Abstract
OBJECTIVES To detail the history of synthetic mid-urethral slings (SMUSs) and fascial slings, their efficacy, associated complications, and changes to practice that have occurred after the issuing of the 2011 US Food and Drug Administration (FDA) Safety Communication statement on transvaginal mesh (TVM), and to highlight the need for surgical registries and high-quality randomised controlled data to guide recommendations for continence procedures, in view of current concerns regarding mesh. METHODS A literature search was conducted in EMBASE, PubMed, and the Cochrane Database of systematic reviews to identify articles published from 2011 onward, following the FDA Safety Communication regarding TVM. RESULTS Prior to the formal FDA Safety Communication in 2011, TVM was considered a safe option for the treatment of both pelvic organ prolapse (POP) and stress urinary incontinence (SUI). The 2011 FDA safety communications and ensuing widely publicised litigation against TVM manufacturers have shifted both surgeon and patient acceptance of mesh products. Several efforts by medical and government bodies have been made to establish ways to monitor the surgical outcomes and safety of mesh products. The Australasian Pelvic Floor Procedure Registry is one such example. Although SMUSs have a long and established safety profile, perceptions of mesh products for SUI have also been negatively affected. The extent of this, however, has yet to be adequately measured through qualitative and quantitative data. The available data suggest it has been difficult for patients and consumers to distinguish between TVM morbidity for POP vs SUI. Furthermore, there remains a lack of high-quality randomised or real-world registry data to definitively exclude the SMUS from the SUI treatment algorithm. Since SMUSs are a viable option for SUI treatment, the concept of a 'post-mesh world' remains contentious. CONCLUSION Controversies surrounding SMUSs have changed the treatment landscape of SUI. Against the background of significant litigious action following the FDA warnings against mesh use, there has been significant reduction in the uptake of synthetic mesh products. Although there are ample data related to surgical outcomes and safety for both autologous fascial and retropubic SMUSs in carefully selected patients, informed consent and surgical training will be of paramount importance as newer synthetic materials reach clinical maturity.

Introducing a New Technique for Fascial Closure to Avoid Renal Allograft Compartment Syndrome in Pediatric Recipients: The Use of Tutoplast® Fascia Lata. Front Surg 2022; 9:840055. [PMID: 35599790 PMCID: PMC9120621 DOI: 10.3389/fsurg.2022.840055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Accepted: 03/21/2022] [Indexed: 11/17/2022] Open
Abstract
Introduction Renal allograft compartment syndrome (RACS) is a complication that infrequently occurs after renal transplantation. Tight muscle closure may lead to RACS due to compression of renal parenchyma or kinking of the renal vessels. Many techniques have been proposed in an attempt to achieve tension-free closure, which can be specially challenging in child recipients. We present our experience with Tutoplast® Fascia Lata (RTI Surgical Tutogen Medical GmbH Industriestrasse 6, 91077 Neunkirchen am Brand, Germany) closure. Methods All pediatric patients who underwent renal transplantation in our center between 2012 and 2021 were reviewed. Eight patients with Tutoplast® Fascia Lata placed at the time of initial transplantation were identified. Donor and recipient characteristics, Doppler ultrasound findings, and overall patient and graft survival rates were analyzed. Results Doppler ultrasound was performed intra-operatively after abdominal wall closure. If any sign of vascular compromise was seen, the abdominal wall was opened and the graft was revised. The Tutoplast® Fascia Lata implant was used to perform tension-free fascia closure and, afterwards, a Doppler ultrasound was performed to confirm the optimal renal artery perfusion and venous patency. Three of the renal transplantations were from a cadaver donor, with two of them en bloc. Living donor transplantation was performed in four cases. Among which, there was a case of auto-transplantation due to bilateral renal artery stenosis. None of the patients presented any complications of either short or long term that was derived from the abdominal closure with Tutoplast® Fascia Lata. There was also no record of graft failure till datum. Conclusions Restricted volume of the recipient pelvic cavity and the size discrepancy between the recipient pelvic cavity space and the donor adult kidney may lead to RACS. Other situations that occur more infrequently, i.e., as en bloc or auto-transplantation, are prone to suffer the same problem. Tutoplast® Fascia Lata is a safe option for these patients.

