Before 2009, no controlled trials of percutaneous tibial nerve stimulation (PTNS) for overactive bladder had been reported. However, publication of a randomized unblinded tolterodine-controlled trial of PTNS and the reporting of two blinded placebo-controlled studies now provide level 1b evidence of efficacy. PTNS should, therefore, be considered as a treatment option in this setting.
