ObjectiveThe aim of the study was to investigate whether uterine weight as measured by ultrasound uterine volume has an impact on the success rate of sacrospinous hysteropexy for uterine descent, as well as evaluate whether the failure rate varies between premenopausal and postmenopausal women. Study design: this investigation was designed as a prospective cohort study. Patients and methods A total of 30 premenopausal and 30 postmenopausal patients with uterine prolapse stage 2-4 were enrolled in this study during the period from February 2009 to October 2013. All patients underwent vaginal sacrospinous hysteropexy at Fayoum University Teaching Hospital, Egypt. Fifty-six patients were seen 1 year postoperatively and were evaluated for uterine descent according to the classification of the International Continence Society. The primary measures were to evaluate the recurrence rate among the two groups and also to evaluate the uterine volume as a factor for recurrence. Secondary outcomes were surgical complications and hospital stay.
ResultsThe failure rate of sacrospinous hysteropexy was higher among premenopausal patients than among postmenopausal patients (28.6 vs. 7.1%; P = 0.036). A binary logistic regression of effect of uterine volume showed a significant effect of uterine volume on the recurrence rate of uterine prolapse, with increased recurrence among patients with larger uterine volume (odds ratio = 0.989). There was no statistical difference between the two groups regarding complications and hospital stay.
ConclusionAlthough vaginal sacrospinous hysteropexy is an effective and safe method of surgical treatment for uterine prolapse, the success rate is higher among postmenopausal women. Further, the success rate is higher among those with lower ultrasonographically determined uterine volumes. Therefore, surgeons should consider these findings when deciding the treatment options for their patients with uterine descent.Receiver operator characteristic curve for uterine volume as a prognostic indicator for the recurrence rate of uterine descent.
