Current surgical management of pelvic organ prolapse: Strategies for the improvement of surgical outcomes

3D Observation of Pelvic Organs with Dynamic MRI Segmentation: A Bridge Toward Patient-Specific Models

INTRODUCTION AND HYPOTHESIS

Female pelvic organ prolapses are common, but their treatment is challenging. Notably, diagnosis and understanding of these troubles remain incomplete. Tridimensional observations of displacement and deformation of the pelvic organs during a strain could support a better understanding and help to develop comprehensive tools for preoperative planning.

METHODS

The present feasibility study evaluates tridimensional dynamic MRI in 12 healthy volunteers. Tridimensional acquisitions were approximated using five intersecting slices, each recorded twice per second. MRI was performed during rest and strain, with intrarectal and intravaginal contrast gel. Subject-specific dynamic 3D models were built for each volunteer through segmentation.

RESULTS

For each volunteer, pelvic organs could be segmented in three dimensions with a rate of acquisition of two cycles per second on five slices, allowing for a fluid observation of displacements and deformations during strain. Manual segmentation of a full strain required 2 h and 33 min on average. The upper limit of the rectum and the pelvic floor were the most difficult structures to identify. This technique is limited by its time-consuming manual segmentation, which impedes its implantation for routine clinical use. This method must be tried in patients with pelvic organ prolapse.

CONCLUSIONS

This multi-planar acquisition technique applied during a dynamic MRI allows for observation of displacement and deformations of pelvic organs during a strain.

Effect of Vaginal Microecological Alterations on Female Pelvic Organ Prolapse

INTRODUCTION AND HYPOTHESIS

The objective was to investigate the correlation between endogenous vaginal microecological alterations and female pelvic organ prolapse (POP).

METHODS

Patients who underwent vaginal hysterectomy were retrospectively analyzed as the POP group (n = 30) and the non-POP group (n = 30). The vaginal microbial metabolites and enzyme levels were tested using the dry chemoenzymatic method. The mRNA and protein expression were tested using real-time quantitative PCR and immunohistochemistry. SPSS version 25.0 and GraphPad Prism 8.0 were performed for statistical analysis.

RESULTS

Compared with the non-POP group, the vaginal pH, H2O2 positivity and leukocyte esterase positivity were higher in patients with POP (all p < 0.05). Further analysis showed that patients with pelvic organ prolapse quantification (POP-Q) stage IV had higher rates of vaginal pH, H2O2 positivity and leukocyte esterase positivity than those with POP-Q stage III. Additionally, the mRNA expression of decorin (DCN), transforming growth factor beta 1 (TGF-β1), and matrix metalloproteinase-3 (MMP-3) in uterosacral ligament tissues were higher, whereas collagen I and III were lower. Similarly, the positive expression of MMP-3 in uterosacral ligament tissue was significantly upregulated in the POP group compared with the non-POP group (p = 0.035), whereas collagen I (p = 0.004) and collagen III (p = 0.019) in uterosacral ligament tissue were significantly downregulated in the POP group. Correlation analysis revealed that there was a significant correlation between vaginal microecology and collagen metabolism. In addition, MMP-3 correlated negatively with collagen I and collagen III (p = 0.002, r = -0.533; p = 0.002, r = -0.534 respectively), whereas collagen I correlated positively with collagen III (p = 0.001, r = 0.578).

CONCLUSIONS

Vaginal microecological dysbiosis affects the occurrence of female POP, which could be considered a novel therapeutic option.

Quality-of-life improvements in patients after various surgical treatments for pelvic organ prolapse

OBJECTIVE

To compare the improvements in quality of life of patients with pelvic organ prolapse (POP) treated using various surgical methods.

MATERIALS AND METHODS

The PUBMED, MEDLINE and Cochrane Library online databases were searched using the keywords "pelvic organ prolapse", "surgery", "PFDI-20" and "PFIQ-7" for articles published from January 2010 to December 2022 that included quality-of-life scores before and after surgery.

