Sacrospinous ligament fixation with uterine preservation reduces the risk of anatomical recurrence in pelvic organ prolapse

Objectives This study investigated the effectiveness of sacrospinous ligament fixation (SSLF) and whether uterine preservation reduces the anatomical recurrence rate. Methods The medical records of 82 patients who received SSLF in a single medical center were reviewed retrospectively. Anatomical recurrence was defined as Pelvic Organ Prolapse-Quantification stage 2 or higher in any compartment. The primary outcome was intergroup analysis for uterine preservation and concomitant hysterectomy patients. The secondary outcomes were anatomical recurrence risk factors and the incidence of adverse events. Propensity score matching (PSM) was used to adjust for demographic differences between groups. Results The anatomical recurrence rate was 19.5%, and the retreatment rate was 11.0% (mean follow-up duration: 22.9 months). Cystocele was the most common recurrent compartment (17.1%). The uterine preservation group (n = 66) was younger, had lower parity, and had fewer stage 3 to 4 cystoceles and uterine prolapses than the concomitant hysterectomy group (n = 16). Shorter operation times (99.4 minutes vs 153.7 minutes, P = .002) and lower anatomical recurrence rates (11.5% vs 45.5%, P = .039) were found in the uterine preservation group before and after PSM. Previous pelvic organ prolapse surgery (hazard ratio 3.14) and concomitant hysterectomy (hazard ratio 4.08) were identified as risk factors for anatomical recurrence. The most common adverse event was buttock pain (14.6%), which resolved spontaneously within 4 weeks. Conclusions SSLF is an effective surgical method using native tissue for pelvic reconstruction. Compared with concomitant hysterectomy, SSLF with uterine preservation reduces the anatomical recurrence rate.

Automated summary

This study demonstrated that sacrospinous ligament fixation (SSLF) is an effective surgical method for pelvic reconstruction using native tissue. Compared to concomitant hysterectomy, SSLF with uterine preservation reduces the anatomical recurrence rate, with shorter operation times and lower recurrence rates.
