Uterosacral ligament vaginal vault suspension: anatomy, outcome and surgical considerations

Laparoscopic uterosacral ligament suspension: a systematic review and meta-analysis of safety and durability

Introduction

Pelvic organ prolapse (POP) is a widespread condition affecting from 40% to 60% of women. Reconstructive vaginal surgeries are the most commonly performed procedures to treat POP. Among those, uterosacral ligament suspension (USLS), which is usually performed transvaginally, preserves pelvic statics and dynamics and appears to be an effective method. Laparoscopic USLS is a valid alternative to vaginal approach, and the aim of our review is to confirm its safety and feasibility and to compare clinical outcomes among the procedures.

Materials and methods

Following the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, we systematically searched the PubMed and Scopus databases in December 2022. We made no restriction on the publication year nor on the country. Data about POP-Q recurrence rate (RR), intraoperative and postoperative complications (graded according to Clavien-Dindo classification), readmission rate, and reoperation rate were collected and analyzed. We used comparative studies for meta-analysis.

Results

A total of nine studies fulfilled inclusion criteria: two articles were non-comparative retrospective observational studies, three more articles were comparative studies where laparoscopic USLS was confronted with other surgical techniques (only data of laparoscopic USLS were analyzed), and four were comparative retrospective cohort studies between laparoscopic and vaginal USLS procedures. The comparative studies were enrolled in meta-analysis. Patients were analyzed concerning perioperative risks and the risk of recurrence. The meta-analysis highlighted that there was no clear inferiority of one technique over the other.

Discussion

Laparoscopic USLS is a technique with a low complication rate and low recurrence rate. Indeed, laparoscopic procedure allows better identification of anatomical landmarks and access to retroperitoneum. Moreover, efficacy over time and durability of Laparoscopic (LPS) USLS was also observed. However, these data should be weighed in light of the length of follow-up, which was in a very short range. Further, focused and prospective studies will be necessary to confirm this finding.

Minimally invasive meshless and minimal dissection ligament fixation system for apical organ prolapse procedures: A 4-year prospective follow up study

OBJECTIVE

EnPlace™ (formerly named NeuGuide™) is a minimally invasive meshless anchoring system for pelvic organ prolapse (POP) repair designed to provide centro-apical pelvic floor support. We present a 4-year prospective follow up evaluation of this repair system.

METHODS

This was a single-center longitudinal prospective study of women with advanced POP who underwent pelvic floor apical repair using EnPlace™ with at least 4 years of follow-up. The primary outcome was surgical success defined as anatomical success, no symptoms of vaginal bulging and no need for re-treatment. A standardized validated questionnaire to assess symptom burden was used.

RESULTS

Fifteen women were enrolled in the study. Two patients were lost to follow-up. The median follow-up was 51 months (range 42-57) with a surgical success rate of 92.3%. One patient (7.7%) reported symptoms of vaginal vault prolapse and underwent a repeated prolapse surgery. Using the UDI-6 questionnaire, an improvement in all domains was seen.

CONCLUSION

The 4-year prospective follow up suggests that apical repair using the EnPlace™ device may be considered safe and effective for sacrospinous ligament fixation with a sustainable long-term success. This procedure is a minimally invasive meshless addition to pelvic surgeon's armamentarium.

Clinical outcomes and uroflowmetry assessment in patients with apical prolapse after laparoscopic uterosacral ligament suspension

OBJECTIVE

The aim was to evaluate the voiding function and voiding dysfunction 3 months after laparoscopic uterosacral ligament suspension (LUSLS). We identified risk factors for postoperative voiding dysfunction.

STUDY DESIGN

This retrospective study included 57 women with apical prolapse who underwent LUSLS with stage II or greater apical prolapse and without advanced anterior vaginal prolapse (stage III or IV). Data were collected from electronic medical records. Voiding function was assessed by uroflowmetry, PVR examination, and self-report questionnaires (the Pelvic Floor Distress Inventory-20 and the Urinary Impact Questionnaire) at baseline and 3 months after surgery. Voiding dysfunction was defined as an average flow rate (Qave)＜10 ml/s, a maximum flow rate (Qmax)＜15 ml/s, or a postvoid residual volume (PVR)＞50 ml. Statistical analyses were performed using paired-sample t tests, χ2 tests, and multivariate logistic regression.

RESULTS

Thirty-five percent of women suffered from voiding dysfunction preoperatively. Uroflowmetry parameters and PVR, objective symptoms including voiding difficulties, incomplete empty, frequency and urinary incontinence didn't show significant improvement postoperatively (all p＞0.05). Low Q_ave was identified as an independent risk factor of post voiding dysfunction (odds ratio, 0.558; 95 % CI, 0.324-0.963).

