Complications of Transvaginal Mesh for Pelvic Organ Prolapse and Stress Urinary Incontinence: Tips for Prevention, Recognition, and Management

[Management of complications in reconstructive pelvic floor surgery]

Reconstructive pelvic floor surgery offers a wide range of surgical options for treating urinary incontinence, organ prolapse and other pelvic floor disorders. The aim is always to choose the safest and most effective procedure to improve the quality of life of those affected. In addition to expertise in making the appropriate diagnosis and surgical experience, knowledge of how to deal with complications is always essential. When categorising complications, a distinction is made between early and late complications, intraoperative and postoperative complications, and general and procedure-specific complications. If complications arise, conservative and surgical treatment options should be known. The starting point here is adequate diagnostics, which may include basic examinations, sonography, endoscopy and imaging techniques. The aim is to be able to accurately assess the extent of the complication in order to choose the appropriate therapy-preferably conservative methods. Particular challenges in the management of complications in reconstructive pelvic floor surgery are posed by complications with foreign materials. Surgical complication management can be very complex, requires a high level of surgical expertise and may also require an interdisciplinary approach. Gaining expertise in managing complications, whether conservative or surgical methods, can be challenging, especially when aiming to avoid causing those complications yourself. Thus, the best complication management is preventive: knowing the patient well, diagnosing the disease precisely and knowing one's own limits!

3D-Printed Silk Fibroin Mesh with Guidance of Directional Cell Growth for Treating Pelvic Organ Prolapse

Damages to the supportive structure of the pelvic floor frequently result in pelvic organ prolapse (POP), which diminishes the quality of life. Surgical repair typically involves mesh implantation to reinforce the weakened tissues. However, the commonly used polypropylene (PP) mesh can lead to severe complications due to the mechanical mismatch of the mesh with the pelvic tissues. In this study, 3D-printed silk fibroin (SF) meshes are developed and optimized through cryogenic 3D printing followed by post-stretching treatment to enhance mechanical properties and biocompatibility for POP repair. Rheological analysis shows that the 30 wt % SF-based ink exhibited a zero shear viscosity of 1838 Pa·s and shear-thinning behavior, ensuring smooth extrusion during 3D printing. During the cryogenic incubation following 3D printing, self-assembly of SF occurs with the formation of β-sheet structures, leading to robust constructs with good shape fidelity. The post-stretching treatment further improves SF chain alignment and fibrilization, resulting in enhanced mechanical performance and a microstrip surface that promotes cell attachment, alignment, and differentiation. The SF mesh with a post-stretching ratio of 150% shows an ultimate tensile strength of 1.49 ± 0.14 MPa, an elongation at break of 104 ± 13%, and a Young's modulus of 5.0 ± 0.1 MPa at a hydrated condition, matching the properties of soft pelvic tissues. In vitro studies show that post-stretched SF meshes facilitated better cell alignment and myogenic differentiation than PP meshes. In vivo assessments demonstrate enhanced biocompatibility of the SF meshes, with better cellular infiltration and tissue integration than PP meshes in the long-term implantation, showing potential as a safe, effective alternative to traditional synthetic meshes for POP repair and other clinical applications.

Mid-term outcomes of moderate-severe cystocele repairing with autologous fascia lata harvested through a small incision

INTRODUCTION AND HYPOTHESIS

To investigate the mid-term outcomes of transvaginal repair for moderate-severe cystocele using autologous fascia lata harvested through a single small incision.

METHODS

Between February and October 2022, 35 patients with moderate to severe cystocele undergoing transvaginal repair with autologous fascia lata were included. Patient demographics and perioperative data were collected, with follow-ups through outpatient visits or phone calls. Patients were evaluated by subjective perception of vaginal bulging, physical examination, Pelvic Floor Distress Inventory (PFDI-20) Questionnaire, patient satisfaction, Patient Global Impression of Improvement (PGI-I) scores, regret rate, willingness to recommend, complications, and harvesting site issue.

RESULTS

The patient's mean age was 60.44 ± 6.01 years. Fascia lata harvesting took 32.92 ± 19.72 min, reconstruction surgery lasted 141.21 ± 37.89 min. Follow-up duration was 15.94 ± 2.46 months. 5.7% (2/35) of the patients reported a non-interfering vaginal bulge not requiring treatment. Objective recurrence rate was 4.26% (1/24, Aa or Ba>0) PFDI-20 was significantly improved (P < 0.0001). All 35 patients (100%) were highly satisfied, with PGI-I score very much improved or improved. No patient regretted. 97.14% (34/35) would recommend the procedure. One patient developed poor wound healing at the vaginal apex. One patient developed thromboembolic event. Harvest site: 2.86% (1/35) developed a non-bothersome thigh bulge, 17.14% (6/35) noted an impact on wound appearance, and 8.57% (3/35) reported mild paresthesia.

CONCLUSION

Autologous fascia lata for cystocele treatment shows promising mid-term outcomes, safely and effectively enhancing QoL with high satisfaction. Despite concerns about leg scarring, no patient regretted and would recommend the procedure. Long-term outcomes require larger follow-up studies.

Management of Complications of Prosthetic Mid-urethral Tape Surgery for Stress Urinary Incontinence in Women

OBJECTIVE

To propose guidelines for the management of complications of prosthetic mid-urethral tape surgery for stress urinary incontinence in women.

METHODS

These guidelines are based on an exhaustive literature review on retropubic and trans-obturator mid-urethral tape complications. The expert panel rated the level of evidence of each study, summarized literature for the treatment of each complication, and proposed guidelines.

RESULTS

Management of these complications is complex and the first treatment is crucial to offer the best functional result to the patient. We propose a standardized approach and guidelines for the management of complications to help physicians to early identify a surgical complication, offer adequate treatment for each complication and provide clear and appropriate information to patients. We detailed management of intraoperative complications as follows: bladder, urethral, vaginal, visceral, and vascular injury; short-term post-operative complications are the following: bleeding/hematoma, voiding dysfunction, pain, infection; and long-term post-operative complications are the following: chronic voiding dysfunction, de novo overactive bladder syndrome, chronic pain, dyspareunia, vaginal, bladder, and urethral tape erosion.

