Sacral Nerve Stimulator Revision Due to Somatic Growth

Purpose: Sacral nerve modulation is a Food and Drug Administration approved treatment for refractory urgency, frequency, urge incontinence and nonobstructive urinary retention in adults. The sparse literature on sacral nerve modulation in children focuses on its initial efficacy in patients with neurogenic bladder and dysfunctional elimination. We describe our initial experience with sacral nerve modulation and the phenomenon of growth spurts associated with lead malfunction that necessitates revision.Materials and Methods: After receiving institutional review board approval we retrospectively reviewed the charts of pediatric patients who underwent sacral nerve modulation surgery at our institution. Charts were examined for patient demographics, subjective success, the need for further surgery and success after revision.Results: Four patients underwent sacral nerve modulation at an average age of 12.1 years. All patients reported initial success, defined as greater than 50% symptom improvement. Subsequent...