CONCLUSIONS

Approximately one-third of women suffering from apical prolapse without advanced anterior vaginal wall had evidence of voiding dysfunction preoperatively. LUSLS has no obvious effect on uroflowmetry parameters and clinical symptoms.

Traditional McCall culdoplasty compared to a modified McCall technique with double ligament suspension: anatomical and clinical outcomes

INTRODUCTION AND HYPOTHESIS

This study compared anatomical and clinical outcomes of traditional McCall culdoplasty versus a modified McCall technique with double ligament suspension (DLS).

METHODS

This retrospective study presents outcomes of 68 patients who underwent vaginal hysterectomy and vaginal suspension for apical prolapse ≥ stage II according to the POP-Q score system, at, between January 2016 and February 2018. In 34 women vaginal cuff suspension was obtained with traditional McCall culdoplasty (McCall group), while in 34 women we performed a modified McCall, which consists of a double ligament suspension (DLS group), suspending the vaginal cuff to uterosacral ligaments and also to adnexal peduncles. Primary outcome was prolapse recurrence ≥ stage II according to the POP-Q system. Fisher's, Mann-Whitney U and Student's t tests were used for statistical analysis.

RESULTS

There were no statistical differences among patients' preoperative characteristics, operative time, blood loss or postoperative complications. Follow-up mean duration was 23.2 ± 6.7 and 22.4 ± 8.7 months in the McCall and DLS group, respectively. Prolapse recurrence occurred in 11 (32.3%) women in the McCall group versus 2 (5.9%) women in the DLS group (p < 0.05): among them, 2 patients (5.9%) in the McCall group and 1 (2.9%) in the DLS group required further treatment. Total vaginal length was 6.1 ± 0.9 cm in the McCall group versus 6.9 ± 0.7 cm in the DLS group (p < 0.001). No statistical difference in quality of life assessment was observed.

CONCLUSIONS

DLS group patients had better anatomical outcomes and lower recurrence rates than McCall group patients, without increasing operative time or complications. A prospective study with more cases is needed to confirm our data.

Modified Extraperitoneal Uterosacral Ligament Suspension in Preventing Cuff Prolapse Risk after Vaginal Hysterectomy; 4 Clamp Method

Objectives: The extraperitoneal uterosacral ligament suspension (ULS) can be performed during the removal of the uterus in vaginal hysterectomy to prevent cuff prolapse. In this study, we evaluated the modified extraperitoneal ULS technique in terms of preventing cuff prolapse. Methods/Technique: Forty patients with second and third-stage uterine prolapse who were operated were included in the study. During routine vaginal hysterectomy procedure performed on patients, after sacrouterine ligaments which are the first-bites and uteroovarian and round ligaments which are the last-bites have been sutured and knotted, these ligaments were marked with 4-distinct clamps to make the right and left, upper and lower separation. After vaginal cuff was closed the sutures hanged by the clamps were ligated together, and the cuff tissue was stretched to the apical line. Results: According to the POP-Q classification, 22 patients with stage-2 and 18 patients with stage-3 prolapse were operated. During the 2-year follow-up; 4 patients could not be reached and were excluded from follow-up. Five of the remaining 36 patients (13.8%) found to have stage-1 cuff prolapse and 31 (86.1%) of patients had no prolapse. There was no significant decrease in postoperative vaginal length (p [Formula: see text] 0.05). The PISQ-12 sexual function scores was found similar before and after surgery (p [Formula: see text] 0.05). Conclusions: The extraperitoneal ULS is a successful method to prevent cuff prolapse after hysterectomy. Although there are various modified forms of this method, the modified ULS, which we have described as the 4-clamp method, seems to be successful in terms of initial results.

Outcomes of Transvaginal High Uterosacral Ligaments Suspension: Over 500-Patient Single-Center Study

BACKGROUND

Uterosacral ligament (USL) suspension is a safe and effective procedure in terms of anatomical, functional, and subjective outcomes for primary surgical treatment of prolapse.

OBJECTIVES

There has been a renewed interest toward native tissue prolapse repair by vaginal route because of low cost and lack of mesh-related complications. Uterosacral ligaments are considered safe, effective, and durable as suspending structures for primary surgical repair of the apical compartment. Our aim was to evaluate complications, anatomical, functional and subjective outcomes of high USL suspension for primary prolapse repair.

METHODS

Data of patients who underwent vaginal hysterectomy followed by high USL suspension for pelvic organ prolapse were retrospectively analyzed. Operative data, as well as complications, were recorded. Anatomical recurrence was defined as descent of any compartment stage II or greater according to the Pelvic Organ Prolapse Quantification system. Functional outcomes focused on urinary, bowel, and sexual dysfunctions. International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, Wexner, and Patient Global Impression of Improvement questionnaires were collected.