CONCLUSION

These guidelines may help physicians to improve management of prosthetic mid-urethral sling complications that may occur following stress urinary incontinence surgery.

Anterior Colporrhaphy and Paravaginal Repair for Anterior Compartment Prolapse: A Review

Pelvic organ prolapse, particularly in the anterior compartment, is a prevalent condition that significantly impacts women's quality of life. Two common surgical approaches for managing anterior vaginal wall prolapse are anterior colporrhaphy and paravaginal repair. Anterior colporrhaphy, a traditional technique, involves the plication of weakened fascial tissues to restore support to the bladder and anterior vaginal wall. Paravaginal repair addresses lateral detachment of the anterior vaginal wall by reattaching it to its supportive structures. This review aimed to compare the indications, techniques, and outcomes between these surgical methods, discussing their efficacy, recurrence rates, and complications. Although anterior colporrhaphy is widely used, paravaginal repair may offer superior results in specific cases, particularly those involving lateral defects. The review also explored the evolution of these techniques, the role of grafts and mesh, and the potential benefits of minimally invasive approaches such as laparoscopy and robotic surgery. The goal is to provide clinicians with comprehensive insights into choosing the appropriate surgical option based on individual patient anatomy and clinical presentation, thus optimizing outcomes and minimizing recurrence.

'I have no life and neither do the ones watching me suffer': women's experiences of transvaginal mesh implant surgery

Objective: Many women are affected by pelvic floor disorders, such as stress urinary incontinence and pelvic organ prolapse. In recent years, these disorders have been treated with transvaginal mesh implant surgeries involving the vaginal insertion of woven netting. We explored women's experiences of transvaginal mesh implant surgery through a biopsychosocial lens. Design: We analysed women's submissions to an Australian Parliament Senate Inquiry on transvaginal mesh implant surgery using thematic analysis. Main Outcome Methods: One-hundred and fifty-three publicly available submissions detailing women's experiences of transvaginal mesh implant surgery to an Australian Parliament Senate Inquiry were analysed. Adverse and positive accounts were eligible for inclusion. Results: We generated nine themes in three categories relating to the Biopsychosocial Model: Physical Health - comprising three themes; Psychological Health - comprising two themes; and Social Wellbeing - comprising four themes. Physical, psychological and social experiences interacted, resulting in reduced quality of life for women. Conclusion: Most women who made submissions to an Australian government inquiry about transvaginal mesh implant surgery described devastating impacts on physical, psychological, and social wellbeing. We provide recommendations to guide psychologists in assisting women with adverse transvaginal mesh-related outcomes. Further research should explore women's long-term experiences of the various transvaginal mesh procedures.

Harvest of large fascia lata autograft: Outcomes in 108 patients

PURPOSE

Due to the reclassification of transvaginal mesh as a high-risk device, there has been renewed interest in the use of fascia lata in pelvic floor reconstruction. Here we report our experience in 108 patients who underwent large fascia lata harvest for pelvic organ prolapse (POP) repair. Our primary objective was to highlight the postoperative morbidity of the large fascia lata harvest in patients who underwent POP repair using fascia lata autograft.

METHODS

Surgery involved harvesting a fascia lata graft through a small lateral upper thigh incision and was used for either autologous transvaginal POP repair or autologous sacrocolpopexy. To prevent seroma, a temporary Jackson-Pratt drain was intraoperatively placed and a mild compression wrap was applied to the area for 4-6 weeks postoperatively. Patient demographics were obtained preoperatively, while physical exam findings and postoperative outcomes related to the fascia lata harvest were collected at sequential follow up visits.

RESULTS

One-hundred eight patients underwent 111 large fascia lata harvests for either transvaginal or abdominal/robotic POP repair from July 2016 to January 2022. Mean follow-up was 19.6 months (range: 1-65) with 38 patients having 24 months or more of follow-up. Mean Visual Analog Pain (VAP) score was 1 (range: 0-10). Sixteen patients developed asymptomatic thigh bulges, 16 patients developed harvest site seromas (of which 14 resolved), and 59 patients experienced mild, non-bothersome paresthesia near the incision.

CONCLUSION

Large fascia lata harvest offers a robust autograft for transvaginal or transabdominal POP repair with minimal morbidity. Harvest site complications are minor and typically resolve with expectant management. This technique can be safely utilized in patients who desire graft-augmented repair of POP without the use of synthetic mesh, allograft, or xenograft.

Should endoscopic laser excision be offered as the first-line management for patients with eroded mesh? Outcomes of a systematic review of literature

PURPOSE OF REVIEW

Mesh erosions following previous synthetic sling/mesh surgery for stress urinary incontinence (SUI) have become increasingly common. This systematic review provides evidence for the role of laser excision as a first-line management in patients with eroded mesh.

RECENT FINDINGS

Fourteen articles (173 patients) were included for the final review. Among these, 138 patients (79.8%) were submitted to trans-urethral laser excision of eroded urethral/bladder mesh over a median time to presentation of 36.6 months. Over a median follow-up of 23.6 months, 88 (63.7%) reported a complete resolution, 32 (23.2%) reported persistence or recurrence of SUI and 17 (12.3%) presented with recurrent mesh erosion. The success rate after a single endoscopic procedure was 66.5, vs. 93.5% after additional endoscopic procedures, with only 9 (6.6%) requiring open surgical excision. Overall, there were seven (5.1%) postoperative complications including two urethrovaginal fistulas, two UTIs and haematuria each, and one case of urethral diverticulum.

SUMMARY

Laser excision of eroded mid-urethral slings into either the bladder or urethra is a challenging complication of minimally invasive incontinence surgery. Laser excision was able to achieve a good success rate with single or staged endoscopic procedure with a low risk of complication. It represents a valid first treatment option, although patients should be managed in mesh referral centres in collaboration with uro-gynaecology teams.