RESULTS

Forty-nine articles were include. The mean postoperative PFDI-20 and PFIQ-7 scores decreased by 67.50% and 76.98%, respectively, compared with those before surgery. In 76.9% of patients, this change did not decrease with increased postoperative time. The improvement rate in PFDI-20 scores after colpocleisis did not differ statistically from that after sacrocolpopexy and was significantly higher than that after other procedures. The improvement rate in PFIQ-7 scores after colpocleisis did not statistically differ from that after high uterosacral ligament suspension and was significantly higher than that after other procedures. The improvement rate in PFDI-20 scores after transvaginal mesh-based repair (TVM) did not significantly differ from that after sacrospinous ligament fixation and was significantly lower than that after other procedures except traditional vaginal wall repair. The improvement rate in PFIQ-7 scores after TVM did not significantly differ from that after new procedures and was significantly lower than that after other procedures.

CONCLUSIONS

Surgical treatment can significantly improve the quality of life of patients with POP. Colpocleisis may offer more advantages than those of other surgical procedures, and improvement was lower after TVM than after other procedures.

The effect of concomitant hysterectomy on complications following pelvic organ prolapse surgery

PURPOSE

Pelvic organ prolapse (POP) surgery is performed with and without concomitant hysterectomy depending on a variety of factors. The objective was to compare 30-day major complications following POP surgery with and without concomitant hysterectomy.

METHODS

This was a retrospective cohort study using the National Surgical Quality Improvement Program (NSQIP) multicenter database to compare 30-day complications using Current Procedural Terminology (CPT) codes for POP with or without concomitant hysterectomy. Patients were grouped by procedure: Vaginal prolapse repair (VAGINAL), minimally invasive sacrocolpopexy (MISC), and open abdominal sacrocolpopexy (OASC). 30-day postoperative complications and other relevant data were evaluated in patients who underwent concomitant hysterectomy compared to those who did not. Multivariable logistic regression models assessed the association of concomitant hysterectomy on 30-day major complications stratified by surgical approach.

RESULTS

60,201 women undergoing POP surgery comprised our cohort. Within 30 days of surgery, there were 1722 major complications in 1432 patients (2.4%). Prolapse surgery alone had a significantly lower overall complication rate than with concomitant hysterectomy (1.95% vs 2.81%; p < .001). Multivariable analysis revealed odds of complications following POP surgery was higher among women who underwent concomitant hysterectomy compared to those who did not have hysterectomy in VAGINAL (OR 1.53, 95% CI 1.36-1.72), OASC (OR 2.70, 95% CI 1.69-4.33), and overall (OR 1.46, 95% CI 1.31-1.62), but not in MISC (OR 0.99, 95% CI 0.67-1.46.) CONCLUSION: Concomitant hysterectomy at the time of pelvic organ prolapse (POP) surgery increases the risk of 30-day postoperative complications in comparison to prolapse surgery alone in our overall cohort.

Pelvic organ prolapse: Women's experiences of Accessing Care & Recommendations for improvement

Up to 50% of women will develop pelvic organ prolapse (POP) over their lifetime. Symptoms include pain, bulge, urinary, bowel and sexual symptoms affecting all aspects of a woman's life.Many women with POP symptoms present initially to primary care settings. Research has shown these interactions are often unsatisfactory, with women reporting their health care professional (HCP) trivialized their symptoms or appeared to have poor knowledge about pelvic floor dysfunction (PFD).Aim The aim of this qualitative study was to explore experiences of younger women seeking treatment for POP and their recommendations for improvements.Methods Ethics approval was obtained (LS-21-01-Carroll-Ful). Women with POP were recruited from an online support group (n = 930 members). Inclusion criteria: adult women, diagnosed with POP and aware of their POP stage. Following informed consent, a demographic questionnaire, interview questions and the Central Sensitization Inventory (CSI) were forwarded. Semi-structured zoom audio-recorded interviews were conducted. Thematic analysis was undertaken; transcripts coded, and themes identified.Results Fourteen women aged 32-41, parity 1-3, with POP Grade 1-3 participated. Many women reported HCPs as dismissive or not appreciative of the impact of their condition. Others described interactions with HCPs who they felt listened, understood the impact of their POP, gave simple explanations, a positive prognosis and outlined a realistic treatment plan.Current antenatal education, post-partum care and primary HCP screening for PFD were identified by women as deficient. Many highlighted delays in accessing specialist care for POP. Women made several recommendations for improvements to the current model of care.Conclusions Increased focus on person-centred care, particularly emotional support, information and education may improve younger women's experiences when seeking care for POP.