Abstract
OBJECTIVES The objective of this study was to compare perioperative outcomes of autologous bladder neck fascial slings (ABNFS) between rectus fascia and fascia lata harvest sites. METHODS We analyzed women undergoing ABNFS in the 2006 to 2015 American College of Surgeons National Surgical Quality Improvement Program database, separating rectus fascia and fascia lata harvest sites by Current Procedural Terminology codes. We compared the 2 harvest sites for perioperative outcomes within 30 days including adverse events, readmission, and reoperation as well as operative time and length of hospital stay. The primary outcome was a composite of postoperative adverse events, readmission, and reoperation. A multivariable logistic regression model was used incorporating race, smoking status, surgical specialty, anesthesia class, concurrent procedures, body mass index, operating time, and length of hospital stay. RESULTS A total of 161 women in the database underwent ABNFS: 126 (78.3%) rectus fascia and 35 (21.7%) fascia lata harvest. Patients undergoing rectus fascial harvest were more likely to be white (140 [90.5%] rectus vs 26 [74.3%] fascia lata, P=0.02) and more likely to have ABNFS by a urologist (117 [93%] rectus vs 23 [66%] fascia lata, P < 0.01). There were no significant differences in operative time, length of stay, rate of reoperation, nonserious or serious adverse events, or readmission between the 2 harvest site groups. The 2 harvest sites had similar composite morbidity (adjusted odds ratio of 0.88 for rectus fascia; 95% confidence interval, 0.21-3.75; P=0.87). CONCLUSIONS Rectus fascia and fascia lata harvest for ABNFS have similar perioperative outcomes.

Abstract
This article describes the operative technique of autologous fascial pubovaginal sling (AFPVS) surgery, examines the senior author's outcomes with AFPVS, compares these outcomes with those of other large studies and meta-analyses, and compares the safety and efficacy of AFPVS with those of the synthetic midurethral sling (SMUS). Recently, the SMUS has become the treatment of choice for most surgeons. The efficacy of the SMUS remains unchallenged and comparable with that of AFPVS, but SMUS are associated with more severe complications. In the author's opinion, the AFPVS should remain the gold standard for treating SUI.

Abstract
INTRODUCTION In this review, we discuss major advancements and common challenges in constructing and regenerating a neo-urinary conduit (NUC). First, we focus on the need for regenerating the urothelium, the hallmark the urine barrier, unique to urinary tissues. Second, we focus on clinically feasible scaffolds based on decellularized matrices and molded collagen that are currently of great research interest. AIM To discuss the major advancements in constructing a tissue-engineered NUC (TE-NUC) and the challenges involved in their successful clinical translation. METHODS A comprehensive search of peer-reviewed literature from PubMed and Google Scholar on subjects related to urothelium regeneration, decellularized tissue matrices, and collagen scaffolds was conducted. MAIN OUTCOME MEASURE We evaluated the main biological and mechanical functions of urinary tissues, the need for TE implants to create a urinary diversion, the reasons for their failures in clinical settings, and the applications of decellularized tissue matrices and collagen-based molded scaffolds in their regeneration. RESULTS It is necessary to create a urine barrier that prevents urine leakage into the stroma that can cause failure of the graft. Despite the regeneration potential of the urothelium, the limited supply of healthy urothelial cells in patients with bladder cancer remains a major challenge. In this context, alternative strategies, such as transdifferentiation of cells into urothelium or engineered scaffolds based on decellularized tissues and molded collagen with robust urine barrier properties, are active areas of research. CONCLUSION There is an immediate need for developing a functional TE-NUC that can improve the quality of life of patients with bladder cancer. It is possible to achieve a TE-NUC by bioengineering an implant that has appropriate biological and mechanical properties to store and transport urine. We anticipate that future advancements in urothelium regeneration and material design will lead us closer to successful neo-urinary tissue constructs. Singh A, Bivalacqua TJ, Sopko N.

