Comparison of sexual function outcomes after vNOTES and laparoscopic tubal sterilization.

OBJECTIVE

To compare postoperative sexual function outcomes following vaginal natural orifice transluminal endoscopic surgery (vNOTES) and laparoscopic tubal sterilization (LTS).

MATERIAL AND

METHODS

This retrospective comparative cohort analysis included 64 women with prospectively collected routine clinical data who underwent permanent surgical sterilization using vNOTES (n = 31) or laparoscopy (n = 33). Dyspareunia VAS, QSES, and FSFI scores were assessed preoperatively and at 6 months. Six-month outcomes were compared using ANCOVA adjusted for the corresponding baseline scores. Adjusted mean differences, 95% confidence intervals, and partial eta squared (partial η2) were reported.

RESULTS

After adjustment for baseline scores, the 6-month dyspareunia VAS score was significantly higher in the vNOTES group than in the LTS group (AMD, 0.44; 95% CI, 0.22 to 0.66; unadjusted p < 0.001; Holm-adjusted p < 0.002; partial η2 = 0.210). No significant differences were observed in the primary outcome, total FSFI (AMD, -1.00; 95% CI, -2.70 to 0.70; p = 0.240), or in QSES (AMD, -0.40; 95% CI, -2.10 to 1.30; Holm-adjusted p = 0.640). Among the exploratory FSFI domains, only satisfaction remained significantly lower in the vNOTES group after Holm correction (AMD, -0.39; 95% CI, -0.61 to -0.17; Holm-adjusted p < 0.006). The unadjusted difference in lubrication did not remain significant after correction (Holm-adjusted p = 0.055).

CONCLUSION

vNOTES was associated with higher dyspareunia scores and lower satisfaction-domain scores at 6 months; however, no significant between-group differences were observed in total FSFI or QSES scores. These findings should be interpreted cautiously because of the retrospective, nonrandomized design and small sample size.
