Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.		Post-op, at 6 weeks and at 3 months post-surgery
Secondary	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		Post-op, at 6 weeks and 3 months post-surgery
