This study aims to review the use of sacral neuromodulation in the patient population with painful bladder syndrome/interstitial cystitis (PBS/IC), chronic pelvic pain (CPP), and sexual dysfunction. A literature review of the current research was carried out. This article highlights the current research findings and uses of sacral neuromodulation in patients with PBS/IC, CPP, vulvar vestibulitis, and erectile dysfunction. Current research on sacral neuromodulation on the abovementioned patient population has shown potential efficacy in pilot studies, though larger, multi-centered trials with long-term follow-up are needed.
