The impact of vaginal hysterectomy and uterosacral ligament suspension on vaginal elasticity and sexual function.

Hysterectomy for benign indications has profound effects on both anatomical and physiological pelvic floor and vaginal properties. Vaginal tactile imaging (VTI) enables the quantification of pelvic floor and vaginal biomechanical properties; this enables objective evaluation of various pelvic floor functions. The purposes of this study were to evaluate via VTI, the changes in vaginal elasticity, mobility and strength, before and after hysterectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) and high utero-sacral ligament suspension (USLS); and to assess associations with sexual function. The objective of the current study was to evaluate the effect of these procedures on vaginal elasticity and sexual function. This prospective cohort study included women who underwent hysterectomy by vNOTES and USLS for the treatment of pelvic organ prolapse (POP). All the women underwent both pre- and postoperative VTI and sexual function evaluation. Vaginal elasticity and wall mobility, and the contraction strength and tone of levator muscles, were measured prior to and 6 months following surgery using VTI. A total of 23 women, mean age 56.5 years, with stage 3-4 POP participated. Vaginal elasticity increased from 27.3 ± 8.8 to 34.8 ± 12 (P < 0.05) and Female Sexual Function Index (FSFI) scores increased from 22.17 ± 1.62 to 28.66 ± 1.51 (P < 0.05). No correlation was observed between these results. A statistically significant decrease in the mobility of the anterior vaginal wall was demonstrated, from 7.98 ± 10.6 to 0.83 ± 7.5 (P < 0.0001). VTI showed improvements in vaginal elasticity, mobility and FSFI scores following hysterectomy and POP repair performed by vNOTES.