RESULTS

Data of 533 women were analyzed. Mean follow-up was 32 (SD, 19) months (dropout rate, 2.6%). Most frequent complication was ureteral kinking (2.6%). Total recurrence rate was 13.7%, with anterior compartment being the most frequent (9.4%), whereas reoperation for symptomatic prolapse recurrence was required in only 1% of patients. Improvement of urinary incontinence, voiding dysfunction, constipation, and dyspareunia was observed. Overall subjective satisfaction was high (Patient Global Impression of Improvement score, 1.3), ranging from "much improved" to "very much improved."

CONCLUSIONS

Uterosacral ligament suspension is a safe and effective procedure in primary surgical treatment of pelvic organ prolapse. Anatomical, functional, and subjective outcomes were very satisfactory, and reoperation rate for recurrence was only 1%.

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

INTRODUCTION AND HYPOTHESIS

During 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.

METHODS

Study 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 0.5-1 cm 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 1 cm 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.

RESULTS

Prolapse stage was 3 in 42 cases and 4 in nine. Duration of operation ranged from 60 to 120 min. Blood loss was 100-300 ml. During follow-up (average 2.3 years) four (8.3%), cases had stage 1 pelvic organ prolapse (POP), three were lost to follow-up, and 44 (91.6%) had no POP.

CONCLUSIONS

Using the cervix as a traction device is a good option when performing extraperitoneal ULS during vaginal hysterectomy to prevent vault prolapse.

Safety and short term outcomes of a new truly minimallyinvasive mesh-less and dissection-less anchoring system for pelvic organ prolapse apical repair

OBJECTIVE

To evaluate the safety and short term outcomes of a new, truly minimallyinvasive, mesh-less and dissection-less anchoring system for pelvic floor apical repair.

METHODS

A prospective study was conducted using the NeuGuide™ device system for pelvic floor apical repair. The primary effectiveness outcome was centro-apical pelvic floor prolapse by POP-Q after six months. The primary safety outcome was intra-operative, immediate (first 48 h) post-operative complications and adverse effects after six months. A standardized questionnaire (UDI-6) to assess quality of life at entry and during follow-up visits was used. Patients' six months-follow-up and evaluation are reported.

RESULTS

The mean age of the study population (n=10) was 63.8±12.0 years. All patients had a previous prolapse surgery. Five had a previous hysterectomy and two had stress urinary incontinence symptoms. During surgery six patients had a concurrent colporrhaphy. There was no injury to the bladder, rectum, pudendal nerves, or major pelvic vessels and no febrile morbidity was recorded. At six months, no cases of centro-apical recurrence were noted. Patients were satisfied with the procedure and had favorable quality of life scores. Using the UDI-6 questionnaire an improvement, in all domains was seen. Moreover, although the sample size was small, the improvement in urge and overflow incontinence related domains were demonstrated to be statistically significant.

CONCLUSIONS

This new NeuGuide™ device allows rapid and safe introduction of a suspending suture through the sacrospinous ligament and makes sacrospinous ligament fixation easy to perform, while avoiding dissection and mesh complications.

Introducing a true minimally invasive meshless and dissectionless anchoring system for pelvic organ prolapse repair

INTRODUCTION AND HYPOTHESIS

The objective was to demonstrate the biomechanical properties, feasibility, and potential advantages over conventional techniques of this new anchoring device, NeuGuide™.

METHODS

We evaluated the pull-out forces required to pull the NeuGuide™ anchor elements from a uniform porcine ligament and a cadaver ligament. We also evaluated the function of the NeuGuide™ and the characteristics of the device for the establishment of verification evidence ensuring the reliability and feasibility of the device. We also evaluated the safety and performance of the NeuGuide™ procedure in female cadavers by palpating the sacro-spinous ligament in real time. We assessed the ability to deploy and fixate the anchor to the sacro-spinous ligament and to stitch the sutures from both sides of the vaginal apex to the cervix, without damaging the surrounding structures.

RESULTS

All 12 anchors were inserted into the porcine ligament and the cadaver sacro-spinous ligaments successfully (mean pull-out force 34.13 ± 4.32 and 35.68 ± 9.28 respectively). None of the measured forces were below 20 N. No statistically significant difference was noted in the pull-out forces between the porcine and the cadavers (p = 0.60), between the two cadavers (p = 0.19) and between the right and left sacro-spinous ligaments. No abnormalities or malfunctions were noted in the functional performance of the device. Upon laparotomy, dissection of the cadavers revealed that the sacro-spinous ligaments were reached safely with no damage to the surrounding organs and tissues.

