Abstract Male urethral stricture disease is one of the common conditions encountered in the day-to-day urological practice. It can present at any age and has a wide range of etiological factors including infection, trauma and instrumentation. It usually manifests itself as lower urinary tract symptoms or urinary tract infections with signifi cant impairment in the quality of life. There are several treatment options for this condition and these mainly depend on the site, length, the underlying cause and previous treatment. The management of bulbar urethral strictures has greatly evolved over the last few decades with more More >

Abstract Introduction: Prostate cancer presents a global public health dilemma. While screening with prostate specific antigen (PSA) has led to more men diagnosed with prostate cancer than in previous years, the potential for negative effects from over-diagnosis and treatment cannot be ignored.
Materials and methods: We reviewed Medline for recent articles that discuss clinical trials, evidence based recommendations and guidelines from major medical organizations in the United States and worldwide concerning prostate cancer screening.
Results: Results from the European Randomized Screening for Prostate Cancer (ERSPC), the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial, and Göteborg Swedish trials… More >

Abstract Fuel cell technology one of the hottest topics in the green energy industry and has become a popular topic in most of the international green energy symposiums. In the meantime,the development of the fuel cell industry has been recognized as one of the key rising industries in Taiwan. Since 2009,the Industrial Technology Research Institute(ITRI) has collaborated with Chung-Hua Institution for Economic Research(CIER) for implementing the fuel cell demonstration and promotion programs which are supported by the Bureau of Energy, Ministry of Economic Affairs. This program focuses on three major areas for application of fuel cells:backup… More >

Abstract The symptoms of overactive bladder (OAB) -- urinary urgency, frequency, and urge incontinence -- can cause signifi cant lifestyle limitations. Social isolation, depression, employment diffi culties, and relationship stress are common fi ndings in patients with this condition. This article focuses on women with OAB who are seen in primary care. Occasionally, OAB (or detrusor overactivity) may be the result of neurological disease, metabolic disease, or urinary tract abnormalities. Primary care practitioners can play a key role in identifying affected individuals by including a focused question in every annual patient physical assessment. Investigation and treatment More >

Abstract Aim: To review the global select data on the current technique, perioperative outcome and literature on the robot-assisted pyeloplasty (RAP).
Methods: The published English literature (PubMed) was extensively searched using the key words; robot, robot-assisted pyeloplasty, laparoscopy, laparoscopic pyeloplasty and ureteropelvic junction obstruction. The selected studies were then reviewed, tracked and analyzed in order to determine the current role, outcome and status of robot-assisted laparoscopic pyeloplasty.
Results: The search yielded about 25 published series on RAP comprising about 740 cases with a mean operative time, estimated blood loss, crossing vessel prevalence, hospital stay, perioperative complication rate and follow More >

Abstract Background: Needle biopsy of the prostate is a common outpatient procedure. In March 2009, the European Association of Urology (EAU) published an updated, evidence-based "Guidelines on Prostate Cancer," including recommendations for this procedure.
Objective: To survey onco-urology specialists attending the 6th European Section of Oncological Urology (ESOU) meeting in Istanbul, Turkey in January 2009, to assess their biopsy practices and compare them with March 2009 EAU guidelines.
Design, setting and participants: The authors designed a questionnaire and distributed it to 606 conference delegates. It was completed by 298 delegates, of whom 156 were experienced onco-urological specialists.
Measurements: The survey… More >

Abstract Natural orifi ce transluminal endoscopic surgery (NOTES) has attracted considerable recent attention for its potential to allow traditional abdominal procedures to be performed without a transabdominal incision. With considerable experience in the development and application of minimally invasive techniques, urologists have played a signifi cant role in early experimental NOTES efforts and have contributed to early investigations in human subjects accordingly. However, adoption of these techniques has been limited due to cumbersome endoscopic equipment and concerns regarding peritonitis from failed viscerotomy closure. Experience with use of NOTES in human subjects is limited, and studies comparing More >

Abstract The concurrent methods for coupling molecular dynamics with continuum thermodynamics offer a myriad of challenging problems, mostly related with energy transmission, wave reflection, and damage propagation at the interfaces between the continuum description and the discrete description. In this work, by virtue of the atomistic field theory (AFT), we present an analysis to reconcile the compatibility between atomic region and continuum region and to calculate the matching temperature field of a heat conduction problem in a concurrent atomistic/continuum system. First, formulation of AFT with finite temperature and its corresponding finite element implementation are briefly introduced. More >

Abstract The systematic potential design is of high importance in computational electromagnetics. For example, it is well known that when the efficient eddy-current formulations based on a magnetic scalar potential are employed in problems which involve conductive regions with holes, the so-calledthick cutsare needed to make the boundary value problem well defined. Therefore, a considerable effort has been invested over the past twenty-five years to develop fast and general algorithms to compute thick cuts automatically. Nevertheless, none of the approaches proposed in literature meet all the requirements of being automatic, computationally efficient and general. In this More >

Abstract Background. The efficacy of percutaneous coronary intervention (PCI) is limited by the need for repeat revascularization resulting from restenosis. The restenosis rate after treatment for in-stent restenosis (recurrent restenosis) is high (> 30%). Numerous studies have suggested the predictive value of interleukin 6 (IL-6) and transforming growth factor β1 (TGF-β1). Methods. We sought to determine whether serum levels of IL-6 and TGF-β1 could help identify individuals with recurrent restenosis. Thirty seven patients with a history of stent implantation were enrolled and divided into three groups: (1) patients with a current, first restenosis (n = 9);… More >
