Background
Pelvic organ prolapse (POP) is greatly affecting the quality of life (QOL) of women. There are some surgical techniques for POP repair, for example, transvaginal mesh surgery (TVM), laparoscopic sacrocolpopexy (LSC), and robot-assisted sacrocolpopexy (RSC). In the United States and Europe, the number of TVM has rapidly decreased since 2011 due to complications and safety concerns and has shifted to LSC/RSC. In Japan, RSC has increased after the insurance coverage of RSC in 2020. Therefore, we compared the surgical outcomes of TVM and RSC in POP surgery.
Methods
We retrospectively collected POP surgery underwent TVM or RSC at our hospital and compared the operative time, blood loss, postoperative hospital stay, postoperative complications, and preoperative and postoperative stress urinary incontinence (SUI) of two groups. Preoperative and postoperative SUI were classified into 3 groups: “improved preoperative SUI”, “persistent preoperative SUI” and “de novo SUI”, which occurred for the first time in patients with no preoperative SUI, and compared incidence rate. The Mann–Whitney U test and Fisher’s exact test were used to compare the two groups, and P < 0.05 was considered statistically significant.
Results
From August 2011 to July 2021, 76 POP surgery was performed and they were classified into two groups: TVM group (n = 39) and RSC group (n = 37). There was no difference in patient age and BMI between the TVM and RSC groups. The median of operative time was 78.0 vs. 111.0 min (p = 0.06), blood loss was 20.0 ml vs. 5.0 ml (p < 0.05), and postoperative hospital stay was 4.0 days vs. 3.0 days (p < 0.05), with less blood loss and shorter postoperative hospital stay in the RSC group. There was no difference in postoperative complications between the TVM and RSC groups (17.9% vs. 16.2%, p = 1.00). De novo SUI was 25.6% vs. 5.4% (p < 0.05) in the TVM and RSC groups, of which 23.1% vs. 5.4% (p < 0.05) occurred within 3 months of surgery.
Conclusion
RSC is more beneficial and less invasive for patients with pelvic organ prolapse than TVM. In addition, de novo SUI as postoperative complication of RSC was lower than of TVM.
