Avulsion of puborectalis muscle and other risk factors for cystocele recurrence: a 2-year follow-up study

Abstract

Introduction and hypothesisThis study aimed to determine the relationship of recurrent cystocele with avulsion of puborectalis muscle and other risk factors.MethodsIn this prospective observational cohort study, 245 women undergoing anterior colporrhaphy were invited for a 2-year follow-up visit consisting of a questionnaire, physical examination, and translabial 3D ultrasonography. Women with and without recurrent cystocele were compared to identify recurrence risk factors.ResultsOf the 245 women, 156 agreed to the follow-up visit (63.7%). Objective recurrence rate was 80 of 156 (51.3%). Seventeen of the 156 (10.9%) reported subjective recurrence. Risk factors for anatomical recurrence were complete avulsion of puborectalis muscle (OR, 2.4; 95% CI, 1.3, 4.7), advanced preoperative stage (OR, 2.0; 95% CI, 1.0, 4.1), family history of prolapse (OR, 2.4; 95% CI, 1.2, 4.9), and sacrospinous fixation (OR, 6.5; 95% CI, 2.0, 21.2).ConclusionsRisk factors for anatomical cystocele recurrence after anterior colporrhaphy were complete avulsion of puborectalis muscle, advanced preoperative stage, family history of prolapse, and sacrospinous fixation.
