Robot-assisted surgeries prevent erectile dysfunction

In the last decade, minimally invasive surgery has widely entered the global urological practice. The first attempts to create remotely controlled surgical robots date back to the 80s of the 20th century under a program of the National Aeronautics and Space Administration. In recent years, the US Department of Defense has been developing a program for remote surgery by a surgeon on wounded soldiers on the battlefield with the goal of reducing their mortality. These developments became the basis of modern surgical robotic systems. The Da Vinci telerobotic surgery system was created in 1999 and was first used by cardiac surgeons. Over the next 10 years, the number of robotic systems in the world grew exponentially. After 2002, robotic surgery rapidly entered global urological practice. For several years in the United States, it became the most preferred method of surgical treatment for prostate cancer by patients and urologists. In 2011, 85% of prostate cancer surgeries in the US were already performed with the DaVinci robotic system. One of the main applications of robotic systems in urology is in operations for carcinoma of the prostate gland, which in 2013 was the most common type of cancer in men – 15%. Statistically, it is estimated that every 2 and a half minutes a new cancer patient is diagnosed, and every 16 minutes a patient dies of this disease. In Bulgaria in the last 2 years there has been an increased morbidity. Robotic surgery gives us the opportunity to overcome the mentioned difficulties and achieve optimal results through its advantages. A three-dimensional image with the highest resolution and clarity is possible with up to 15x magnification of the surgical field. Control of fine tools with precise movements via a console is used. In turn, the robotic system repeats the movements in a ratio of 3-5 to 1, reducing the possibility of wrong movements and protecting against the possibility of possible errors. Another advantage of robotic surgery is that it allows the surgeon to operate with increased dexterity and precision with miniaturized instruments, which are especially important in neuro-sparing surgery. The recovery period is also significantly shortened. In patients who have undergone this type of surgery, there is a reduction in blood loss, as well as the need for blood transfusion. There are no extensive incisions, which in turn significantly reduces the need for anesthesia. Early return to full physical activity and work capacity is another important detail of the application of robotic surgery. A number of non-randomized studies and publications have reported better functional outcomes – preservation of erectile function in robotic surgery. According to more and more authors, there is an advantage of the method also in terms of oncological results (positive surgical margins, biochemical recurrence, survival),which also needs to be confirmed by long-term randomized trials that are in progress.