CONCLUSIONS

This novel anchoring device (NeuGuide™) is aimed at facilitating a durable, easy, and short procedure for sacro-spinous ligament fixation with hypothetically fewer operative complications.

Pectineal ligament suspension of prolapsed vaginal vault

OBJECTIVE

To report on a collective pectineal ligament suspension experience acquired over 12 years in India with 119 women who presented with prolapsed vaginal vault. The feasibility and effectiveness of the procedure was assessed for the open and laparoscopic routes.

METHODS

The prolapsed vaginal vault was suspended unilaterally to the pectineal ligament using polyester tape at 3 urban and 3 rural hospitals. The procedure was done through a Cherney incision in 104 women. In the remaining 15 women, it was done laparoscopically at a single urban center.

RESULTS

There were no intraoperative complications. The mean follow-up was 5.5 years (range, 0.5-12 years). Only 2 women had vaginal prolapse recurrence, at 3 and 5 years. Two had asymptomatic tape erosion, at 2 and 5 years, and a mild cystocele appeared in 5 women and a low rectocele in 4. However, none of these women required further vaginal surgery during their follow-up period.

CONCLUSION

The present study demonstrates the long-term safety and effectiveness of pectineal ligament suspension for vaginal vault prolapse by the open and the laparoscopic routes. As it was done by surgeons of varying experience at centers with varying resources, the procedure can be readily mastered by any gynecologic surgeon.

Normal vulvovaginal, perineal, and pelvic anatomy with reconstructive considerations

A thorough insight into the female genital anatomy is crucial for understanding and performing pelvic reconstructive procedures. The intimate relationship between the genitalia and the muscles, ligaments, and fascia that provide support is complex, but critical to restore during surgery for correction of prolapse or aesthetic reasons. The external female genitalia include the mons pubis, labia majora and minora, clitoris, vestibule with glands, perineal body, and the muscles and fascia surrounding these structures. Through the perineal membrane and the perineal body, these superficial vulvar structures are structurally related to the deep pelvic muscle levator ani with its fascia. The levator ani forms the pelvic floor with the coccygeus muscle and provides vital support to all the pelvic organs and stability to the perineum. The internal female genital organs include the vagina, cervix, uterus, tubes, and ovaries with their visceral fascia. The visceral fascia also called the endopelvic fascia, surrounds the pelvic organs and connects them to the pelvic walls. It is continuous with the paraurethral and paravaginal fascia, which is attached to the perineal membrane. Thus, the internal and external genitalia are closely related to the muscles and fascia, and work as one functioning unit.

Midline uterosacral plication anterior colporrhaphy combo (MUSPACC): preliminary surgical report

INTRODUCTION AND HYPOTHESIS

the objective of this study is to examine the surgical safety and early efficacy of the midline uterosacral (ligament) plication anterior colporrhaphy (MUSPACC) procedure.

METHODS

a retrospective review of the perioperative data of 41 women who had undergone an MUSPACC procedure without any other vaginal vault supportive procedure was performed.

RESULTS

the MUSPACC procedure can be performed comfortably through a single midline anterior vaginal wall incision, providing concomitant levels 1 and 2 support at anterior colporrhaphy. The procedure is safe and relatively quick (median 23 min) with consistent access to the intermediate section of the uterosacral ligament. Blood loss is generally minimal to small. Dissection is relatively limited. The ureters (2 cm or more lateral) are not deemed to be at risk. Short-term anatomical results are promising. There was no significant change in vaginal length.

CONCLUSIONS

the MUSPACC procedure is safe, relatively quick, and free of significant bleeding. It provides concomitant levels 1 and 2 vaginal support.

Clinical outcome of transvaginal sacrospinous fixation with the Veronikis ligature carrier in genital prolapse

OBJECTIVE

To evaluate the clinical outcome of sacrospinous fixation (SSF) using the Veronikis ligature carrier (VLC) for genital prolapse.

STUDY DESIGN

A retrospective longitudinal study was performed. From December 2003 through June 2008, SSF was performed in 76 patients using the VLC as part of their site-specific reconstructive pelvic surgery. All patients were followed up postoperatively at 6 weeks, 3 months, 6 months, 12 months, and annually thereafter.

RESULTS

The median operative time of SSF was 34min. It took less than 5min to introduce two sutures through the ligament using the VLC. Four patients (5.3%) had recurrent vaginal vault descent at 3-8 months, and received SSF again. Three patients had recurrent stage 1 cystocele at 6-12 months, but did not require further surgery.

CONCLUSION

The VLC allowed effective introduction of the suspending suture through the sacrospinous ligament and might be considered an important surgical component in the treatment of severe genital prolapse.