Characteristics and outcomes of patients with pelvic organ prolapse: an analysis of data from Mulago National Referral Hospital from 2007-2016

INTRODUCTION

Pelvic organ prolapse (POP) is associated with negative physical, social, psychological, and sexual experiences. There is paucity of data in low and middle income countries like Uganda. The purpose of this study was to describe clinical characteristics and outcomes of patients undergoing surgery for POP from 2007 to 2016.

METHODS

The study was conducted at Mulago National Referral Hospital from 2014 to 2016. We conducted a retrospective review of the urogynecology surgical records using a standardized medical record abstraction form. Data of 222 POP patients were abstracted and managed using REDCap. Analysis was performed using Stata statistical software, v14.

RESULTS

The mean participant age and parity was 57 years and 7 respectively. Ninety four percent of participants presented with a mass protruding from the vagina, 38% with uterine prolapse and 32% with cystocoele. Anaemia and hypertension were common comorbidities. Women underwent a variety of surgery types, and 35% experienced persistent pain post-operatively. At hospital discharge, 83% had achieved either complete resolution or improvement in their condition.

CONCLUSIONS

Measures encouraging presentation for care as soon as symptoms are experienced and reduction of total fertility rate will be beneficial. Patients with POP should be routinely screened for anaemia and hypertension.

Abdominal Sacrohysteropexy using Proline mesh versus Mersilene tape in apical prolapse: A randomized clinical trial

IMPORTANCE

uterine preservation is increasingly a common demand in surgical management of pelvic organ prolapse. Using Proline mesh in surgical repair of prolapse may have negative drawbacks.

OBJECTIVE

compare between using Polyproline mesh and Mersilene tape in abdominal Sacrohysteropexy repairing apical prolapse stage ӀӀ or more.

STUDY DESIGN

This RCT study was conducted at the Department of Obstetrics and Gynecology (Menoufia and Ain Shams university hospitals, Egypt). Eligible population included women planned Sacrohysteropexy for uterine prolapse ≥ stage 2 assigned to two groups: Mesh group (n = 38), underwent Sacrohysteropexy with polyproline mesh, and Tape group (n = 38), underwent Sacrohysteropexy using Mersilene tape.

RESULTS

High statistically significant difference between TAPE group and MESH group concerning hysteropexy time was 50.4 min in TAPE group vs 90.6 min in MESH group (p < 0.001), need for post operative analgesia was14 in TAPE group vs 27 in MESH group (p < 0.005). The mean hospital stay was 2.8 days in TAPE group vs 5.2days in MESH group (p < 0.001).

CONCLUSIONS

Using Mersilene tape in Sacrohysteropexy is a safe alternative to Polyproline Mesh with comparable efficacy with less complications. Tape is easier as it needs less dissection area for sacral fixation so less injury incidence.

Magnitude of Symptomatic Pelvic Floor Dysfunction and Associated Factors Amongst Women in Western Ethiopia: A Cross-Sectional Study

The goal of this research was to determine the extent of pelvic floor dysfunction and the factors that contribute to it. The study design was community-focused and cross-sectional, and participants were chosen using a systematic random sampling technique. For data entry and cleansing, we used EPI data version 3.1 software, and for analysis, we used Statistical Package for the Social Sciences version 26. The 95% confidence interval was predicted, and the factor with a significant level less than 0.05 was chosen for multivariate logistic regression analysis. The overall Magnitude of pelvic floor dysfunction was 37.7% [(95% confidence interval (31.7-42.5)]. The most common type of pelvic floor dysfunction is overactive bladder, which was reported by 135 of all participants. Pelvic organ prolapse accounted for 92 (30.4%) of all cases, and 4 factors were found to be significantly associated with pelvic floor dysfunction. In this study, age 55 years [(AOR = 2.1; 95% CI: (1.52-6.42)], heavy labor work for more than 10 years [(AOR = 3.21; 95% CI: (1.86-5.72) grand-multipara, and being menopause [(AOR = 4.03; 95% CI: (2.20-8.27)] were linked to symptoms of pelvic floor dysfunction. The magnitude of pelvic floor dysfunction in this study was slightly higher than in Ethiopian studies. Pelvic floor dysfunction has been linked to heavy load lifting, low socioeconomic status, recurrent vaginal deliveries, chronic cough, and menopause. Screening and treatment of pelvic floor disorders should be prioritized in collaboration with regional and zonal health departments.

