Native Tissue Repairs for Pelvic Organ Prolapse

Effect of mesh anchoring technique in uterine prolapse repair surgery: A finite element analysis

The female pelvic cavity involves muscles, ligaments, endopelvic fasciae and multiple organs where different pathologies may occur, namely the pelvic organ prolapse (POP). The synthetic implants are used for the reconstructive surgery of POP, but severe complications associated with their use have been reported, mainly related to their mechanical properties (e.g., implant stiffness) and microstructure. In this study, we mimicked a transvaginal reconstructive surgery to repair the apical ligaments (uterosacral ligaments (USLs) and cardinal ligaments (CLs)), by modeling, their impairment (90% and 50%) and/or total rupture. The implants to reinforce/replace these ligaments were built based on literature specifications and their mechanical properties were obtained through uniaxial tensile tests. The main aim of this study was to simulate the effect of mesh anchoring technique (simple stich and continuous stitch), and compare the displacement magnitude of the pelvic tissues, during Valsalva maneuver. The absence/presence of the synthetic implant was simulated when total rupture of the CLs and USLs occurs, causing a variation of the vaginal displacement (9% for the CLs and 27% for the USLs). Additionally, the simulations showed that there was a variation of the supero-inferior displacement of the vaginal wall between different anchoring techniques (simple stich and continuous stitch) being approximately of 10% for the simulation USLs and CLs implant. The computational simulation was able to mimic the biomechanical behavior of the USLs and CLs, in response to different anchoring techniques, which can be help improving the outcomes of the prolapse surgery.

Ultrasound analysis of the effect of second delivery on pelvic floor function in Chinese women

In our study, patients who had a second delivery were categorised into the following 4 groups. Pelvic floor ultrasound data were compared during the 6th week after the second delivery. The incidence of cystoceles was highest in group A and lowest in group D. In addition, groups A and B had a higher rate of rectoceles or perineum descent. Similarly, the areas of the levator hiatus were higher in Groups A and B during Valsalva manoeuvres. The area of the levator hiatus from the resting state to the Valsalva manoeuvre effect had the greatest change in Group A. A comparison of the PR thickening rates among the four groups did not reveal significant differences. All second delivery methods can cause varying degrees of pelvic organ prolapse and decreased pelvic floor function; however, vaginal delivery as the second delivery mode may have a more significant effect in Chinese women.Impact StatementWhat is already known on this subject? Different modes of delivery have significantly different effects on female pelvic floor function. Pregnancy beyond 35 weeks of gestation has an effect on female pelvic floor function, irrespective of the mode of delivery.What do the results of this study add? This study analysed the impact of different delivery modes on Chinese female pelvic floor function. Parous women who underwent different modes of second delivery all demonstrated different degrees of pelvic organ prolapse, as well as pelvic floor function decline.What are the implications of these findings for clinical practice and/or further research? Our study will provide basic research of Chinese female pelvic floor function after a second delivery, which will be of clinical significance around the world, as well as in China. China will keep promoting further delivery as the aging population is increasing. If the developing countries want to promote the second delivery around the women, they have basic research and data to instruct the females.

The Influence of Vaginal Native Tissue Repair (VNTR) on Various Aspects of Quality of Life in Women with Symptomatic Pelvic Organ Prolapse-A Prospective Cohort Study

Pelvic organ prolapse (POP) and the associated functional disorders are a major epidemiological problem that compromises the quality of life (QoL). The aim of this study was to assess the impact of lower urinary tract symptoms (LUTS) related to POP and vaginal native tissue repair (VNTR) on QoL. Two hundred patients with symptomatic POP were stratified into four groups according to the dominant storage phase function disorders: Urgency; stress urinary incontinence (SUI); mixed urinary incontinence (MUI), and without clinically significant symptoms from lower urinary tract (LUT). They underwent VNTR from January 2018 to February 2019. After 12 months, the QoL was assessed by the Prolapse Quality of Life (P-QoL) and visual analogue scale (VAS) questionnaires. The data were analyzed with Statistica package version 12.0 (StatSoft, Krakow, Poland), using the Kalmogorow–Smirnoff, Shapiro–Wilk W and the one-way analysis of variance with post hoc Tukey tests. The results of P-QoL showed significant improvement (p < 0.05) in all the study groups in most domains assessed before surgery and 12 months after surgery. Significant improvements in all the symptoms assessed by the VAS scale results were found in groups Urgency and MUI. The LUTS questionnaire revealed significant improvement in all voiding and post voiding symptoms in these groups. VNTR effectively eliminated LUTS and significantly improved the patients’ QoL associated with POP.

