Analysis of risk factors associated with surgical failure of sacrospinous suspension for uterine or vaginal vault prolapse

The goal of this study was to analyze the potential risk factors determining surgical failure after sacrospinous suspension for uterine or vaginal vault prolapse. Each woman underwent a detailed history taking and a vaginal examination before treatment. Follow-up evaluations were at immediate post-operation, 1 week, 1 to 3 months, 6 months, 9 months, and annually after the operation. The surgical failure rate (27/168) following sacrospinous suspension was 16.1%. Using multivariable logistic regression, women with the presence of C or D point stage I at immediate post-operation were a significant risk factor for surgical failure after sacrospinous suspension (odds ratio, 35.34; 95% confidence interval, 8.75–162.75; p < 0.001). The success rate during the 18-month follow-up decreased significantly in women with the presence of C or D point stage I at immediate post-operation than stage 0. Although the sample size of women with symptomatic uterine or vaginal vault prolapse is small, impaired correction of anatomic defects is a significant risk factor for surgical failure of sacrospinous suspension.
