We will include randomised controlled trials evaluating suprapubic temperature stimulation for prevention or treatment of POUR, compared with usual care, sham\/no intervention or other non-thermal strategies. Two reviewers will independently screen studies, extract data and assess risk of bias using RoB 2, with arbitration by a third reviewer. Where appropriate, we will pool effects using ORs for dichotomous outcomes and mean differences or standardised mean differences for continuous outcomes, each with 95% CIs.