Cosmetic gynecology-An emerging field for the dermatologist

INTRODUCTION

Cosmetic gynecology is an expanding field with a steep rise in awareness and demand for procedures to enhance the aesthetic appearance of female genitalia.

AIM

This article aims to provide an overview of aesthetic gynecology for a practicing dermatologist.

METHODS

A study conducted in India showed a rising trend in the demand of aesthetic vaginal procedures from 3.9% in 2012 to 28.97% in 2015.

CONCLUSION

Several aesthetic modalities such as peels, platelet rich plasma, and energy-based devices and surgical modalities have been in use, though serious evidence for efficacy of many of these procedures is lacking.

Pregnancy outcomes after abdominal sacrocervicopexy

INTRODUCTION AND HYPOTHESIS

Various methods are used in pelvic organ prolapse (POP) surgery. Organ-preserving methods are gaining importance and popularity. Although the success rates of abdominal sacrocervicopexy, which is one of these methods, are known, data on pregnancy outcomes are insufficient. The aim of this study was to investigate pregnancy outcomes after abdominal sacrocervicopexy.

METHODS

This study included 72 patients with a diagnosis of POP who underwent abdominal sacrocervicopexy with monofilament polypropylene mesh in Diyarbakir Gazi Yaşargil Training and Research Hospital between 2008 and 2016. Anterior and posterior colporrhaphy operations were performed. Postoperatively, these patients were followed up for a mean of 29.68 ± 6.55 (20-49) months. Pregnancy and recurrence outcomes of those who became pregnant were recorded and analyzed.

RESULTS

On average, pregnancies occurred 23.2 (18-30) months after the operation. During follow-up, eight patients became pregnant and gave birth without any issues or complications. One had a normal vaginal delivery, and seven gave birth by cesarean section. One of the pregnant women had a twin pregnancy. When 24 patients who underwent bilateral tubal ligation and postmenopausal (n = 2) were excluded, the pregnancy rate was found to be 17.3%. The weeks of the deliveries were 35 weeks (twin pregnancy), 38 weeks (n = 2), 39 weeks (n = 3), and 40 weeks (n = 1), for an average of 38.5 weeks.

CONCLUSIONS

Eight patients who had undergone abdominal sacrocervicopexy had healthy pregnancies and deliveries.

Quality of Life Following Pelvic Organ Prolapse Treatments in Women: A Systematic Review and Meta-Analysis

Introduction: Quality of life (QoL) improvement is one of the main outcomes in the management of pelvic organ prolapse as a chronic illness in women. This systematic review aimed to investigate the impact of surgical or pessary treatment for pelvic organ prolapse (POP) on quality of life. Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was applied. Electronic databases, including PubMed, Scopus, and Web of Science, were searched for original articles that evaluated the QoL before and after surgical interventions or pessary in pelvic organ prolapse from 1 January 2012 until 30 June 2022 with a combination of proper keywords. Included studies were categorized based on interventions, and they were tabulated to summarize the results. Results: Overall, 587 citations were retrieved. Of these, 76 articles were found eligible for final review. Overall, three categories of intervention were identified: vaginal surgeries (47 studies), abdominal surgeries (18 studies), and pessary intervention (11 studies). Almost all interventions were associated with improved quality of life. The results of the meta-analysis showed a significant association between the employment of surgical approach techniques (including vaginal and abdominal surgeries) and the quality of life (Pelvic Floor Distress Inventory (PFDI) (MD: −48.08, 95% CI: −62.34 to −33.77, p-value < 0.01), Pelvic Floor Impact Questionnaire (PFIQ) (MD: −33.41, 95% CI: −43.48 to −23.34, p < 0.01)) and sexual activity of patients with pelvic organ prolapse (Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ) (MD: 4.84, 95% CI: 1.75 to 7.92, p < 0.01)). Furthermore, narrative synthesis for studies investigating the effect of the pessary approach showed a positive association between the use of this instrument and improvement in the quality of life and sexual activity. Conclusions: The results of our study revealed a significant improvement in the women’s quality of life following abdominal and vaginal reconstructive surgery. The use of pessary was also associated with increased patient quality of life.

Contemporary Clinical Research in the Management of Pelvic Organ Prolapse in the United States: A Systematic Review

IMPORTANCE

Pelvic organ prolapse (POP) can cause bothersome symptoms that negatively affect quality of life. Management strategies include observation, conservative management, and surgery.