Trans-labial or introital ultrasounds for midurethral slings

Stress urinary incontinence is common in adult women. The use of introital or trans-labial ultrasound can help the surgeon (urologist or gynecologist) to better assess the type of incontinence the patient presents in order to guide him in the management of the patient. Often, surgical treatment with a mid-urethral sling (MSU) placement can be chosen in case of failure of non-invasive therapies (such as local estrogen or physical therapy) and if the clinical examination shows an urethral hypermobility. The use of ultrasound can help in this choice. Although rare, complications of MSU can sometimes cause disabling symptoms and be difficult to diagnose. Introital or trans-labial ltrasound can help diagnose them. The objective of this work was to describe the realization of ultrasound of stress urinary incontinence before or after the placement of a MSU, in order to make their realization easier for young surgeons which can use them in current practice.

Surgical treatment of advanced anterior wall and apical vaginal prolapse using the anchorless self-retaining support implant: long-term follow-up

INTRODUCTION AND HYPOTHESIS

Following health notification by the FDA in 2008 of serious complications with transvaginal mesh for anterior pelvic organ prolapse, there has been a return to native tissue repairs. Earlier work with a self-retaining support (SRS) implant showed a high anatomical success rate with minimal implant-related complications over a medium-term follow-up. It is proposed that post-implant complications are more a consequence of the method of mesh anchoring rather than the implant itself. Our system incorporates an ultralight mesh with a frame that provides level I, II, and III support without the need for fixation. The first long-term outcomes of SRS implantation are presented.

METHODS

A prospective multicenter trial was conducted using two consecutive identical protocols of the use of the SRS implant in women with symptomatic anterior compartment prolapse extending their follow-up to 36 months. Anatomical success (Pelvic Organ Prolapse Quantification stage 0 or 1 or a Ba ≤ -2) was recorded along with subjective success as defined by regular quality-of-life (PFDI-20 and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire) assessments.

RESULTS

Sixty-seven patients completed 36 months of follow-up. Mean Ba measurements improved from 3.1 (-1 to 6) cm to -2.8 (-1 to -3) cm and C point from 0.4 (-8 to 6) cm to -6.9 (-10 cm to 1) cm. accumulating to a significant anatomical success rate of 94.3%. Subjective success based on question #3 of the PFDI-20, analyzed for the index surgical compartment, reached 95.7%. Post-operative complications included 2 cases of urinary retention, 1 minor frame exposure, 1 case of delayed voiding dysfunction, and 2 cases of de novo stress urinary incontinence. Untreated pre-operative second-degree Bp measurements had increased in 27% at follow-up.

CONCLUSION

The long-term outcome of the SRS implant shows an excellent subjective and objective success with minimal risk of complications or need for reintervention.

Total Autologous Fascia Lata Sacrocolpopexy for Treatment of Pelvic Organ Prolapse: Experience in Thirty-Four Patients

OBJECTIVE

To develop a technique for open/robotic sacrocolpopexy using autologous fascia lata autograft. We report our experience in our first thirty-four patients.

METHODS

The operation utilizes a 4-5-cm x 15-18-cm piece of fascia lata harvested through a 3-4-inch lateral upper thigh incision. The graft is configured into a traditional Y-shaped configuration using CV-2 Goretex sutures and is used to perform sacrocolpopexy. Patients were followed by history and physical, POP-Q scores, and symptoms related to thigh harvest including visual analog pain (VAP) scores. Treatment failure was defined as symptomatic pelvic organ prolapse (POP) involving apical descent.

RESULTS

Autologous fascia lata sacrocolpopexy was performed on 34 patients with a mean age of 62. Mean follow-up was 13 months (range 2-42). Thirteen cases were open sacrocolpopexies, and 21 were robotic. Concurrent procedures included hysterectomy (9), vaginal mesh excision (7), bowel resection and rectopexy (5), and autologous sling (5). POP symptoms resolved in all 34 patients, and there were no treatment failures. The overwhelming majority of harvest site issues were minor and managed expectantly. Mean VAP score at the harvest site was 0.4 (range 0-3). Three patients developed non-bothersome thigh bulges. One patient developed a harvest site seroma. 12 patients reported mild, non-bothersome harvest site paresthesias. No thromboembolic events occurred.

CONCLUSIONS

Autologous fascia lata sacrocolpopexy is an efficacious treatment for patients who desire non-mesh POP repair. Most harvest site issues are minor and typically resolve with expectant management alone. Continued follow-up of this series is ongoing to determine long-term success of this operation.

Long-Term Outcomes and Complications of Trans-Vaginal Mesh Removal: a 14-year Experience

OBJECTIVE

To assess the long-term patient outcomes, including the resolution of symptoms and need for subsequent procedures, after vaginal mesh removals (VMR) we evaluate our 14-year experience with VMR from a tertiary center with three FPMRS-trained surgeons. Although the use of transvaginal mesh (TVM) had decreased significantly before its ban in 2019, surgeons are still treating TVM complications and performing vaginal or open/robotic VMR for mesh-related complications.

METHODS

A retrospective review of women undergoing VMR with 6 months minimum follow-up was undertaken. The data abstracted included demographics, provider notes, operative reports, pathology findings, outside medical records, peri-operative information, and reoperations.

RESULTS

From 2006 to 2020, 133 patients were identified, and 113 patients met study criteria with at least 6 months follow-up. The most common presenting symptoms were dyspareunia (77%) and pain (71%). The majority of VMR were performed vaginally (84.5%). Vaginal mesh was removed from anterior (60%), posterior (11%), and anterior and posterior (10%) compartments. Two ureteral injuries and one rectal injury were repaired intraoperatively. VMR resulted in resolution of pain in 50% of patients. Some patients had persistent pain (21%) and a few developed de novo pain (4%). More than half of the patients had dyspareunia resolution (52%), but 12% had persistent dyspareunia and 2% developed de novo dyspareunia.

