The prostate is a small walnut-shaped gland in males that produces the seminal fluid that nourishes and transports sperm. Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer cells, and can then spread to other areas of the body. Prostate cancer begins when cells in the prostate gland start to grow out of control.
The prostate is a gland found only in males. It makes some of the fluid that is part of semen. The prostate is below the bladder (the hollow organ where urine is stored) and in front of the rectum (the last part of the intestines). Just behind the prostate are glands called seminal vesicles that make most of the fluid for semen. The urethra, which is the tube that carries urine and semen out of the body through the penis, goes through the center of the prostate.
Surgery is a common choice to try to cure prostate cancer if it is not thought to have spread outside the prostate gland. The main type of surgery for prostate cancer is a radical prostatectomy .
Robotic surgery, or robot-assisted surgery, allows doctors to perform many types of complex procedures with more precision, flexibility and control than is possible with conventional techniques. Typically, a few small incisions (about the diameter of a pencil) are needed. Surgeon controls the highly precise instruments attached to robotic arms during the entire operation. Surgeon can clearly see the tissues and nerves in 3D-HD with up to 10x magnification. Surgeon can reach tissues from many angles to remove the prostate and cancer cells precisely. Surgeon can carefully work around the nerves that control erections when indicated. Often, robotic surgery makes minimally invasive surgery possible. The benefits of minimally invasive surgery include:
Fewer complications, such as surgical site infection:* Less pain and blood loss
Using the advanced surgical system, miniaturized robotic instruments are passed through several small keyhole incisions in the patient’s abdomen to allow the surgeon to remove the prostate and nearby tissues with great precision. During robotic-assisted radical prostatectomy, a three-dimensional endoscope and image processing equipment are used to provide a magnified view of delicate structures surrounding the prostate gland (e.g., nerves, blood vessels and muscles), allowing optimal preservation of these vital structures. The prostate is eventually removed through one of the keyhole incisions.
Laparoscopic surgery differs from traditional open surgery by making five small incisions as opposed to one large one to perform the surgery. Surgical tools and a camera are inserted through the incisions, and radical prostatectomy is performed from outside the body. The surgeon views the entire operation on a video screen. This leads to less abdominal trauma, better cosmetic outcomes, and typically a faster recovery process.