OBJECTIVE

The purpose of this study was to evaluate the current focus of research in POP.

STUDY DESIGN

We queried clinicaltrials.gov, a registry of clinical research studies maintained by the U.S. National Library of Medicine, for active, recruiting, and enrolling studies involving POP.

RESULTS

A total of 104 unique clinical trials were included for analysis. Investigators most commonly specialized in obstetrics and gynecology (obstetrician-gynecologists [ob-gyns]; n = 66, 57.9%); urologists numbered 5 (4.4%). The most common subspecialty was urogynecology (n = 46, 40.4%). Seventy-six percent of clinical research involved surgical intervention. The second most common field of research was diagnostic evaluation of POP (8.4%). Only 12.1% of clinical research focused on conservative measures, and 2.8% investigated medications. Objective outcome measures were used more often than subjective or mixed measures (42.3%, 22.3%, and 32.7%, respectively). The most common outcome measure was Pelvic Organ Prolapse Quantification (14.5%), followed by the mixed measure, "composite success" (8.7%).

CONCLUSIONS

Urologists are less involved in POP research than ob-gyns. Urogynecologists from either background are most involved. Most clinical research involves surgical management of POP, despite the fact that less than 20% of women pursue surgical correction. Despite dubious concordance with quality of life, objective outcome measures are used more often than subjective or mixed measures to assess severity of POP. Clinical research in POP should be directed to better align with the needs and preferences of patients.

Prevalence and surgical outcomes of stage 3 and 4 pelvic organs prolapse in Jimma university medical center, south west Ethiopia

Background

Pelvic organ prolapse (POP) affects about half of the women and affects their quality of life. The current study is, therefore, aimed at determining the prevalence and surgical outcomes of severe stage POP at Jimma University medical center from November 2016 to May 2018.

Method

A Hospital-based cross-sectional study was conducted on all patients with stage 3 and 4 POP, who were admitted, and had surgery. Data were collected from the patient’s chart, and logbooks, which were filled up from entry till her discharge. A Simplified POPQ(S-POPQ) was used to stage the prolapse at admission, at discharge, and three months follow-ups.

Results

Among 92 patients who were analyzed, POP accounts for 10.6% of all gynecologic admissions, and 43.8% of all gynecologic surgeries. The mean age of patients is 46 (± 12) years, and nearly 34% of the patients had stage 3 and 66% had stage 4 POP. Based on the type of prolapse, 93.5% of patients had stage 3 and more anterior vaginal wall prolapse (AVWP) and apical prolapse, while 57.6% had stage 3 or more posterior vaginal wall prolapse.

Out of 72 patients who had anterior colporrhaphy, 58.7% had anterior colporrhaphy with colposuspension. Out of 83 patients who had apical suspension, 48.2%, 39.8%, and 12% had uterosacral, sacrospinous, and Richardson respectively.

Ninety-seven patients had stage 0 or 1 POP at discharge while 90% of 20 patients who returned for follow-up at three months had stage 0 or 1 POP. Eight patients had surgery-related complications; bladder injury, urinary retention, Hemorrhage during SSLF, and rectal injury.

Conclusion

The prevalence of pelvic organ prolapse is high and the majority of patients presented with advanced-stage pelvic organ prolapse, with a long duration of symptoms and associated problems. The surgical techniques used have resulted in a high immediate success rate of 97% and 90% at discharge and three months follow up respectively. Therefore, awareness creation activities are important to facilitate an early presentation for treatment to improve the quality of life and the current surgical technique; native tissue vaginal repair (NTVR), being practiced in the setup has had better success.

Outcomes of vaginal hysterectomy combined with anterior and posterior colporrhaphy for pelvic organ prolapse: a single center retrospective study

Objective

To evaluate the efficacy of vaginal hysterectomy combined with anterior and posterior colporrhaphy (VH APR) for the management of pelvic organ prolapse (POP).

Methods

A total of 610 patients with POP who underwent VH APR from January 2010 to June 2019 at Asan Medical Center were included in this study. We analyzed the patient characteristics and surgical outcomes. In addition, we compared the POP quantification system (POP-Q) pre- and postoperatively at 2 weeks, 3 months, and 1 year, and analyzed the risk factors for recurrence.

