stepwise linear regression. Results: Intraoperative data from 161 women showed 139 (86%) had stage 1 success, which was not associated with number of electrodes generating an intraoperative motor and/or sensory response, average amplitude at responsive electrodes, or minimum amplitude-producing responses. However, relative to other electrodes, a best amplitude response score for bellows at electrode 3 was associated with stage 1 failure, a lower reduction in daily urgency urinary incontinence episodes during stage 1, and most strongly predicted stage 1 outcome in logistic modeling. At 24 months, those who had electrode 3 intraoperative sensory response had lower mean reduction in daily urgency urinary incontinence episodes than those who had no response. Conclusions: Specific parameters routinely assessed intraoperatively during stage 1 sacral neuromodulation for urgency urinary incontinence show limited utility in predicting both acute and long-term outcomes. However, lead position as it relates to the trajectory of the sacral nerve root appears to be important.