CONCLUSIONS

VMR complexity requires advanced surgical expertise. Most patients undergoing VMR had resolution of their presenting symptoms. However, outcomes for pain, sexual function, continence, and/or prolapse can be unpredictable, resulting in multiple surgeries.

Efficacy and safety of anterior vaginal prolapse treatment using single incision repair system: Multicentric study

OBJECTIVE

Up to 80% of all POP surgical procedures are due to anterior vaginal wall prolapse. The aim of this study is to evaluate the efficacy and safety of transvaginal anterior mesh for POP surgical repair.

MATERIALS AND METHODS

153 consecutive patients with symptomatic or recurrent anterior vaginal prolapse undergoing surgical single-incision mesh (Calistar S) were prospectively enrolled in the study. Preoperative evaluation was performed collecting urogynecological history and performing a clinical exam, 3-day voiding diary and urodynamic testing. All incontinent patients completed the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF). Operative time, blood loss, perioperative and postoperative complications were prospectively recorded. Postoperative follow-up was scheduled at 1, 6, and 12 months with a urogynecological interview and examination. Success rate was assessed at 1, 6 and 12 months postoperatively.

RESULTS

The median follow-up was 16.4 months. None of patients had intraoperative complications. Eight patients (5%) required surgical intervention for complications (5 patients (3%) for haematoma and 3 (2%) for vaginal erosion). At 12 months of follow up 130 out of 140 patients (93%) gained the subjective cure criterion, while 129 out of 140 patients (92%) obtained the objective cure criterion. Eleven (7.8%) patients experienced stage 2 or higher prolapse recurrence and three of them with a stage ≥3 underwent reintervention. No significant differences were recorded in primary outcome at 1, 6 or 12 months postoperatively.

CONCLUSIONS

Anterior compartment prolapse repair by Calistar S (single-incision vaginal mesh) is an effective and safe procedure without significant complications.

Twenty-Five Years of the Midurethral Sling: Lessons Learned

Midurethral slings (MUS) are widely accepted for the surgical treatment of stress urinary incontinence (SUI) in cases where conservative treatment has failed. They have been shown to be a safe and effective surgical treatment for the management of SUI. However, there have recently been growing concerns regarding the safety profile of mesh procedures, generating international debate and leading to national inquiries into the effectiveness and safety of mesh implants. A multitude of clinical, technical, manufacturer-related, and other health jurisdictional factors are involved in the outcomes of MUS. Appropriate patient selection and informed consent to all treatment options, with proper guidance from healthcare providers, are critical for empowering women to choose an appropriate treatment option based on a personalized decision.

Medical Applications of Porous Biomaterials: Features of Porosity and Tissue-Specific Implications for Biocompatibility

Porosity is an important material feature commonly employed in implants and tissue scaffolds. The presence of material voids permits the infiltration of cells, mechanical compliance, and outward diffusion of pharmaceutical agents. Various studies have confirmed that porosity indeed promotes favorable tissue responses, including minimal fibrous encapsulation during the foreign body reaction (FBR). However, increased biofilm formation and calcification is also described to arise due to biomaterial porosity. Additionally, the relevance of host responses like the FBR, infection, calcification, and thrombosis are dependent on tissue location and specific tissue microenvironment. In this review, the features of porous materials and the implications of porosity in the context of medical devices is discussed. Common methods to create porous materials are also discussed, as well as the parameters that are used to tune pore features. Responses toward porous biomaterials are also reviewed, including the various stages of the FBR, hemocompatibility, biofilm formation, and calcification. Finally, these host responses are considered in tissue specific locations including the subcutis, bone, cardiovascular system, brain, eye, and female reproductive tract. The effects of porosity across the various tissues of the body is highlighted and the need to consider the tissue context when engineering biomaterials is emphasized.

Small intestinal submucosa xenograft to manage lower urinary tract prostheses perforation: a new path?

INTRODUCTION AND HYPOTHESIS

Tapes for stress urinary incontinence (SUI) and meshes for pelvic organ prolapse can result in postoperative complications, such as urethral (UP) or bladder (BP) perforations. Martius fat pad (MFP) is an historic procedure, widely used to treat lower urinary tract (LUT) fistulae. We report our experience with the insertion of the biological small intestinal submucosa (SIS) xenograft as an alternative to MFP in these prosthetic complications.

METHODS

We conducted a retrospective, monocentric study which included all patients who underwent SIS insertion during surgical removal of tape/vaginal mesh for UP or BP from 2011 to 2019. Preoperative assessment was based on history, symptoms, physical examination and urethrocystoscopy. Primary outcome was successful repair defined as absence of any LUT defect. Secondary outcomes were complications, LUT symptoms, pain and additional SUI surgical procedures.

RESULTS

Thirty-eight patients were included. Twenty-six had a UP and eight a BP. In four cases, perforation involved both the bladder neck and urethra. All LUT defects were cured. Six postoperative complications were reported (five of grade ≤ 2 and one of grade 3b according to the Clavien-Dindo classification). At the mean follow-up of 37.2 (range 6-98) months, 14 patients (36.8%) presenting a postoperative SUI underwent a SUI surgical procedure and 1 patient had a laparoscopic sacrocolpopexy for cystocele recurrence.

CONCLUSION

Absorbable SIS xenograft is an effective and safe graft for the management of lower urinary tract tape and mesh perforations. The cost has to be balanced with the good results, short operative time and no fat pad complications as in MFP.

Is transvaginal mesh procedure a potential measure for pelvic organ prolapse repair when performed by expert surgeons?

OBJECTIVES

The aim of this study was to verify the safety and efficacy of transvaginal mesh by analyzing the 2-year follow-up data of patients performed by a surgeon with a high volume of procedures.

METHODS

A total of 617 patients with pelvic organ prolapse underwent transvaginal mesh by a single surgeon. Complications and anatomical status of each patient were examined up to 24 months after surgery. Risk factors for the recurrence were also analyzed.

