The hypothesis for this study is that bilateral sacral neuromodulation will improve symptoms of interstitial cystitis by at least 25% when compared to unilateral sacral neuromodulation as reported by patient's responses to the Interstitial Cystitis Symptom and Problem Indices.

This study will be a prospective randomized study comparing bilateral to unilateral sacral neuromodulation. The study population will include all patients diagnosed with interstitial cystitis, using the NIDDK criteria, having staged sacral neuromodulator stimulators placed at Hahnemann University Hospital.

Further study details as provided by Drexel University:

Primary Outcome Measures:
  • To determine if bilateral sacral neuromodulation will reduce the patient's score on the Interstitial Cystitis Symptom and Problem Questionnaire by at least 25% when compared to unilateral sacral neuromodulation in patients with interstitial cystitis. [ Time Frame: Post-op, at 6 weeks and at 3 months post-surgery ]

Secondary Outcome Measures:
  • To determine if bilateral sacral neuromodulation will improve the patient's voiding diary defined as reduction in urinary frequency by 25% from baseline when compared to unilateral sacral neuromodulation in patients with interstitial cystitis [ Time Frame: Post-op, at 6 weeks and 3 months post-surgery ]

Estimated Enrollment: 50
