Robotic surgery in the treatment in certain urological diseases has become a mainstay. With the increasing use of the robotic platform, some surgeries which were historically performed open have transitioned to a minimally invasive technique. Recently, the robotic approach has become more utilized for ureteral reconstruction. In this article, the authors review the surgical techniques for a number of major ureteral reconstuctive surgeries and briefly discuss the outcomes reported in the literature.

Primary chest wall tumours are very rare. Chondrosarcoma is the most common tumour arising from the chest wall. We describe the occurrence of a slow-growing chondrosarcoma arising from the anterior chest wall in a 35-year-old male patient. The tumour was resected successfully and chest wall was reconstucted with prolene mesh and muscle flap. The patient was discharged uneventfully without any respiratory compromise. There was no recurrence after a three-year follow-up. Wide surgical resection with chest wall reconstruction appears to be the preferred treatment option for this rare tumour of the chest wall...

Currently, there are lots of methods to select informative SNPs for haplotype reconstruction. However, there are still some challenges that render them ineffective for large data sets. First, some traditional methods belong to wrappers which are of high computational complexity. Second, some methods ignore linkage disequilibrium that it is hard to interpret selection results. In this study, we innovatively derive optimization criteria by combining two-locus and multilocus LD measure to obtain the criteria of Max-Correlation and Min-Redundancy (MCMR)...

The pectoralis major myocutaneous flap (PMMC flap) represents a landmark in the development of head and neck reconstructive surgery. After Stephan Ariyan first described its use for head and neck reconstruction in 1979, it has become tremendously popular and has revolutionised head and neck cancer surgery. Here, we present our initial experience with fourteen PMMC flaps in head and neck reconstruction. In most of the instances it was used for oral or oropharyngeal reconstruction. It was used for five other reconstructive tasks as well...

Diffraction in the Fourier-transform infrared spectrometer based on step mirrors was analyzed in the present paper, and the influence of diffraction on the spectrum reconstruction with different width of step mirrors, wavelengths and distance was also discussed. It is shown that the influence of diffraction is low when the distance is less than 10 cm and the width of mirror is more than 0.5 mm. Also, a method to reduce the noises in spectrum reconstuction is discussed in this paper. The results could be used in the design of the spectrometer and the data processing in the next step...

We have developed a tomosynthesis-based radioactive seed localization method for prostate brachytherapy. In contrast to the projection image-based matching approach, our method does not involve explicit segmentation of seeds and can recover hidden seeds. Modified distance map images are computed from a limited number of x-ray projection images, and are backprojected to reconstuct a 3-D volume of interest. Candidate seed locations are extracted from the reconstructed volume and false positive seeds are eliminated by solving an optimal geometry coverage problem...

BACKGROUND: Superior vena cava syndrome (SVCS) is a rare complication of pacemaker implantation. Numerous methods have been employed to treat this condition, ranging from anticoagulation and thrombolysis to surgical interventions and stenting. However, thus far only small case series have been reported and there is no currently accepted standard of care. METHODS: Our group preformed a PubMed literature search to identify cases of symptomatic SVCS that developed following implantation of permanent pacemakers or implanatable cardioverter defibrillators and were treated with one of five different modalities: anticoagulation, thrombolysis, venoplasty, stenting, and surgical reconstuction...

Knee rotationplasty was initially proposed for the reconstruction of the knee joint in the congenital hypoplasia of the femur. Its application was extended to functional reconstruction of the knee joint after wide resection of malignant bone or soft tissue tumor around the knee. It has also been shown to salvage a failed knee-sparing surgery due to infection or the aseptic loosening of the prosthesis. Hip rotationplasty has been described as a method for the reconstuction of hip function, as well as in the knee joint, in the case of a primary malignant tumor of the proximal part of the femur in children...

The reconstruction of maxillofacial bone defects by the intraoperative modeling of implants may reduce the predictability of the esthetic result, leading to more invasive surgery and increased surgical time. To improve the maxillofacial surgery outcome, modern manufacturing methods such as rapid prototyping (RP) technology and methods based on reverse engineeing (RE) and medical imaging data are applicable to the manufacture of custom-made maxillary prostheses. After acquisition of data, an individual computer-based 3D model of the bony defect is gernerated...

An accurate, computationally efficient, and fully automated algorithm for the alignment of two-dimensional (2-D) serially acquired sections forming a three-dimensional (3-D) volume is presented. The approach relies on the optimization of a global energy function, based on the object shape, measuring the similarity between a slice and its neighborhood in the 3-D volume. Slice similarity is computed using the distance transform measure in both directions. No particular direction is privileged in the method avoiding global offsets, biases in the estimation and error propagation...