Results

The mean age of the patients was 65.5±7.6 years. The most common preoperative POP-Q stage was stage 2 (60.8%), followed by stage 3 (35.9%). Complications were identified during surgery in 1.6% of the patients. The most common postoperative complication (6.4%) was voiding difficulty. All POP-Q scores significantly decreased at 1 year after surgery (P<0.0001). The recurrence rate was 9.6%, and most recurrences (77.5%) occurred in the anterior compartment. An advanced stage of preoperative POP was a risk factor for recurrence (stage 3 or 4 vs. stage 1 or 2; odds ratio [OR], 5.337, 95% confidence interval [CI], 2.58–11.036, P<0.0001). Only two patients underwent surgical correction for POP recurrence, and most of the remaining patients did not undergo further treatment for prolapse.

Conclusion

VH APR is a safe and effective surgical procedure for POP, with a low recurrence rate. In addition, advanced preoperative stage was the only risk factor for recurrent POP.

The role of hydrodissection in native tissue repair of anterior vaginal wall defects

AIMS

A variety of surgical techniques are available for vaginal prolapse repair, indicating a lack of consensus. A debate regarding the utility of hydrodissection for splitting the surgical plane of the vaginal wall exists. The aim of this study is to evaluate the impact of hydrodissection in anterior colporrhaphy (AC).

MATERIALS

Patients undergoing primary AC were randomly assigned to an approach with (study group) versus without (control group) hydrodissection. Five surgeons performed both techniques, and the trimmed vaginal tissue was retrieved for histological analysis. Two pathologists, blinded to the surgical approach, evaluated the presence of a loose connective tissue at the surgical dissection plane (controversially deemed 'fascia', as explained in this article). In addition, we compared the operative time, pain score and haemoglobin levels. After statistical analysis, data were presented using percentile, and statistical significance was tested using the χ² and Fisher's exact tests.

RESULTS

Forty-six patients underwent primary elective AC, with 23 patients in each, the study and control groups. The groups were comparable regarding age (study group 60.33 ± 11.95 years and control group 59.86 ± 12.04, P = 0.90), menopausal status (study group 17 (73.9%) and control group 15 (68.2%), P = 0.67) and other characteristics. We found no difference in sample characteristics between the two groups. Connective tissue was found in only 13.6% (n = 3) of patients after hydrodissection and in 27.3% (n = 6) of patients without hydrodissection (P = 0.46). The hydrodissection group had significantly less bleeding than the control group (ΔHB 0.66 ± 0.66 vs 1.21 ± 0.84, P = 0.05).

CONCLUSIONS

After hydrodissection, less bleeding was noted without compromise the surgical planes.

Transperineal pelvic floor ultrasound for analyzing the outcomes of pelvic floor surgery for the treatment of anterior compartment prolapse: A comparative study of transvaginal mesh and native-tissue repair

OBJECTIVE

To compare the outcomes of transvaginal mesh (TVM) and native-tissue repair (NTR) for the repair of anterior compartment prolapse.

METHODS

This retrospective study involved 90 patients with anterior compartment prolapse who underwent pelvic organ prolapse surgery between January 2018 and October 2020. A TVM was used to treat 53 patients and 37 underwent NTR. All patients underwent a standardized interview, clinical examination, and four-dimensional pelvic floor ultrasound (PFUS) before and after the surgery. The primary outcome was anatomic recurrence evaluated by ultrasonic parameters. The secondary outcomes were subjective recurrence and complications.

RESULTS

Subjective recurrence was 9.43% (5/53) for TVM and 16.22% (6/37) for NTR (P = .522). Significant recurrence of prolapse on ultrasound occurred in five patients (9.43%) after TVM and 12 (32.43%) after NTR; there was a significant difference between the TVM and NTR groups (P = .006). In the TVM group, the mesh was visible on ultrasound in each patient. The mesh exposure rate was 1.89% (1/53). The postoperative hiatal area reduction in the TVM group, compared with the NTR group, was statistically significant (5.55 ± 4.71 cm² vs 3.09 ± 5.61 cm² , P = .027). The incidence of de novo stress urinary incontinence was higher in the TVM group (20.75% vs 2.70%, P = .03). After surgery, there were significant differences between the two groups based on bladder descent (12.02 ± 8.64 mm vs 22.41 ± 13.95 mm, P = .000) and urethral rotation angle (25.26 ± 13.92° vs 40.27 ± 23.72°, P = .001).

