Background and Purpose: This case series focuses on the impact of sacral neuromodulation on quality of life (QOL). InterStim therapy, a form of sacral neuromodulation, has been found to be effective on urinary leakage and frequency, but its effect on QOL has not been determined.
Study Design: This study is a prospective chart review of 3 female patients who underwent implantation of the InterStim device. All patients completed the King's Health Questionnaire on the morning of the procedure and at 3 months postimplantation.
Case Description: Mean age of the 3 subjects was 68 years (range: 63–76 years) and there was variability in patient comorbidities, duration, and range of symptoms. Each patient was evaluated by a family nurse practitioner and was deemed appropriate for implantation after a successful trial period.
Outcomes: Implantation of the InterStim device had a positive impact on QOL for 2 of the patients. The oldest patient, who also had the lowest perceived general health status before implantation and who reported coital incontinence, did not have improvement in QOL.
Discussion: Age, health status before implantation, and coital incontinence seem to have a negative impact on QOL outcomes in patients who undergo InterStim implantation.
