Computer-assisted robotic renal surgery (CARRS) is a minimally invasive surgical treatment option for renal tumors. We review the literature regarding techniques and outcomes and the potential advantages of CARRS. We retrospectively reviewed the literature regarding techniques and outcomes of CARRS, with specific analysis on robotic radical nephrectomy (RRN) and robotic partial nephrectomy (RPN...

PURPOSE To compare the perioperative outcomes of laparoscopic partial nephrectomy (LPN) and robotic partial nephrectomy (RPN) for moderately or highly complex tumors (RENAL nephrometry score ≥ 7). MATERIALS AND METHODS A retrospective analysis was performed for 127 consecutive patients who underwent either LPN (n=38) or RPN (n=89) between 2007 and 2013. Perioperative outcomes were compared. ...

OBJECTIVE To compare the utilization, perioperative complications and predictors of LCA versus RPN in the treatment of localized renal tumors. METHODS From the Nationwide Inpatient Sample we identified patients undergoing RPN or LCA for the treatment of localized renal tumors from October 2008 through 2010. Patient and hospital-specific factors which predict postoperative complications and us...

BACKGROUND The objective of this study was to evaluate the impact of metastasis to the retropharyngeal nodes (RPN) in CT-based lymph node-positive head and neck patients by comparing other node levels. PATIENTS AND METHODS A total of 175 CT-based lymph node-positive patients with carcinoma of the head and neck were managed with definitive radiation therapy. RPN involvement was identified only...

Risk-mitigation decisions in risk-management systems are usually based on complex risk indicators. Therefore, aggregation is an important step during assessment. Aggregation when determining the of components or overall different areas organizational levels. In this article, authors identify scenarios. They summarize requirements functions and characterize aggregations according to these requir...

Failure mode effects and criticality analysis (FMECA) is a commonly adopted approach to defining, assessing, reducing possible failures in designs, systems, processes, products, services. Traditional FMECA ranks the failure modes of products based on risk priority number (RPN), which obtained by multiplying elements. Conventional has shortcomings badly handling unknown information unreasonably ...

In this paper, reliability block diagram of a sounding rocket separation system is determined and also, FMEA analysis of its spring mechanism is performed. This system is based on the flexible linear shape charge crosssection system and a spring mechanism to accelerate separation. In this investigation, reliability block diagram of the separation system include mechanical and electrical mechani...

Abstract Study question Can integration of a robotic system for semen analysis reduce operational failure modes and eliminate risk in the IVF laboratory? Summary answer A reduces eliminates severe risks including those associated with reduced patient experience increased stress. What is known already Recently, ever-evolving field has experienced rise innovations to boost laboratory performance....

INTRODUCTION In any complex human system, human error is inevitable and shows that can't be eliminated by blaming wrong doers. So with the aim of improving Intensive Care Units (ICU) reliability in hospitals, this research tries to identify and analyze ICU's process failure modes at the point of systematic approach to errors. METHODS In this descriptive research, data was gathered qualitative...
