Posterior Tibial Nerve Stimulation for the Treatment of Detrusor Overactivity in Multiple Sclerosis Patients: A Narrative Review.

Bladder dysfunction, particularly neurogenic detrusor overactivity (DO), poses a substantial challenge in multiple sclerosis (MS) patients, detrimentally impacting their quality of life (QoL). Conventional therapies often fall short, necessitating alternative approaches like posterior tibial nerve stimulation (PTNS) for effective management. This narrative review critically examines the application of PTNS in treating DO among MS patients, aiming to provide a comprehensive synthesis of its efficacy, underlying mechanisms, and clinical outcomes. By evaluating a spectrum of studies, including randomized controlled trials and long-term follow-up research, the review elucidates PTNS's role in enhancing bladder control and ameliorating symptoms of urgency and incontinence, thereby improving patient well-being. Despite its potential, the review acknowledges the limited scope of existing research specific to MS-induced neurogenic DO and calls for further investigation to optimize PTNS protocols and understand its long-term benefits. Highlighting PTNS's minimal invasiveness and favorable safety profile, the review advocates for its consideration as a viable third-line treatment option in MS-related bladder dysfunction management. Through this analysis, the review contributes to the broader narrative of seeking effective, patient-centered therapeutic strategies for MS-related complications, underscoring the importance of personalized care in improving patient outcomes.
