Sacral Neuromodulation with the InterStim™ System for Intractable Lower Urinary Tract Dysfunctions (SOUNDS): Results of Clinical Effectiveness, Quality of Life, Patient-Reported Outcomes and Safety in a French Multicenter Observational Study.

Real-world data that support the use of sacral neuromodulation (SNM) for lower urinary tract dysfunctions are of continued interest.

To evaluate the effectiveness, quality of life (QoL), patient-reported outcomes (PROs), and safety of SNM with the InterStim™ system in real life during 1-yr postimplant.

This is a prospective, multicenter, observational study at 25 representative public and private French sites. Eligible patients received SNM therapy for overactive bladder (OAB) and non-obstructive urinary retention based on local standard of care. Overall, 320 patients were enrolled; 247 received permanent implant or replacement; 204 implanted patients completed second follow-up after mean of 10.0±3.8 mo.

Effectiveness outcomes were change in voids, leaks, and catheterizations/day. Other outcomes included validated QoL and disease severity scores as well as PROs and adverse event data. Outcomes at follow-ups were compared with baseline using the Wilcoxon signed-rank test.

Voids in urinary frequency (UF) and leaks/day in urinary urge incontinence (UI) patients were significantly reduced after 10 mo in both de novo (mean baseline voids/day UF de novo: 12.7 vs 8.6 after 10 mo; p<0.001; mean baseline leaks/day UI de novo: 4.3 vs 1.1 after 10 mo; p<0.001) and replacement patients (mean baseline voids/day UF replacement: 11.5 vs 7.9 after 10 mo; p<0.001; mean baseline leaks/day UI replacement: 5.4 vs 1.0 after 10 mo; p<0.001). Disease bother, Urinary Symptom Profile score, and Ditrovie questionnaire score were also significantly improved. Revisions postimplant occurred in 20% of patients including in 9% due to permanent explantation during a mean exposure time of 24.3 mo.

Through a real-life study, SOUNDS (Sacral neuromOdUlation with InterStim™ therapy for intractable lower uriNary tract DySfunctions) confirms the clinical effectiveness, safety, and positive effect of SNM on QoL and PROs for the treatment of OAB patients.

These analyses on French patients who received sacral neuromodulation (SNM) for retention or OAB during a 10-mo period showed that SNM improved OAB symptoms, quality of life, and reduced disease bother. NCT02186041.