Abstract
BACKGROUND Polypropylene mesh used as a mid-urethral sling is associated with severe clinical complications in a significant minority of patients. Current in vitro mechanical testing shows that polypropylene responds inadequately to mechanical distension and is also poor at supporting cell proliferation. AIMS AND OBJECTIVES Our objective therefore is to produce materials with more appropriate mechanical properties for use as a sling material but which can also support cell integration. METHODS Scaffolds of two polyurethanes (PU), poly-L-lactic acid (PLA) and co-polymers of the two were produced by electrospinning. Mechanical properties of materials were assessed and compared to polypropylene. The interaction of adipose derived stem cells (ADSC) with the scaffolds was also assessed. Uniaxial tensiometry of scaffolds was performed before and after seven days of cyclical distension. Cell penetration (using DAPI and a fluorescent red cell tracker dye), viability (AlamarBlue assay) and total collagen production (Sirius red assay) were measured for ADSC cultured on scaffolds. RESULTS Polypropylene was stronger than polyurethanes and PLA. However, polypropylene mesh deformed plastically after 7 days of sustained cyclical distention, while polyurethanes maintained their elasticity. Scaffolds of PU containing PLA were weaker and stiffer than PU or polypropylene but were significantly better than PU scaffolds alone at supporting ADSC. CONCLUSIONS Therefore, prolonged mechanical distension in vitro causes polypropylene to fail. Materials with more appropriate mechanical properties for use as sling materials can be produced using PU. Combining PLA with PU greatly improves interaction of cells with this material.

Abstract
Stress urinary incontinence (SUI) and pelvic organ prolapse (POP) are major health issues that detrimentally impact the quality of life of millions of women worldwide. Surgical repair is an effective and durable treatment for both conditions. Over the past two decades there has been a trend to enforce or reinforce repairs with synthetic and biological materials. The determinants of surgical outcome are many, encompassing the physical and mechanical properties of the material used, and individual immune responses, as well surgical and constitutional factors. Of the current biomaterials in use none represents an ideal. Biomaterials that induce limited inflammatory response followed by constructive remodelling appear to have more long term success than biomaterials that induce chronic inflammation, fibrosis and encapsulation. In this review we draw upon published animal and human studies to characterize the changes biomaterials undergo after implantation and the typical host responses, placing these in the context of clinical outcomes.

Abstract
Stress urinary incontinence (SUI) is the most common type of urinary incontinence, and approximately 200 different methods have been described for its surgical management. A better understanding of the pathophysiology of SUI has led to the development of surgical therapies focused on creating a strong suburethral supportive layer and urethral resistance. The most important advantage of the pubovaginal sling (PVS) procedure is that it restores urethral resistance during stress maneuvers to prevent incontinence, while improving urethral coaptation at rest and allowing for spontaneous micturition. Various autologous, allograft, xenograft and synthetic materials have been used for the PVS. The autologous PVS procedure for the treatment of SUI offers the highest success rate and is the most commonly used PVS surgical method. Unlike xenograft and allograft materials, the autologous procedure does not result in a tissue reaction and is associated with a low rate of material-related complications.

Abstract
PURPOSE We describe and evaluate a transobturator approach to urethral sling placement using autologous rectus fascia for the management of female stress urinary incontinence. MATERIALS AND METHODS We performed a feasibility study of 10 cases of autologous transobturator mid urethral sling placement for stress urinary incontinence. The procedure includes an anterior vaginal dissection performed in the standard fashion for a mid urethral sling and harvest of a strip of rectus fascia. A trocar is passed through each obturator foramen and the fascial stay sutures are retracted through the skin incisions. The sling is appropriately tensioned and the stay sutures are tied. Patient outcomes were measured by a 24-hour pad weight test and ICIQ-FLUTS score. RESULTS Median patient age was 57 years (IQR 48, 69.5) and median body mass index was 30.3 kg/m(2) (IQR 25.2, 32.4). Median followup was 4 months (range 3 to 5). All patients demonstrated a reduction in leakage with 80% being completely dry (0 gm on 24-hour pad test and not wearing pads). Overall there was significant improvement in postoperative vs preoperative 24-hour pad weight (p=0.02). Likewise, all subscores of the ICIQ-FLUTS were significantly improved after surgery, including frequency (p=0.006), voiding (p=0.04) and incontinence (p=0.002). Of the 9 eligible cases 6 (67%) were performed on an outpatient basis. One patient performed intermittent self-catheterization for 24 hours after sling placement. No patients experienced severe (Clavien III-V) postoperative complications or required urethrolysis. CONCLUSIONS Autologous transobturator urethral sling placement appears to be technically feasible with excellent short-term outcomes. Longer followup and larger series are needed for validation.

