OBJECTIVE: To determine a syndrome score threshold on PFDI or PFIQ predictive of a significant improvement in post-operative functional results.

DESIGN: A retrospective case review (Canadian Task Force Classification II-2).

SETTING: University and research hospital.

POPULATION: Women diagnosed with pelvic organ prolapse and repaired with synthetic vaginal mesh.

METHODS: 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.

RESULTS: 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.

CONCLUSION: The intensity of symptoms before surgery may interfere as a predictive factor for outcome.