CONCLUSION

PFUS is effective for evaluating postoperative outcomes. TVM facilitates a better anatomic cure than NTR for anterior compartment prolapse.

The Comparison of Outcomes of Transvaginal Mesh Surgery with and without Midline Fascial Plication for the Treatment of Anterior Vaginal Prolapse: A Randomized Controlled Trial

The aim of this study was to compare the clinical outcomes of transvaginal mesh (TVM) surgery with and without midline fascial plication for anterior prolapse repair. This is a prospective randomized trial in a teaching hospital. This study compared patients with anterior vaginal wall prolapse (POP-Q Ba > −1) who were randomly assigned to either transvaginal mesh (TVM, Avaulta Solo^TM, CR Bard. Inc., Covington, GA, USA polypropylene mesh delivery system) (group A, n = 32) or TVM with concomitant midline fascial plication (group B, n = 32). The outcomes of anatomy correction and life quality were evaluated using a pelvic organ prolapse quantification system and questionnaires. Sixty-four patients were included from January 2011 through April 2014 in this study. Group A had a mean age of 63.7 years and a body mass index (BMI) of 25.4 kg/m². Group B had a mean age of 62.9 years and a BMI of 25.4. The mean follow-up duration was 18.6 months (range 12–50). At the 12-month follow-up, anatomic recurrence was higher in Group A (5/31, 16.1%) than in Group B (1/30, 3.3%) but without statistical significance (p = 0.19). Improvements in symptoms and quality of life were not significantly different between the two groups. Mesh extrusion was detected in three of 61 patients (4.9%): two from group A (6.7%) and one from Group B (3.2%). TVM with concomitant midline fascia repair for anterior vaginal prolapse had a comparable anterior support and mesh exposure rate compared with TVM alone. Trial Registration: IRB-B09904021

Effectiveness and Safety of Posterior Vaginal Repair with Single-Incision, Ultralightweight, Monofilament Propylene Mesh: First Evidence from a Case Series with Short-Term Results

Objective

The use of transvaginal mesh is controversial, and over time, multiple surgical methods for the treatment of posterior vaginal prolapse (PVP) have been proposed including different surgical approaches and techniques. To date, no clear conclusion has been reached about the use of mesh for reinforcing transvaginal posterior repair. The aim of this study was to evaluate the feasibility, safety, and effectiveness of a novel, ultralightweight mesh for the treatment of PVP.

Methods

We performed a single-center, prospective observational study on consecutive patients referred for primary or recurrent, symptomatic stage II PVP (according to the international Pelvic Organ Prolapse Quantification System) from April 2017 to September 2018. In all patients, transvaginal posterior repair was augmented with a single-incision, isoelastic polypropylene mesh. Data about the postoperative outcomes were collected until December 2019.

Results

A total number of 15 patients were included. The median follow-up after surgery was 18 months (IQR = 14). Surgery was completed in all cases without complications. Regarding the anatomical outcomes (as measured according to POP-q classification), a significant improvement was observed in terms of Bp, D, and C (p < 0.05). The functional outcomes were significantly ameliorated after surgery, with a reduction of bulge symptom, stypsis, incomplete evacuation, and excessive staining (p < 0.05). The quality of life was significantly improved in the majority of patients (p < 0.05). Median patients' satisfaction rate was 100% (IQR = 22.5%). Neither early nor late postoperative complications occurred.

Conclusions

Single-incision, ultralightweight polypropylene meshes were safe and highly effective in the treatment of PVP. As our study has some limitations, further large, controlled studies are needed.