Abstract
INTRODUCTION AND HYPOTHESIS Cell-based tissue engineering strategies could potentially provide attractive alternatives to surgical reconstruction of native tissue or the use of surgical implants in treating pelvic organ prolapse (POP). METHODS Based on a search in PubMed, this review focuses on candidate cell types, scaffolds, and trophic factors used in studies examining cell-based tissue engineering strategies to treat POP, stress urinary incontinence (SUI), and the closely related field of hernias. RESULTS In contrast to the field of SUI, the use of cell-based tissue engineering strategies to treat POP are very sparsely explored, and only preclinical studies exist. CONCLUSION The available evidence suggests that the use of autologous muscle-derived cells, fibroblasts, or mesenchymal stem cells seeded on biocompatible, degradable, and potentially growth-promoting scaffolds could be an alternative to surgical reconstruction of native tissue or the use of conventional implants in treating POP. However, the vagina is a complex organ with great demands of functionality, and the perfect match of scaffold, cell, and trophic factor has yet to be found and tested in preclinical studies. Important issues such as safety and economy must also be addressed before this approach is ready for clinical studies.

Abstract
PURPOSE Evaluate the impact autologous fascial sling (AFS) and tension-free vaginal tape (TVT) procedures on quality-of-life in incontinent women. MATERIALS AND METHODS Forty-one women were randomly distributed into two groups. Group G1 (n = 21), underwent AFS and group G2 (n = 20) TVT implant. The clinical follow up was performed at 1, 6, 12 and 36 months. RESULTS TVT operative time was significantly shorter than AFS. Cure rates were 71% at 1 month, 57% at 6 and 12 months in G1. In G2, cure rates were 75% at 1 month, 70% at 6 months and 65% at 12 months; there was no significant difference between groups. As regards the satisfaction rate, there was no statistical difference between groups. Analysis of quality of life at 36 months revealed that there was no significant difference between groups. CONCLUSION Similar results between AFS and TVT, except for operative time were shorter in TVT.

Abstract
This randomised control trial compares full-length autologous slings (Group A: 81 women) with a modified "sling-on-a-string" (Group B: 84 women) technique for the treatment of stress urinary incontinence (SUI). Primary outcomes are quality of life (QoL) scores; Group A/Group B. The IIQ-7 scores decrease from 1.91/1.85 at baseline to 0.65/0.72 at 12 months and 0.85/0.92 at +5 years. The UDI-6 scores decrease from 1.85/1.61 at baseline to 0.66/0.62 at 12 months and 1.22/1.08 at +5 years. The incidence of SUI is 13% at 3 months but averages 53% at +5 years. Both techniques offer similar improvements. The shorter sling is quicker, less painful and with less hospital readmissions. The 'sling-on-a-string' technique is as effective as the standard technique with better short-term sequelae. The incidence of SUI post-autologous slings rises over the long term.

Abstract
PURPOSE OF REVIEW The purpose of this paper is to review the literature published during 2005 on nonautologous biological slings for the treatment of stress urinary incontinence. RECENT FINDINGS Little has been done by the way of research to assess adequately whether nonautologous biological slings perform better or worse than other types of slings. Three cohort studies and two comparative studies have been reported, but no randomized controlled trials have been published during the last year comparing biological slings with synthetic slings. Sporadic reports of unexpectedly high recurrent stress incontinence rates with some biological slings have come into light. SUMMARY Nonautologous biological slings are safe and simple to implant. Long-term outcomes, however, remain uncertain. A risk of complete failure is possible.

Abstract
OBJECTIVE To assess the outcome of using modified human fascia lata (Tutoplast, Mentor Corp, Santa Barbara, CA, USA) in the surgical management of Peyronie's disease (PD), as the penile deformity associated with PD can be corrected by plaque incision and saphenous vein grafting (Lue procedure). PATIENTS AND METHODS In all, 14 patients (mean age 51 years, range 34-59) with PD had their penile deformity corrected by plaque incision and Tutoplast grafting. Three patients had a previous unsuccessful Nesbit operation. The mean (range) penile deformity before surgery was 67.2 (20-90) degrees and the mean follow-up was 31 (17-37) months. RESULTS Using set criteria, 13 patients were satisfied (excellent or satisfactory) with the results of surgery. The penis was completely straight in 11 of 14 patients. One patient developed de novo erectile dysfunction after surgery. In 10 patients there was no penile shortening, whereas four reported penile shortening of >1 cm. CONCLUSION Fascia lata Tutoplast grafts provide a reliable and well tolerated biomaterial for penile reconstruction in PD. The outcome of using Tutoplast is similar to that from saphenous vein but without the morbidity associated with the donor site. However, there remains a significant risk of penile shortening and development of erectile dysfunction.
