The primary outcome will be the variation of urinary urgency and incontinence. It will be evaluated by self-reported measuring scales, such as the Overactive Bladder Questionnaire (OAB-q) and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) in their Italian forms.
The expected outcome is that the treatment of posterior tibial nerve stimulation will reduce the frequency and the urgency of urination, and urinary incontinence. Moreover, results from the follow-up will allow estimating the duration of the expected outcome.
