Sacral nerve neuromodulation (InterStim). Part III: Case studies

Part III of this sacral nerve neuromodulation (InterStim therapy) series describes two case studies. This article coalesces all the concepts associated with InterStim therapy, including criteria for patient selection, education, surgery, programming, and return visits. The first case study describes a woman with urgency-frequency and urinary incontinence. The second case study discusses a woman with a diagnosis of urinary retention. These case studies provide the reader with successful outcomes with InterStim and its use as a viable treatment option when patients meet the selection criteria.
