Renal cell carcinomas are one of the most common types of cancer. In order to preserve its wide range of functions, every effort is made not to remove the entire kidney, but rather just a portion of it. A surgical method that preserves long-term renal function has now been carried out successfully for the first time in the Department of Urology at the MedUni Vienna and Vienna General Hospital.

A surgical ultrasound device is used that was previously used for liver cell carcinomas. In the pilot study, recently published in the highly respected journal "World Journal of Urology", this method has now been applied successfully at the Department of Urology at the Medical University of Vienna for the first time to the surgical treatment of complex renal tumours.

Patients benefit twice from the new technique: during the operation itself, the risk of bleeding and complications is lower. In the long term, renal function is preserved and there are no long-term consequences of renal impairment.

Until now, "cold ischaemia" has been used during the removal of renal tumours. With this method, the blood vessels supplying the kidney are clamped and the kidney is cooled. This is essential since the kidney bleeds very heavily when incised - and in humans, around 15 to 20 per cent of the entire blood supply is located in the two kidneys. "Cold ischaemia", however, has a serious disadvantage: the clamping of the vessels damages the renal vessels, significantly increasing the long-term risk of renal impairment.

Solution for a major surgical problem

This does not happen in procedures using the CUSA (Cavitron Ultrasonic Surgical Aspirator) ultrasound device, as study leader Shahrokh Shariat, Head of the  University Department of Urology at the MedUni Vienna and Vienna General Hospital, explains: "With the CUSA ultrasound device, the kidney continues to be perfused with blood during the surgical procedure. As our study shows, the new surgical technique allows renal function to be fully maintained, even though we can achieve the same oncological and surgical results as we do with clamping the organ. This has enabled us to resolve one of the major surgical problems of the last two decades."

Important renal functions remain intact

The problem of clamping and associated long-term damage only became apparent with the advances achieved in imaging with ultrasound and computed tomography. As a result of these advances, around 80 per cent of renal tumours are now detected so early that kidney-sparing treatment is possible without removal of the entire organ. The preservation of ideally both kidneys is important because the kidney performs a range of vital functions which diminish with age and as a result of kidney-damaging conditions such as diabetes and high blood pressure.

Dublin, July 13, 2015 (GLOBE NEWSWIRE) -- Research and Markets (http://www.researchandmarkets.com/research/bhvbgz/the_world_market) has announced the addition of the "The World Market for Dialysis Equipment and Services (United States, Japan, UK, Germany, France, Italy, India, China, Australia, Canada, Brazil, Mexico, South Africa, Russia and Other Nations)" report to their offering.

The dialysis industry enjoys a unique place in the healthcare sector with a comparatively small patient base but large revenue base for needed services. The industry encompasses the medical device industry (dialysis products and supplies segment) and the healthcare services industry (dialysis services segment). The stable customer base also explains how the dialysis industry is noncyclical in nature and is only minimally affected by the vagaries of economic downturns. This report looks at both the equipment and service aspects of the dialysis industry. The industry enjoys a unique place in the healthcare sector. The industry encompasses two very lucrative segments -- the medical device industry (dialysis products and supplies segment) and the healthcare services industry (dialysis services segment).

The dialysis industry remains a robust, multi-billion dollar business that has managed to fuel its growth engine in the past 5 years. What makes this market more interesting and challenging is its relatively small customer base - a bit under two million dialysis patients form its entire universe. It is the high value of these customers that make this a competitive industry. There are several key issues and trends impacting the future of the dialysis market. Demographics, insurance and reimbursement issues, and consolidation in the industry will continue to influence the outcome of the market in the future.

The report includes:

• Key Data and Analysis in this report includes:
• Detailed Forecasts to 2017
• In-Depth Profiles of the Competitive Companies in Dialysis Treatment, Equipment and Supplies.
• Scores of Figures and Tables featuring useful data, demographic and market trends that can be used to supplement internal memos or presentation.
• Detailed World Dialysis Market Review including specific reviews of the dialysis service, equipment and supplies market in the United States, Japan, UK, Italy, India, China and Australia and Canada.
• Market Share of Major Care and Equipment Providers.
• The Changing Regulatory Environment.
• Detailed Patient Demographics Current Data, Forecasts and Trends.
  

Issues and trends explored in this study include:

• Innovation Pathway at FDA
• Dialyzers
• Prismaflex System Software
• Wearable Artificial Kidney
• Implantable Artificial Kidney
• Prevalence of Diabetes in Developing Regions
• Insurance and Reimbursement Issues
• Access to Care for Native Populations
• Kidney Transplantation
• Product Development and Innovation
• Consolidation and Joint Ventures in the Industry
• Home Dialysis
• Heat Disinfection for Water Quality
• Dialysis Treatment Comfort
