Is Robotic Prostate Surgery Better Than Traditional Surgery?

WSJ.com: WSJD - Technology

Advocates of robotically assisted prostatectomy argue that the procedure brings a number of advantages. Among them: less blood loss, shorter stays in the hospital and faster recovery times. However, it isn't clear that the robotically assisted procedures provide an advantage when it comes to survival rates and urinary and erection problems. And it costs significantly more. Ashutosh Tewari, system chairman of the department of urology at Mount Sinai Health System in New York City, believes the robotic surgery is better.


Worth the cost? A closer look at the da Vinci robot's impact on prostate cancer surgery

But the robot's US$2-million price tag and negligible effect on cancer outcomes is sparking concern that it's crowding out more affordable treatments. There are more than 5,500 da Vinci robots globally, manufactured by California-based tech giant, Intuitive. The system is used in a range of surgical procedures, but its biggest impact has been in urology, where it has a market monopoly on robot-assisted radical prostatectomies (RARP), the removal of the prostate and surrounding tissues to treat localized cancer. Uptake in the United States, Europe, Australia, China and Japan for performing this procedure has been rapid.


Computer-aided diagnosis prior to conventional interpretation of prostate mpMRI: an international multi-reader study

Nine radiologists (three each high, intermediate, low experience) from eight institutions participated. A total of 163 patients with 3-T mpMRI from 4/2012 to 6/2015 were included: 110 cancer patients with prostatectomy after mpMRI, 53 patients with no lesions on mpMRI and negative TRUS-guided biopsy. Readers were blinded to all outcomes and detected lesions per PI-RADSv2 on mpMRI. After 5 weeks, readers re-evaluated patients using CAD to detect lesions. Prostatectomy specimens registered to MRI were ground truth with index lesions defined on pathology.


Treatment for enlarged prostate uses a robot and a jet of water

ZDNet

Procept BioRobotics, a Silicon Valley-based surgical robotics company, recently raised nearly $120 million in private equity to commercialize a treatment for a prevalent prostate condition known as benign prostatic hyperplasia (BPH). BPH, also known as enlarged prostate, affects around half of men age 60 or older and 90 percent of men age 85 or older. Founded in 1999, Procept has pioneered the first commercially available autonomous tissue removal robot to treat BPH. The company's AQUABEAM system uses autonomous robotics and advanced imaging to deliver a heat-free waterjet that removes enlarged prostate tissue. The company has presented clinical research suggesting its method carries less risk of side effects than the current surgical gold-standard, known as TURP.


Rio Tinto achieves first autonomous train iron ore delivery

ZDNet

Rio Tino's autonomous train has completed its first delivery of iron ore in Western Australia's Pilbara. The train, consisting of three locomotives and described by Rio Tinto as "the world's largest robot", travelled over 280km from the company's mining operations in Tom Price to the port of Cape Lambert on Tuesday, July 10. The train was remotely monitored by Rio Tinto's Operations Centre in Perth more than 1,500km away. The locomotives are equipped with AutoHaul software and are fitted with on-board cameras for monitoring from the centre. "We will continue to ensure our autonomous trains operate safely under the wide range of conditions we experience in the Pilbara, where we record more than 8 million kilometres of train travel each year," said Ivan Vella, Rio Tinto Iron Ore managing director for Rail, Port and Core Services.