RESULTS

Regarding complications, we experienced 10 patients (3.8%) of bladder injuries in anterior transvaginal mesh and eight (3.4%) in anterior and posterior transvaginal mesh. Massive blood loss was observed in four patients, but there was no case of blood transfusion. Mesh exposures were seen in seven patients (1.2%). A total of 100 patients (16.2%) had prolapse recurrence, defined as the Pelvic Organ Prolapse Quantification System stage ≥II. As to recurrences on the operated compartments, we observed five patients (2.0%) for anterior transvaginal mesh, three (6.5%) for posterior transvaginal mesh, five (7.4%) for combined transvaginal mesh, and 31 (14.2%) in anterior and posterior transvaginal mesh. Regarding Point C before operation in the anterior and posterior transvaginal mesh, the recurrence rates were more than 23% in patients with a Point C of 4 or more. Binominal regression analyses showed that higher body mass index, younger age, and higher stage of uterine prolapse were significant risk factors.

CONCLUSIONS

The transvaginal mesh surgery is safe when conducted by experts. However, the recurrence rate may exceed 20% for high-stage uterine prolapse even when conducted by experts.

Host-biomaterial interactions in mesh complications after pelvic floor reconstructive surgery

Polypropylene (PPL) mesh is widely used in pelvic floor reconstructive surgery for prolapse and stress urinary incontinence. However, some women, particularly those treated using transvaginal PPL mesh placement for prolapse, experience intractable pain and mesh exposure or extrusion. Explanted tissue from patients with complications following transvaginal implantation of mesh is typified by a dense fibrous capsule with an immune cell-rich infiltrate, suggesting that the host immune response has a role in transvaginal PPL mesh complications through the separate contributions of the host (patient), the biological niche within which the material is implanted and biomaterial properties of the mesh. This immune response might be strongly influenced by both the baseline inflammatory status of the patient, surgical technique and experience, and the unique hormonal, immune and microbial tissue niche of the vagina. Mesh porosity, surface area and stiffness also might have an effect on the immune and tissue response to transvaginal mesh placement. Thus, a regulatory pathway is needed for mesh development that recognizes the roles of host and biological factors in driving the immune response to mesh, as well as mandatory mesh registries and the longitudinal surveillance of patients.

Mesh exposure after transvaginal mesh prolapse surgery: Out of permissible range?

OBJECTIVES

To investigate the prevalence of postoperative complications after transvaginal mesh prolapse surgery, and whether modified transvaginal mesh prolapse surgery (without transobturator arms or posterior mesh) has less prevalence of mesh exposure compared with conventional transvaginal mesh prolapse surgery.

METHODS

Medical charts were retrospectively examined for 2648 patients who underwent transvaginal mesh prolapse surgery in a general hospital (2006-2017). Conventional transvaginal mesh prolapse surgery (Prolift-type, n = 2258) was used, with a shift from 2015 to modified transvaginal mesh prolapse surgery (Uphold-type, n = 330). Patients were instructed to have >2 years of follow up and to report if they had problems regarding the operation.

RESULTS

The prevalence of mesh exposure was 34 out of 2648 (1.28%); 18 vagina (0.68%), 10 bladder (0.38%), two ureter (0.08%) and four rectum (0.15%). The modified transvaginal mesh prolapse surgery group had only one case with vaginal exposure. Vaginal exposure was managed transvaginally or followed by observation. Rectal exposure was managed transvaginally without colostomy. Bladder exposure was managed by transurethral resection with saline. Open ureterocystostomy was carried out to treat ureteral exposure. In the conventional transvaginal mesh prolapse surgery group, three cases of ureteral stenosis and one case with vaginal evisceration of the small intestine were managed transvaginally. The prevalence of postoperative chronic pain was 13 out of 2648 (0.49%; with one patient in the modified transvaginal mesh prolapse surgery group). The patients underwent pharmacotherapy, and one patient underwent additional surgical treatment.

CONCLUSIONS

The reoperation rate as a result of complications after transvaginal mesh prolapse surgery seems to be low. The reoperation rate as a result of prolapse recurrence is also low. A shift from conventional transvaginal mesh prolapse surgery to modified transvaginal mesh prolapse surgery might contribute to a further decrease in the risk of complications.

Techniques of transvaginal mesh prolapse surgery in Japan, and the comparison of complication rates by surgeons' specialty and experience

OBJECTIVES

To investigate techniques of transvaginal mesh prolapse surgery in Japan, and compare complication rates by surgeons' specialty and experience with transvaginal mesh prolapse surgery.

METHODS

We carried out an anonymous questionnaire survey for surgeons attending a national transvaginal mesh prolapse surgery meeting in 2010. The surgeons were asked to state their specialty, practice patterns, transvaginal mesh prolapse surgery techniques and the number of transvaginal mesh prolapse procedures carried out as an operator including the complications that occurred.

RESULTS

A total of 118 surgeons (59% of the attendees) responded to the questionnaire. The mean age was 44.0 ± 9.1 years, 54 (46%) were gynecologists and 64 (54%) were urologists. All urologists and 78% of gynecologists carried out anti-incontinence surgery (midurethral sling), whereas more gynecologists (93%) carried out native tissue repair than urologists (73%). Most of both specialties (each 98%) avoided prophylactic anti-incontinence surgery during prolapse surgery. Concomitant hysterectomy during transvaginal mesh prolapse surgery was generally avoided. Surgeons reached a consensus regarding the critical transvaginal mesh prolapse surgery techniques: hydrodissection (98%) and the full-thickness dissection (the "Lychee layer"; 69%). A total of 11 935 Prolift-type transvaginal mesh prolapse procedures were carried out and the following complications were reported: bladder injury (1.6%), rectal injury (0.3%), ureteral injury (0.1%), blood transfusion (0.2%), vaginal exposure (2.8%) and recurrence requiring reoperation (1.1%). Although complications did not differ between specialty, bladder injury, transfusion and vaginal exposure were less prevalent with experienced surgeons (≥50 transvaginal mesh prolapse surgery cases).

