Primary surgical repair of anterior vaginal prolapse: a randomised trial comparing anatomical and functional outcome between anterior colporrhaphy and trocar-guided transobturator anterior mesh. BJOG 2011;118:1518–1527.
Objective To compare anterior colporrhaphy with a trocar-guided transobturator mesh procedure (Avaulta® anterior).
Design Randomised, controlled trial.
Setting Three teaching hospitals.
Population Women with a symptomatic cystocele at least stage II requiring primary surgical correction.
Methods A total of 125 women were assessed at baseline and 1-year follow up. A sacrospinous hysteropexy or posterior colporrhaphy was performed when indicated.
Main outcome measures The primary outcome was the difference in anatomical cure (defined as Pelvic Organ Prolapse-Quantification <stage II cystocele). Secondary outcomes were complications, self-reported urogenital symptom severity, and quality of life, as measured with validated questionnaires.
Results In all, 64 women were allocated to the anterior colporrhaphy group and 61 to the mesh group; 58/64 women versus 56/61 completed 12 months of follow-up analysis. Compared with the anterior colporrhaphy group, the mesh reduced the risk of anatomical failure at 12 months follow up from 59 to 9% (risk reduction 50.3%, 95% CI 35.5–65.1). Only three (5%) re-operations for anatomical failure in the anterior colporrhaphy group were performed versus 0% in the mesh group. Functional outcome improved significantly at 12 months on almost all domains, with similar results between groups. Mesh exposure occurred in two (4%) women. Baseline dyspareunia disappeared significantly more often after an anterior colporrhaphy (80%) than in the mesh group (20%). There was a trend towards more de novo dyspareunia in the mesh group (15% versus 9%).
Conclusions Primary cystocele repair with trocar-guided transobturator mesh resulted in a statistically significant better anatomical outcome compared with the anterior colporrhaphy. However, functional outcome was similar between groups.
