Modified extraperitoneal uterosacral ligament suspension for prevention of vault prolapse after vaginal hysterectomy

Introduction and hypothesisDuring vaginal hysterectomy, extraperitoneal uterosacral ligament suspension (ULS) bites can be taken before removing the uterus. We evaluated this modified extraperitoneal ULS for vault prolapse prevention.MethodsStudy period was 3.5 years. Fifty-one women with third- and fourth-degree prolapse were enrolled. An inverted V incision was made on the anterior vaginal wall and continued as a semicircular incision on the posterior vaginal wall. Lateral vaginal mucosa was pushed up to expose the cardinal-uterosacral ligament complex. The first ULS suture, using polypropylene no. 1, was taken in the upper-most exposed area of the uterosacral ligament. The second suture, using polyglactin no. 1 or 0, was taken 0.5-1cm below the first suture. During placement of both sutures, traction on the cervix was maintained. The cardinal-uterosacral ligament complex was clamped, dissected, and ligated 1cm below the second suture. Vaginal hysterectomy was completed. Ends of the ULS suture were fastened to the vault via vesicovaginal and rectovaginal septum using polypropylene within and polyglactin outside vaginal mucosa.ResultsProlapse stage was 3 in 42 cases and 4 in nine. Duration of operation ranged from 60 to 120min. Blood loss was 100-300ml. During follow-up (average 2.3years) four (8.3%), cases had stage 1 pelvic organ prolapse (POP), three were lost to follow-up, and 44 (91.6%) had no POP.ConclusionsUsing the cervix as a traction device is a good option when performing extraperitoneal ULS during vaginal hysterectomy to prevent vault prolapse.