CONCLUSIONS

Over 10 000 transvaginal mesh prolapse surgery had been carried out in Japan with a relatively low complication rate until 2010. This survey shows that surgeons' experience could lead to a decrease in the amount of transvaginal mesh prolapse surgery complications.

Management of Vaginal Mesh Exposures Following Female Pelvic Reconstructive Surgery

PURPOSE OF REVIEW

To discuss considerations and current evidence for the diagnosis and management of vaginal mesh exposures following female mesh-augmented anti-incontinence and pelvic organ prolapse surgery.

RECENT FINDINGS

Since the introduction of mesh into female pelvic surgery, various applications have been reported, each with their own unique risk profile. The most commonly encountered mesh-related complication is vaginal mesh exposure. Current evidence on the management of vaginal mesh exposure is largely limited to observational studies and case series, though this is continuing to expand. We present a synthesis of the available data, as well as clinical and surgical approaches to managing this complication. It is important for surgeons to be familiar with the management of vaginal mesh exposures. Depending on the patient's presentation and goals, there is a role for conservative measures, mesh revision, or mesh excision. Further study is warranted to standardize mesh resection techniques and explore non-surgical treatments.

Pain Resolution and Recurrent Prolapse Rates Following Vaginal Mesh Removal

OBJECTIVE

To evaluate pain resolution and recurrent prolapse following removal of painful pelvic organ prolapse (POP) mesh.

METHODS

This was an IRB-approved retrospective review of patients who underwent POP mesh removal from 2009 to 2018 for the primary indication of pain and/or dyspareunia. Factors of interest included mesh type, complete versus partial removal, presenting symptom(s), and recurrent prolapse. Complete removal was defined as complete excision of all possible mesh, including arms, and partial removal was anything less. Postoperative symptom improvement was categorized as resolved, improved, or unresolved.

RESULTS

Ninety-two mesh removal patients were identified, 78 of whom underwent mesh removal for pain or dyspareunia, with mean follow-up of 17.25 months (range: 0.46-60.25). Overall, presenting symptoms resolved or improved in 85.9%. In the 45 complete removal patients, 46.7% resolved, 40.0% improved, and 11.1% unresolved compared to 51.5% resolved, 33.3% improved, and 12.1% unresolved in the 33 partial removal patients (P = .82). Recurrent symptomatic POP developed in 31.1% of patients after complete removal compared to 15.2% after partial removal (P = .12). Overall, 23 (30.3%) patients required additional reconstructive procedures.

CONCLUSION

Most patients experienced resolution or improvement in painful symptoms after any degree of mesh removal. Complete removal was not significantly associated with greater symptom improvement compared to partial removal. Complete removal was associated with a higher percentage of recurrent POP, but this association was not statistically significant. Less than one-third of patients required additional surgery.

[Pelvic and perineal pain after genital prolapse: A literature review]

INTRODUCTION

Pelvic and perineal pain after genital prolapse surgery is a serious and frequent post-operative complication which diagnosis and therapeutic management can be complex.

MATERIALS ET METHODS

A literature review was carried out on the Pubmed database using the following words and MeSH : genital prolapse, pain, dyspareunia, genital prolapse and pain, genital prolapse and dyspareunia, genital prolapse and surgery, pain and surgery.

RESULTS

Among the 133 articles found, 74 were selected. Post-operative chronic pelvic pain persisting more than 3 months after surgery according to the International Association for the Study of Pain. It can be nociceptive, neuropathic or dysfunctional. Its diagnosis is mainly clinical. Its incidence is estimated between 1% and 50% and the risk factors are young age, the presence of comorbidities, history of prolapse surgery, severe prolapse, preoperative pain, invasive surgical approach, simultaneous placement of several meshes, less operator experience, increased operative time and early post-operative pain. The vaginal approach can cause a change in compliance and vaginal length as well as injury to the pudendal, sciatic and obturator nerves and in some cases lead to myofascial pelvic pain syndrome, whereas the laparoscopic approach can lead to parietal nerve damage. Therapeutic management is multidisciplinary and complex.

CONCLUSION

Pelvic pain after genital prolapse surgery is still obscure to this day.

Fertility-Sparing Surgery Using Knitted TiNi Mesh Implants and Sentinel Lymph Nodes: A 10-Year Experience

Objectives: The aim of this cohort study is to improve the procedure of fertility-sparing surgery and to assess oncological and reproductive follow-up outcomes after radical trachelectomy (RT) for cervical cancer (T_1a2-1bN_xM₀).Methods: We have suggested the method combining sentinel lymph nodes (SLNs) and cervicoisthmic cerclage using a superelastic knitted TiNi mesh (KTNM) implant to facilitate the primary biomechanical/retention function of the uterus. Sixty-eight consented patients, who underwent fertility-sparing surgery using both transabdominal and laparoscopic route from 2009 through 2019, were recruited in the study and prospectively followed for a mean of 69 months.Results: There were no intraoperative or postoperative complications. No cervical stenoses or mesh failures were noted in all cases. The 5-year overall and recurrence-free survival rates were 100% and 97%, respectively. Two patients indicated recurrence, it occurred in 3 and 36 months. There were 19 (28%) spontaneous pregnancies, 6 resulted in full-term delivery, whereas 2 and 11 ended in miscarriage and early abortion, respectively.Conclusions: This sparing-surgery technique is turned out to be feasible and efficient as allows to achieve well oncologic and fertility outcomes, mimicking the effect of the cervix. It complements existing surgical approaches and may provide further insight into how to overcome challenges even in aggravated cases or previously failed procedures.

Do we have adequate data to construct a valid algorithm for management of synthetic midurethral sling complications? ICI-RS 2019

BACKGROUND

Synthetic midurethral sling (MUS) procedures, purported for the last two decades as the gold standard surgical treatment for stress urinary incontinence, have been in creasingly scrutinized in recent years with regard to the rate and severity of complications.

