Abstract
Introduction: Implantable tibial neuromodulation (iTNM) systems have recently become commercially available in the US, and offer a new method of neurostimulation for the treatment of overactive bladder (OAB). In the absence of head-to-head studies, the aim of this meta-analysis was to indirectly compare the efficacy and safety of sacral neuromodulation (SNM) and implantable tibial neuromodulation (iTNM) for the treatment of OAB.
Methods: A comprehensive search was performed using terms for OAB and neuromodulation. Primary efficacy measures included a ≥ 50% reduction in urgency urinary incontinence (UUI) episodes, urinary frequency, and/or OAB symptoms. Primary safety measures included the rate of device-related adverse events (AEs).
Results: A total of 20 studies met selection criteria, encompassing 1416 patients treated with SNM and 350 patients treated with iTNM. No comparative or placebo-controlled studies for SNM and iTNM were identified, and therefore the analysis was completed using single-arm results. Weighted averages showed that the UUI responder rate was similar for both SNM and iTNM (71.8% and 71.3%, respectively). Similarly, weighted averages of OAB responder rates were 73.9% for SNM and 79.4% for iTNM. Similar rates of device-related AEs were also observed.
Conclusions: This meta-analysis found similar efficacy and safety of SNM and iTNM for the treatment of OAB and UUI, including UUI and OAB symptom response rates, reduction in UUI episodes, significant improvements in quality-of-life (QoL), and low rates of procedure and device-related adverse events. Notably, this comparable efficacy was seen without the use of a trial phase of neuromodulation in the iTNM studies versus SNM studies.
期刊介绍：
Advances in Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all therapeutic areas. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Advances in Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
