- Abstract
Objective: The understanding of the utility of sacral neuromodulation (SNM) for neurogenic lower urinary tract dysfunction (NLUTD) is limited, with only small series in the literature and to our knowledge, no published Australian data. The aim of this study was to evaluate the clinical outcomes of SNM for treatment of NLUTD in Australian patients. Materials & methods: A retrospective analysis of patients who received a permanent SNM implant between December 2014 and March 2021 was conducted. Patients completed a urodynamic test pre-operatively. They completed a 3-day bladder diary, uroflowmetry and post-void residual (PVR) measurement pre-operatively and at 6-monthly intervals post-operatively following SNM insertion. Urinary function, patient reported outcome measures and adverse events were assessed. This study was approved by the local human research ethics committee. Results: A total of 36 patients received a permanent SNM implant. The mean follow-up duration was 25±20 months, with the majority (89%, n=32) of patients reporting a >50% improvement on bladder diary evaluation. There was a significant increase in void volume (p<0.001), decrease in PVR (p<0.001), decrease in voiding frequency (p<0.001), decrease in incontinence episodes (p=0.002) and decrease in pad number (p<0.001). There was no significant difference in peak flow (p=0.21). There was no significant difference in SNM efficacy between patients with progressive or non-progressive neurological conditions. Conclusion: SNM is a safe and effective therapy for NLUTD in the context of both progressive and non-progressive neurological conditions. It should be offered more readily to patients with NLUTD given it is a minimally invasive treatment option with potential to make clinically meaningful improvement to quality of life.
