The effect of study methodology on reported success rates of the modified Pereyra bladder neck suspension

Abstract

Purpose: We compared surgical results in a cohort of women after modified Pereyra bladder neck suspension using questionnaire based outcomes analysis versus a retrospective chart review.

Materials and methods: Of 151 patients who underwent modified Pereyra bladder neck suspension 102 had complete questionnaire and chart data for review. Mean patient age was 56 years and followup was 25 months.

Results: According to outcomes analysis 48 patients (47.1%) were cured and in 65 (64%) stress urinary incontinence improved compared to 74 (72%) cured and 89 (89%) improved by retrospective review. Of the 102 chart review patients 10 (9%) reported daily pad use compared to 55 of the 102 (53%) in the questionnaire study.

Conclusions: This study controls for patient selection, definition of cure and length of followup, and demonstrates that study methodology profoundly affects reported outcomes for the modified Pereyra bladder neck suspension.