The Influence of Vaginal Native Tissues Pelvic Floor Reconstructive Surgery in Patients with Symptomatic Pelvic Organ Prolapse on Preexisting Storage Lower Urinary Tract Symptoms (LUTS)

The aim of this study was to assess the effectiveness of vaginal native tissue repair (VNTR) on preexisting Lower Urinary Tract Symptoms (LUTS) in women with symptomatic pelvic organ prolapse (POP). Two hundred patients who underwent VNTR for symptomatic POP from January 2018 to February 2019 were followed up for 6 months. All patients underwent VNTR, but in the posterior compartment, the rectovaginal fascia was reconnected to the uterosacral ligaments and additionally sutured to the iliococcygeus fascia and muscle. To assess the severity and change in storage phase LUTS before and after surgery, all participants were asked to complete 3 questionnaires: the International Consultation on Incontinence Questionnaire- Short Form (ICIQ-SF), Urogenital Distress Inventory-6 (UDI-6), and Incontinence Impact Questionnaire-7 (IIQ-7). The data were assessed with Statistica package version 12.0, using Kalmogorow–Smirnoff, W Shapiro–Wilk tests. Furthermore, one-way analysis of variance was applied with post-hoc Tukey test. The study results indicate that the majority of patients with advanced POP suffered from various LUTS. Among storage symptoms, the occurrence of urinary incontinence (UI) and urgency decreased significantly after surgery. Moreover, ICIQ-SF, UDI-6, and IIQ-7 results showed statistically significant improvement in the impact of UI on the quality of life (QoL) in the vast majority of patients after surgery. VNTR is an effective way to treat not only anatomical, but also functional problems in such patients.

Vaginal Native Tissue Repair for Posterior Compartment Prolapse: Long-Term Analysis of Sexual Function and Quality of Life in 151 Patients

OBJECTIVES

The aim of this study was to assess the effectiveness and safety of vaginal native tissue repair for symptomatic rectocele and to evaluate the impact on quality of life (QoL) and sexual function.

METHODS

One hundred fifty-one patients affected by rectocele stage II or higher according to the Pelvic Organ Prolapse Quantification System were enrolled. Patients underwent vaginal native tissue repair. Postoperative assessments consisted in a clinical examination and assessment of posterior compartment symptoms and defecatory dysfunctions. These were conducted 1, 12, and 60 months after surgery. Patients completed the Prolapse Quality-of-Life questionnaire, the Pelvic Floor Disability Index, the Pelvic Floor Impact Questionnaire, and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form.

RESULTS

The median follow-up was 64 (60-72) months. The median operative time was 55 (37-127) minutes, and the median postoperative hospital stay was 2 (2-4) days. No intraoperative complications occurred. At median follow-up, an objective cure rate of 88.2% was observed. Seventeen patients (11.3%) showed recurrent posterior vaginal descent stage II or higher. Defecatory dysfunctions, vaginal digitation, and vaginal bulge decreased significantly. The change of values of the Prolapse Quality-of-Life, Pelvic Floor Disability Index, and Pelvic Floor Impact Questionnaire questionnaires has shown a significant improvement in the QoL after surgery. The percentage of patients regularly practicing sexual activity increased, and dyspareunia decreased after treatment.

CONCLUSIONS

Vaginal native tissue repair is a safe and effective procedure for symptomatic rectocele, with a low rate of complications, and improves pelvic organ prolapse-related symptoms, QoL, and sexual function.

Effectiveness, quality of life and sexual functions in women with anterior compartment prolapse treated by native tissue repair

Anterior compartment defect is the most common pelvic organ prolapse. It is defined as the descent of the bladder into the anterior vaginal wall. The etiology is multifactorial and the main risk factors are vaginal delivery and conditions associated with increased abdominal strain. Aging is significantly associated with the prevalence and severity of pelvic organ prolapse. Treatment may be conservative or surgical according to symptoms, prolapse degree and not forgetting both patient and doctor preferences. The aim of this work is to identify the most efficient surgical treatment of cystocele and its recurrences. There are two different surgical approaches for the treatment of cystocele: traditional repair and mesh repair. Prosthetic treatment gives higher anatomical success rate but traditional anterior repair has less complication demonstrating a lower risk of reoperation. Surgical treatment in general improves both the quality of life (QoL) and the sexual function. We carried out a research on the impact of the anterior defect before and after native tissue surgery on QoL and sexual function. The efficacy and complications of the treatment were also assessed.