METHODS

During the International Consultation on Incontinence Research Society meeting held in Bristol, UK, in 2019, a multidisciplinary panel held a think tank and discussed the contemporary evidence pertaining to the classification, investigation, and treatment of MUS complications.

RESULTS

The current classification system of mesh-related complications was discussed, and shortcomings were identified. The lack of a standardized clinical pathway was noted, and the value of clinical investigations and surgical treatments was difficult to fully evaluate. The paucity of high-level evidence was a common factor in all discussions, and the difficulties with setting up relevant randomized-controlled trials were highlighted.

CONCLUSIONS

The outcome of the think-tank discussions is summarized with a set of recommendations designed to stimulate future research.

Mesh complications: best practice in diagnosis and treatment

Mesh was a promising, minimally invasive, and 'gold standard' treatment for urinary stress incontinence. Time has shown that complications from these devices can happen early, or even several years, after mesh placement and can be catastrophic. Pain, erosion, voiding dysfunction, infection, recurrent UTIs [urinary tract infections (UTIs)], fistulae, organ perforation, bleeding, vaginal scarring, neuromuscular alterations, LUTS (lower urinary tract symptoms), bowel complications and even immune disorders have been linked to mesh. Various tools, such as imaging, endoscopic and functional studies, are available for diagnosis of mesh complications. Since the spectrum of complications is wide, involvement of other specialties is usually beneficial in the diagnosis and management of these complications. There is still much to learn on the accuracy and utility of diagnostic studies in each type of complication. Evidence on the best diagnostic and treatment pathways for these complications is scarce but continuously growing as information is being reported, and we continue to gain expertise in dealing with patients affected by mesh. Treatment options include conservative and medical management initially and then open or minimally invasive surgical procedure approaches. This article will describe diagnostic and treatment pathways for mesh complications.

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

There are a variety of surgical management strategies to help surgeons repair pelvic organ prolapse (POP). Surgical treatment for POP includes native tissue repair, augmentation with mesh, and minimally invasive surgeries. Currently, laparoscopic or robotic techniques for POP repair are increasing in popularity and continuing to evolve. The aim of this review is to present an up-to-date review of surgical techniques used for POP repair and to discuss ways to optimize surgical outcomes.

Comparison of the efficiency of partial versus subtotal mesh removal on urogenital distress and sexual functions after stress urinary incontinence surgery

OBJECTIVE

To compare the efficiency of the partial mesh removal (PMR) versus subtotal mesh removal (SMR) on urogenital distress and sexual functions in patients who experienced vaginal mesh extrusion.

MATERIAL AND METHODS

Between June 2014 and January 2018, 45 patients who experienced vaginal mesh extrusion following midurethral sling surgeries and therefore underwent mesh excision were evaluated retrospectively. The effectiveness of PMR and SMR was compared using the "Urinary Distress Inventory-6 (UDI-6)" and "Female Sexual Function Index (FSFI)" forms, at the 6th month postoperatively.

RESULTS

Fourteen PMR-patients and 21 SMR-patients who met the study criteria were evaluated for the study. There was a significant improvement in UDI-6 scores and FSFI scores in both PMR and SMR groups at the 6^th month postoperatively (p=0.001, p=0.001, p=0.001, and p=0.001, respectively). When the two groups were compared in terms of improvement rates, there was no significant difference in UDI-6 scores [(-)30.21±6.56% vs. (-)26.33±9.01%, p=0.222]. However, there was a statistically significant improvement in the FSFI scores in the SMR group [(+)83.71±14.81% vs. (+)124.42±36.82%, p=0.001]. There was no significant difference in overactive bladder symptoms between the two groups, with a decrease of 75% in the PMR group and 71.42% in the SMR group (p=0.721). Recurrent stress urinary incontinence was observed in two (14.2%) patients in the PMR group and four (19.1%) patients in the SMR group at the 6th month postoperatively (p=0.544).

CONCLUSION

In cases where extrusion is developed, subtotal/total mesh removal provides a significant improvement in patients' complaints of sexual dysfunction related to extrusion.

Management of vaginal mesh exposure: A systematic review

Objectives: To identify various predisposing factors, the clinical presentation, and the management of vaginal mesh-related complications, with special emphasis on mesh exposure and the indications for and results of vaginal mesh removal.

Methods: A systematic literature review was performed using a search strategy based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria. PubMed was queried for studies regarding aetiology, risk factors, and management of vaginal mesh exposure from 1 January 2008 to June 2018. Full-text articles were obtained for eligible abstracts. Relevant articles were included, and the cited references were used to identify relevant articles not previously included.

Results: A total of 102 abstracts were identified from the PubMed search criteria. An additional 45 studies were identified based on review of the cited references. After applying eligibility criteria and excluding impertinent articles, 58 studies were included in the final analysis.

Conclusion: Numerous studies have found at least some degree of symptomatic improvement regardless of the amount of mesh removed. Focal areas of exposure or pain can be successfully managed with partial mesh removal with low rates of complications. With partial mesh removal, many patients will ultimately require subsequent mesh removal procedures. For this reason, complete mesh excision is an alternative for patients with diffuse vaginal pain, large mesh exposure, and extrusion of mesh into adjacent viscera. However, when considering complete mesh removal, it is important to counsel patients regarding possible complications of removal and the increased risk of recurrent stress urinary incontinence and pelvic organ prolapse postoperatively.

The autologous rectus fascia sheath sacrocolpopexy and sacrohysteropexy, a mesh free alternative in patients with recurrent uterine and vault prolapse: A contemporary series and literature review

Introduction:

About 40% of women suffer pelvic organ prolapse (POP) in a lifetime. The current standard intervention for vault prolapse is a mesh sacrocolpopexy or sacrohysteropexy. However, patients and surgeons are increasingly hesitant to use mesh given recent the UK and Food and Drug Administration warnings and litigation. A possible alternative is to use autologous tissue to support the vault, as a mesh-free solution. We report the outcomes from an initial series of autologous rectus fascia sheath (RFS) sacrocolpopexy and sacrohysteropexy in patients with complex pelvic floor dysfunction.