Erosion of soft tissue by polypropylene mesh products

Surgical mesh products made from polypropylene (PP) have been extensively used in the treatment of stress urinary incontinence, pelvic organ prolapse and other conditions. Since the onset of the use of such implants, major complications have been reported. Mesh erosion, where neighbouring tissues are worn from the rubbing of mesh, occurs in a significant number of cases. However, there is still a lack in literature exploring the mechanics of this phenomenon. In this study, a purpose-built apparatus was used to generate erosion in soft tissue (porcine muscle) through the application of a force and a reciprocating action. Four different commercial products were tested, all made from knitted PP fibres: Monarc™ Gynecare™ and Obtryx™ slings and Sutulene™ mesh sheet material. A PP suture and three PP sheets with different edge roughness were also tested. Large differences were found in the erosion rates. Significantly, we found that meshes in which the edge had been formed using heat to cause partial melting gave much higher rates of erosion than mechanically cut edges. Heat-formed edges tended to retain their shape whilst mechanically cut edges degraded by unravelling. Several features of the mesh edge appear to be significant, including roughness, flexibility and the tendency to degrade. Constant load (non-reciprocating) tests were also carried out, revealing that creep can also cause erosion. These findings have significance for the design of surgical mesh products to minimise their adverse effects.

A novel antibacterial biomaterial mesh coated by chitosan and tigecycline for pelvic floor repair and its biological performance

The biomaterials composed of mammalian extracellular matrix (ECM) have a great potential in pelvic floor tissue repair and functional reconstruction. However, bacterial infection does cause great damage to the repair function of biomaterials which is the major problem in clinical utilization. Therefore, the development of biological materials with antimicrobial effect is of great clinical significance for pelvic floor repair. Chitosan/tigecycline (CS/TGC) antibacterial biofilm was prepared by coating CS/TGC nanoparticles on mammalian-derived ECM. Infrared spectroscopy, scanning electron microscopy, bacteriostasis circle assay and static dialysis methods were used to characterize the membrane. MTS assay kit and DAPI fluorescence staining were used to evaluate cytotoxicity and cell adhesion. The biocompatibility was assessed by subabdominal implantation model in goats. Subcutaneous antimicrobial test in rabbit back was used to evaluate the antimicrobial and repairing effects on the infected wounds in vivo. Infrared spectroscopy showed that the composite coating had been successfully modified. The antibacterial membrane retained the main structure of ECM multilayer fibers. In vitro release of biomaterials showed sustained release and stability. In vivo studies showed that the antibacterial biological membrane had low cytotoxicity, fast degradation, good compatibility, anti-infection and excellent repair ability.

Pessary evaluation for genital prolapse treatment: From acceptance to successful fitting

AIMS

To determine the percentage of women with symptomatic pelvic organ prolapse who opted for pessary and had a successful pessary fitting trial; to identify the most commonly used size of pessary for stage of prolapse; and to identify risk factors associated with unsuccessful fitting.

METHODS

We conducted a prospective cohort study of women with symptoms of genital prolapse referred to a public hospital tertiary care clinic (2013-2019). We used ring and ring with support pessaries for fittings. We collected patient demographics, pelvic organ prolapse quantification, size of pessary used and evaluated factors associated with pessary fittings. We defined unsuccessful fit as failure to continue pessary use at 4 weeks post fitting trial. We used Mann-Whitney and χ² tests to compare variables between groups of successfully and unsuccessfully fitted. Using logistic regression, we built a prediction model for unsuccessful fit.

RESULTS

All 170 women with symptomatic prolapse referred to our clinic accepted to undergo a pessary fitting. More than 70% (n = 124/72.9%) were successfully at 4 weeks. We used an average of 1.7 pessaries (range: 1-6) per patient to identify the best-fitting pessary and #2, 5, 3, 7, and 4 were the sizes commonly used (78.2%). Women with body mass index ≥30 kg/m² (odds ratio [OR]: 4.74; 95% confidence interval [CI], 1.98-11.32; P < .001), total vaginal length <7.5 cm (OR: 3.78; 95% CI, 1.98-11.32; P < .001), and sexually active women (OR: 2.26; 95% CI, 1.04-4.91; P = .035) were associated with increased unsuccessful fitting.

CONCLUSION

The vaginal pessary proved to be an excellent choice, with high acceptance and successful fitting rates.

Robotic Sacrocolpopexy for Treatment of Apical Compartment Prolapse

Abdominal sacrocolpopexy is the gold-standard treatment for apical compartment prolapse, as it is more effective and durable than the transvaginal approach. In the current era of minimally invasive surgery, laparoscopic sacrocolpopexy techniques have been described, but have not gained popularity due to their complexity and steep learning curves. To overcome this problem, robotic sacrocolpopexy was introduced, and has shown equivalent outcomes and safety compared to open and laparoscopic sacrocolpopexy based on findings that have been accumulated over 15 years.
