OBJECTIVES Tension-free vaginal tape has gained large popularity owing to the ease of the procedure and its effectiveness. These procedures were initially thought to rarely involve any significant morbid complications. The transobturator tape (TOT) procedure reproduces the natural suspension similar to the tension-free vaginal tape with a reduction in potential bladder, bowel, and vascular comp...

OBJECTIVE To identify possible risk factors for exposure, dyspareunia, and pain after insertion of tension-free vaginal mesh in pelvic organ prolapse surgery. METHODS This was a prospective observational cohort study. Consecutive women who underwent surgery with a trocar-guided tension-free vaginal mesh kit were included and evaluated at 6 weeks and at 6 and 12 months after surgery with respe...

We consider problems involving high-speed moving rigid objects in a fluid flow. Instead of a more traditional deformable mesh approach, we describe a novel fixed mesh approach which use a level set function to implicitly track the fluid-solid interface, therefore no mesh motion or modification is required. The interface boundary conditions are also captured implicitly by combining a Ghost Fluid...

this paper presents the results of numerical simulations of the laminar and turbulent flows inside diverging channels using random vortex methods (rvm). random vortex method is a mesh-free method which solves unsteady vorticity equation instead of solving navier-stokes equations directly to determine the velocity field. in this paper, the velocity potential, which is used as the initial conditi...

This study aimed to compare the effects of polypropylene (PP), lightweight PP (UP) and expanded polytetrafluorethylene (e-PTFE) hernia mesh on the reproductive function of adult male Sprague-Dawley (SD) rats following open tension-free hernioplasty. Forty adult SD rats were obtained and divided into five groups: A sham-operated (FO) group, an e-PTFE mesh group, a PP mesh group, the UP mesh grou...

BACKGROUND Evaluation of cost-effectiveness of new surgical techniques is important. As the data on incontinence procedures are scarce, we evaluated the cost-effectiveness of tension-free vaginal tape procedure and laparoscopic mesh colposuspension as a primary surgical treatment for female stress urinary incontinence. METHODS In four university teaching hospitals and two central hospitals 12...

A scheme using the mesh-free generalized finite differencing (GFD) on flows past moving bodies is proposed. The aim is to devise a method to simulate flow past an immersed moving body that avoids the intensive remeshing of the computational domain and minimizes data interpolation associated with the established computational fluid methodologies; as such procedures are time consuming and are a s...

We investigated four key aspects of forward models for distributed solutions to the MEG inverse problem: 1) the nature of the cortical mesh constraining sources (derived from an individual's MRI, or inverse-normalised from a template mesh); 2) the use of single-sphere, overlapping spheres, or Boundary Element Model (BEM) head-models; 3) the density of the cortical mesh (3000 vs. 7000 vertices);...

A technique for performing progressive mesh-based motion estimation in a layered fashion is presented. Motion compensation based on image warping provides a block prediction free of block artifacts. The smooth prediction can be used to identify motion-active regions by comparing with the reference frame and generate a partial denser mesh, thus forming layers of mesh. This approach provides a hi...