Patients and Methods:

All patients had previous, multiple urological/gynecological surgery and declined standard mesh repairs. All had preoperative videourodynamics and defecating magnetic resonance imaging evaluation. The autologous POP repair was performed using 10–18 cm of rectus sheath with a similar technique to that employing mesh to support the anterior-posterior vaginal walls or encircle the cervix and secured to the sacral promontory.

Results:

Seven patients with a mean age of 52 (33–64) years underwent autologous RFS POP repair between 2014 and 2017. Mean follow-up is 16 (range 2–33) months. All patients have durable result at last follow-up. No significant complications are reported.

Conclusions:

This is the first report of patients with complex pelvic floor dysfunction and apical POP being managed with autologous RFS sacrocolpopexy/sacrohysteropexy, and only the second report of a free graft being utilized with success. Autologous RFS sacrocolpopexy/sacrohysteropexy avoids the 10%–15% risks of mesh-related complications. Further studies of long-term durability are needed.

Management of complications arising from the use of mesh for stress urinary incontinence-International Urogynecology Association Research and Development Committee opinion

INTRODUCTION AND HYPOTHESIS

Management of pain or mesh exposure complications after stress incontinence surgery has become a new issue over the last 20 years with the introduction of mesh techniques to treat stress incontinence. There is much debate regarding the incidence of complications and how best to treat them.

METHODS

A working subcommittee from the International Urogynecology Association (IUGA) Research and Development (R&D) Committee was formed. An initial document was drafted based on a literature review. The review focused on complications of vaginal mesh inserted for stress incontinence. After evaluation by the entire IUGA R&D Committee revisions were made. The final document represents the IUGA R&D Committee Opinion.

RESULTS

The R&D Committee Opinion reviews the literature on the management of complications arising from the use of mesh for stress urinary incontinence. The review concentrated on the assessment and treatment of pain and exposure.

CONCLUSIONS

Complications after surgery for stress incontinence using mesh may not be common occurrences for individual surgeons. Complications may be difficult to manage and outcomes are variable. Specialist centres and a multidisciplinary approach may optimise treatment and reporting of outcomes.

Questions surrounding the optimal time for surgical treatment of pelvic organ prolapse

OBJECTIVE

The purpose of study is to evaluate the recurrence rate of pelvic organ prolapse after surgical treatment and pre- to postoperative changes in sexual function of patients with different stages of pelvic organ prolapse.

METHODS

The presented study was a single-centre observational nonrandomized analysis of an ongoing prospective cohort study evaluating anatomical and clinical outcomes in reproductive aged women scheduled for nature tissue repair of POP staged I-III. Two hundred and ten women were recruited, of whom 120 (57.1%) had the advanced prolapse form (POP-Q III). Women at preoperative POP stage I-II were compared with women at stage III without apical prolapse.

RESULTS

The best effectively rate with low recurrence depends on preoperative prolapse stage. The overall objective success rate was about 80% in five years in patients with preoperative stage I-II. Study shows a significant improvement in sexual function in all patients with pelvic organ prolapse in five years after surgery.

CONCLUSION

This study showed that women with advanced POP have a higher risk of recurrence after POP native tissue repair compared with early stages and proved the improvement of sexual function especially in women with advanced prolapse forms. Women with early stage of POP should be advised to postpone surgery until progression of complaints because of the high recurrence risk.

Female stress urinary incontinence MDT

The management of female stress urinary incontinence (SUI) has come under scrutiny in recent years following growing reports of mesh-related complications. Patients require thorough evaluation and management as part of a multidisciplinary team, and extensive counselling about the surgical treatment options is imperative. There is no clear consensus on the optimal management of the complex group of patients with mesh-related complications or recurrent SUI. We present two cases of female SUI to highlight the key factors to be considered when managing these patients.

Level of evidence: Level 5.

Long-term experience of vaginal vault prolapse prevention at hysterectomy time by modified McCall culdoplasty or Shull suspension: Clinical, sexual and quality of life assessment after surgical intervention

OBJECTIVES

The aim of this study was to evaluate the effectiveness of modified McCall culdoplasty or Shull suspension in preventing vaginal vault prolapse after vaginal hysterectomy and the long-term impact on quality of life and sexual function.

STUDY DESIGN

Retrospective analysis in 414 patients underwent vaginal hysterectomy for pelvic organ prolapse (POP) and vaginal suspension through modified McCall culdoplasty (group A) or Shull suspension (group B) was evaluated. Clinical features and concomitant surgical procedures were assessed. Surgical data and perioperative and postoperative complications have also been analyzed. Clinical characteristics, urinary symptoms, POP-Q score classification, Quality of Life and Sexual Function were evaluated at baseline and at median follow up with P-QoL, ICIQ-UI-SF, PISQ-12, FSFI, FSDS questionnaires.

RESULTS

The median follow up was 8.9 year (5.1-14.2 years). 200 women in group A and 214 in group B were evaluated. Vaginal vault prolapse occurred in 2 patients in group A and in 2 patients in group B. POP-Q score for all compartments showed a significant (p < 0.001) decrease for both groups without significant differences between the 2 groups. The total vaginal length (TVL) was reduced in greater proportion in McCall group (p < 0.001). P-QoL and ICIQ-UI-SF questionnaires documented an improvement for both groups (p < 0.001). The number of patients who regularly practice sexual activity increased in both groups, but patients in group B experienced a better quality of sexual life evaluated with PISQ-12 and FSFI.

CONCLUSIONS

Both surgical techniques showed effectiveness and safety in preventing vaginal vault prolapse in women who underwent vaginal hysterectomy, with a significant improvement in quality of life and sexuality. Shull technique demonstrated greater improvement in sexual function.
