Primary Outcome Measures:
  • FI - number of FI episodes per week and/or number of days with FI per week. Constipation - number of bowel movements per week; &/or decrease defecations requiring straining; &/or decrease defecations where there was incomplete emptying [ Time Frame: Annually ]

Secondary Outcome Measures:
  • FI-number of days with staining/week;urgency with continent bowel movements; Improvement in QOL;* Improvement in anal canal pressure. Constipation - Improvement in Wexner constipation score; QOL. [ Time Frame: Annually ]

Estimated Enrollment: 140
Study Start Date: November 1998
Study Completion Date: September 2012
Primary Completion Date: December 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: InterStim therapy
Patients being treated with sacral neuromodulation with InterStim therapy.
Device: Type: Implantable neurostimulator; InterStim
