OBJECTIVE While transvaginal polypropylene mesh is increasingly used in the management of pelvic organ prolapse, contraction of the mesh after implantation may cause substantial morbidity. This report defines the clinical entity of vaginal mesh contraction. METHODS This is a case series of women who underwent surgical intervention for the management of symptomatic vaginal mesh contraction in ...

OBJECTIVE Mesh implants are widely used in surgery for female pelvic organ prolapse. Mesh shrinkage is thought to be common and caused by immunological processes. In this longitudinal study, we examined mesh dimensions at 2 time points after implantation. STUDY DESIGN We analyzed translabial 4-dimensional ultrasound (US) volume datasets of women seen 3-52 months after anterior compartment mes...

Due to the rapid evolution of 3D acquisition and modeling methods highly complex and detailed models became ubiquitous. In order to be able to cope with the complexity, concentrated efforts were dedicated to the development of new mesh decimation methods in the recent years. In works of Garland and Heckbert [Garland and Heckbert 1997] and Popović and Hoppe [Popović and Hoppe 1997], the traditio...

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. METHO...

In computer graphics rendering algorithms like ray tracing, the complexity of meshes decreases the performance of these algorithms. Therefore, the need arises for reduced mesh complexity with considerably good quality and at the same time preserving the salient features of the shape. Mesh simplification problem in some cases can be considered as an initial value problem where the quality of the...

In recent years, many new methods have been proposed for extracting curve skeletons of 3D shapes, using a mesh-contraction principle. However, it is still unclear how these methods perform with respect to each other, and with respect to earlier voxel-based skeletonization methods, from the viewpoint of certain quality criteria known from the literature. In this study, we compare six recent cont...

Mesh partitioning is often the preferred approach for solving unstructured computational mechanics problems on massively parallel processors. Research in this area has focused so far on the automatic generation of subdomains with minimum interface points. In this paper, we address this issue and emphasize other aspects of the partitioning problem including the fast generation of large-scale mes...

In this study, efficacy of two hernia mesh implants viz. conventional Prolene and a novel Prolene-Vicryl composite mesh was assessed for experimental ventral hernia repair in dogs. Twelve healthy mongrel dogs were selected and randomly divided into three groups, A, Band C (n=4). In all groups, an experimental laparotomy was performed; thereafter, the posterior rectus sheath and peritoneum were ...
