Can the PFDI (Pelvic Floor Distress Inventory) or PFIQ (Pelvic Floor Impact Questionnaires) be used to predict outcome in pelvic reconstructive surgery?

To determine a syndrome score threshold on PFDI or PFIQ predictive of a significant improvement in post-operative functional results.A retrospective case review (Canadian Task Force Classification II-2).University and research hospital.Women diagnosed with pelvic organ prolapse and repaired with synthetic vaginal mesh.Quality of life was arbitrarily considered to have improved significantly if the score decreases by more than 50% between pre-operatively and 36 months post-operatively. We investigated the pre-operative cut-off score predictive of no quality of life improvement at M36 from a prospective trial for surgical pelvic organ prolapse treatment.The most accurate pre-operative cut-off score predicting a failure to improve quality of life at 36 months post-operatively was 62/300 (PFDI Score). This cut-off value had a positive predictive value of 83.6% and specificity of 62.1%. No significant threshold was obtained from the PFIQ score.The intensity of symptoms before surgery may interfere as a predictive factor for outcome.
