Abstract
OBJECTIVES: The purpose of this meta-analysis was to evaluate the efficacy and safety of tibial nerve stimulation (TNS) versus antimuscarinic agents in the management of overactive bladder (OAB) syndrome. METHODS: The databases MEDLINE, EMBASE, the Cochrane Controlled Trial Register of Controlled Trials from 2000 to May 2021 were searched to identify randomized controlled trials that referred to the use of TNS and antimuscarinic agents for the treatment of OAB syndrome. A systematic review and meta-analysis was conducted. RESULTS: Eight publications involving 420 patients were included in the meta-analysis. In the analysis, we found TNS had a comparable effect with antimuscarinic agents on micturition per day, nocturia, urge incontinence, and voided volume (P = .9; .4; .78; .44, respectively). Scores measured by questionnaires Overactive Bladder Symptom Score and Overactive Bladder questionnaire Short Form items also indicated no statistical difference between 2 groups. TNS group had a significantly less discontinuation rate and adverse events (P = .003; .0001). CONCLUSIONS: TNS is as effective as antimuscarinic agents for the treatment of OAB. Moreover, TNS appears to be more tolerable and safer than antimuscarinic agents.
