Abstract

Introduction and hypothesis: Hysterectomy is frequently performed and associated with increased risk of subsequent genital prolapse including vaginal vault prolapse. Ipsilateral uterosacral ligament suspension (IUSLS) and sacrospinous ligament fixation (SSLF) are two commonly performed surgical techniques to treat vaginal vault prolapse. There is no consensus on the ideal operation technique. The aim of this study was to compare IUSLS and SSLF to treat vaginal vault prolapse based on the number of repeat surgeries. Methods: Previously hysterectomized patients operated on with IUSLS or SSLF in Denmark in 2010–2016 were included in this nationwide register-based cohort study and followed until June 2017. Data were obtained from Danish National Databases, to which reporting is mandatory by law, entailing high validity and completeness of data. Data were analyzed using Cox proportional hazard regression analysis adjusted for age, preoperative prolapse stage, smoking, BMI, and previous prolapse surgery. Results: In total, 744 patients were included; 384 underwent IUSLS while 360 underwent SSLF. After 5 years, 6.5% of patients operated on with IUSLS and 21.8% operated on with SSLF had a repeat surgery in the apical compartment and 12.4% and 30.6% in any compartment, respectively. The risk of repeat surgery was 4.8 times higher after SSLF compared to IUSLS [confidence interval (CI): 2.7–8.4] in the apical compartment and 2.4 times higher (CI: 1.2–5.1) in the anterior compartment. No difference was seen in the posterior compartment. Conclusions: This study finds significantly higher numbers of repeat surgeries after SSLF compared to after IUSLS in a Danish nationwide cohort.
