The Effect of Sacral Neuromodulation in Ambulatory Spina Bifida Patients with Neurogenic Bladder and Bowel Dysfunction

Abstract OBJECTIVES To assess the effect of sacral neuromodulation (SNM) in ambulatory spina bifida patients with neurogenic bladder and bowel dysfunction. MATERIALS AND METHODS We retrospectively reviewed the records of 29 ambulatory spina bifida patients with neurogenic bladder and bowel dysfunction who underwent SNM testing from July 2012 to January 2020. Clinical data and video-urodynamic parameters were collected and compared using the t-test and the chi-square test. The potential risk factors were considered by logistic regression analysis. P RESULTS In the test phase, twenty-one patients (72.4%) achieved successful improvement of at least one symptom. The success rate for chronic urinary retention (26.09%) was significantly lower (p CONCLUSIONS SNM is effective for neurogenic bladder and bowel dysfunction in patients with ambulatory spina bifida, especially in those without chronic urinary retention. And SNM can also significantly improve the urodynamic parameters of these patients during the storage period.
