The surgical management of female stress urinary incontinence (SUI) has evolved over the past century, using various techniques of retropubic colposuspensions and sling procedures. In the past two decades, the sling has become the mainstay of surgical treatment of SUI, with the synthetic midurethral sling (MUS) leading the way. With the recent concerns raised by the U.S. Food and Drug Administration (FDA) and Health Canada about the safety of vaginal surgery using mesh implants, including the MUS, urologists and gynecologists should be familiar with suitable alternatives, including the pubovaginal sling (PVS), which often incorporates autologous fascia...

Recent data has demonstrated a one in five lifetime risk of a woman requiring stress urinary incontinence (SUI) surgery. Currently, most women opt for a synthetic midurethral sling (MUS), with over 3.6 million placed worldwide. This article attempts to identify whether a gold standard exists with regards to surgical correction of female SUI. When considering which sling type to use for which incontinent woman, the published data demonstrates excellent results for both synthetic mesh (retropubic or transobturator routes) and fascial pubovaginal slings for most patients...

Collecting large databases of annotated medical images is crucial for the validation and testing of feature extraction, statistical analysis and machine learning algorithms. Recent advances in cardiac electromechanical modeling and image synthesis provided a framework to generate synthetic images based on realistic mesh simulations. Nonetheless, their potential to augment an existing database with large amounts of synthetic cases requires further investigation. We build upon these works and propose a revised scheme for synthesizing pathological cardiac sequences from real healthy sequences...

OBJECTIVES: Synthetic mesh surgery for both abdominal and urogenital hernia repair is often unsatisfactory in the long-term due to postoperative complications. We hypothesized that a semi-degradable mesh hybrid may provide more appropriate biocompatibility with comparable mechanical properties. The aim was to compare its in vivo biocompatibility with a commercial polypropylene (PP) mesh. METHODS: 72 rats were randomly allocated to either our new composite mesh (monofilament PP mesh knitted with polylactic-acid-fibers (PLA)) or to a commercially available PP mesh that was used as a control...

Nano-hemostats are synthetic amino acid chains that self-assemble into a scaffold under certain conditions. These have been shown to be effective in stopping bleeding in small animal models of hemorrhage. Proposed mechanisms for their effect are that they form a mesh analogous to the fibrin plug in native hemostasis and that they may potentiate both platelet activation and the coagulation cascade. These may potentially become valuable adjuncts to endoscopic skull base surgery where there is the potential for both major vessel injury and smaller perforator injury to eloquent areas where bipolar cautery may not be suitable...

BACKGROUND AND AIM: In the age of synthetic prostheses most of hernia studies include a careful examination of the various types of prosthesis, their characteristics and their repair indications. Biological prostheses are also beginning to draw attention. But in terms of recurrence especially for poor or developing countries, the discussion is different, due to their high cost which makes them difficult to afford. In this article we present new flap reconstruction techniques for the reconstruction of the abdominal wall versus mesh repair, applied on swine models, outline the results of each technique, and specify the indications for their use...

With current technological advancement and availability of synthetic materials used in inguinal hernia repair, a recurrence after first intervention is not a common and important adverse event. On the other hand, however, some patients complain about chronic pain of the operated site after surgeries using a polypropylene mesh. Many patients are constrained to a prolonged use of analgesics and increased frequency of control visits, which may eventually result in loss of trust in the operator. Every surgical intervention is associated with the risk of immediate or delayed complications...

Although accurate and robust estimations of the deforming cardiac geometry and kinematics from cine tomographic medical image sequences remain a technical challenge, they have significant clinical value. Traditionally, boundary or volumetric segmentation and motion estimation problems are considered as two sequential steps, even though the order of these processes can be different. In this paper, we present an integrated, spatiotemporal strategy for the simultaneous joint recovery of these two ill-posed problems...

We directly track the tubelike motion of individual fluorescently labeled polymer molecules in a concentrated solution of unlabeled polymers. We use a single molecule wide-field fluorescence microscopy technique that is able to determine characteristic properties of the polymer dynamics, such as the confining potential, the tube diameter, and the Rouse time. The use of synthetic polymers allows us to investigate the confined motion of the polymer chains not only as a function of polymer concentration (mesh size) but also versus the persistence length of the matrix polymers...

Prosthetic reinforcement reduces the recurrence rate of large paraesophageal hernias (PEH), but the use of synthetic or biosynthetic mesh in the repair remains controversial. PEH repair has reported recurrence rates of 12% to 42%, and primary repair of PEH by suture closure under tension is at high risk of disruption. Synthetic mesh use in large PEH repair has shown to reduce recurrence but can lead to problems including mesh erosion, ulceration, stricture, and dysphagia. The objective of this study was to examine the long-term safety and efficacy of Strattice biologic mesh, a porcine acellular dermal matrix, in crural reinforcement of laparoscopic large PEH repair...
