da Vinci® Robotics for Prostate (Prostatectomy)

When medication and other non-surgical treatments are either unavailable or cannot relieve symptoms, surgery is the accepted treatment for a broad range of conditions that affect the male reproductive organs and the organs of the urinary tract. These conditions include, but are not limited to, prostate cancer, ureteropelvic junction (UPJ) obstruction, bladder and kidney cancer and vesicoureteral reflux.

Facing any kind of urologic surgery creates a great deal of anxiety for most men. Among your concerns is: "Will my body function normally following surgery?" Traditional open urologic surgery – in which large incisions are made to access the pelvic organs – has been the standard approach when surgery is warranted. Yet common drawbacks of this procedure include significant post-surgical pain, a lengthy recovery and an unpredictable, potentially long-term impact on continence and sexual function.

Fortunately, less invasive surgical options are available to many patients facing urologic surgery. The most common of these is laparoscopy, which uses small incisions. While laparoscopy can be very effective for many routine procedures, limitations of this technology prevent its use for more complex urologic surgeries.

A new category of surgery, introduced with the development of the da Vinci® Surgical System, is being used by an increasing number of surgeons worldwide for prostatectomy and other urologic procedures. This minimally invasive approach, utilizing the latest in surgical and robotics technologies, is ideal for delicate urologic surgery. This includes prostatectomy, in which the target site is not only tightly confined but also surrounded by nerves affecting urinary control and sexual function. Using da Vinci®, your surgeon has a better tool to spare surrounding nerves, which may enhance both your recovery experience and clinical outcomes.

Prostate Cancer

Prostate cancer is a disease in which malignant (cancer) cells form in the tissues of the prostate. The prostate is a gland in the male reproductive system located just below the bladder and in front of the rectum. It is about the size of a walnut and surrounds the urethra (the tube that empties urine from the bladder). The prostate gland produces fluid that is a component of semen.

Approximately 16% of U.S. men will be diagnosed with prostate cancer sometime in their lives. Treatment options and prognosis depend on the stage of the cancer, the Gleason score, and the patient’s age and general health.

The most common patient scenario is the man with clinically localized disease (classified as stage T1 or T2) with no regional lymph node or distant metastasis. According to the American Urological Association, of the 234,460 men in the United States diagnosed with prostate cancer annually, 91% have localized disease.

With greater public awareness, early detection is on the rise and mortality rates are declining. Additionally, new advances in medical technology are enabling cancer patients to go on to live active and productive lives after their treatment. Patients should always consult with their doctor for advice on the options that are available to treat their individual condition.

Treatment Options for Prostate Cancer

When prostate cancer is believed to be still localized within the prostate gland, there are essentially five treatment options available to a patient:

  • Observation (watchful waiting)
  • Hormonal therapy (non curative)
  • Removal of the cancerous prostate (radical prostatectomy)
  • Radiation of the cancerous prostate (either external radiation or radioactive seed implants)
  • Freezing of the cancerous prostate (cryosurgery)

Patients should discuss the advantages and disadvantages of each treatment approach with their doctor. For localized prostate cancer, radical prostatectomy (surgical removal of the prostate and surrounding cancerous tissues) has historically been considered the “gold standard” or definitive way to remove the cancer.

da Vinci® Prostatectomy: Introduction

da Vinci® Prostatectomy is an effective, minimally invasive approach to surgical treatment of prostate cancer.

This method incorporates the latest advancements in robotic-assisted technology and allows a surgeon greater visualization, dexterity, precision and control as well as superior ergonomics. The da Vinci® Surgical System is a sophisticated robotic platform designed to enable complex surgery through small incisions. The da Vinci® System consists of a surgeon’s console, a patient side cart with up to four interactive robotic arms, a high-performance 3D high definition vision system and EndoWrist® instruments which enhance the possible range of motion.

Powered by state-of-the-art robotic technology, the da Vinci® System is designed to scale, filter and seamlessly translate the surgeon's hand movements into more precise movements of the EndoWrist instruments. The net result is an intuitive interface with enhanced surgical capabilities.

da Vinci® Surgical System instruments are approximately the diameter of a pencil and are unique due to their articulating wrist architecture. The precision this innovative design enables in delicate surgery is unsurpassed.

da Vinci Robotic Surgery

For qualified candidates, da Vinci® Prostatectomy offers numerous potential benefits over traditional open prostatectomy, including:

  • Shorter hospital stay
  • Less pain
  • Less risk of infection
  • Less blood loss and fewer transfusions
  • Less scarring
  • Faster recovery
  • Faster return to normal activities

da Vinci Prostatectomy Incisions

da Vinci® Prostatectomy received FDA clearance for prostate cancer surgery in the U.S. in May 2001. Since then, the preference of patients and surgeons for the da Vinci approach to radical prostatectomy has grown to over 100,000 procedures performed. da Vinci Prostatectomy is now the #1 treatment choice for prostate cancer in the United States.

Candidates for da Vinci® Prostatectomy

Every surgical candidate should be considered individually in consultation with their urologist. Good candidates for da Vinci Prostatectomy will usually be men with localized disease who have optimal potential for long-term survival post-treatment. Prior surgery and obesity can add challenges to the procedure, but do not necessarily rule out a man as a candidate. Men should also discuss whether the location and staging of their prostate cancer allows for a nervesparing procedure (either bilateral or unilateral).

da Vinci® Prostatectomy: Procedure

Radical prostatectomy is a complex and delicate procedure due to many factors, including the location of the prostate gland deep inside the pelvis. In radical prostatectomy, the surgeon removes the entire prostate gland along with both seminal vesicles, both ampullae (the enlarged lower sections of the vas deferens), as well as additional surrounding tissues. The surgeon may be able to spare the nerves that run on both sides near the prostate, known as the neurovascular bundles, which can help preserve potency and urinary continence. The section of urethra that runs through the prostate is cut away, and the bladder is re-attached to the remaining section of urethra.

Potential advantages of da Vinci® Prostatectomy

In the United States today, surgeons use one of three approaches to radical prostatectomy: open surgery, laparoscopic surgery and robotic-assisted laparoscopic surgery, of which the latter two are minimally invasive. An open prostatectomy requires a 5-7 inch incision in the patient’s abdomen for direct access to the operative site. Conventional laparoscopic and robotic-assisted laparoscopic approaches require several dime-sized incisions, or operating “ports,” which are used to introduce narrow-shafted instruments. The surgeon and assistants maneuver the instruments from outside the body, under vision provided by a surgical camera. The potential advantages of laparoscopic and robotic-assisted laparoscopic prostatectomy (da Vinci® Prostatectomy) over conventional open surgery include smaller incisions for less postoperative pain and improved cosmetics, reduced blood loss and less need for blood transfusions, as well as a faster return to normal activities.

The two major drawbacks of conventional laparoscopy are its reliance on the use of rigid, hand-held instruments and visualization provided by a standard 2D video monitor. While these technologies enable smaller incisions, they can limit the surgeon’s depth perception, as well as his/her dexterity and precision. Standing at the patient’s side, the surgeon must operate in a counterintuitive fashion, moving the long-shafted instrument handle in precisely the opposite direction of where he or she intends to move the instrument tip. The surgeon maneuvers the instruments while looking up at the 2D view of the operating field projected on a tableside video monitor and must instruct an assistant on how to position the surgical camera.

In contrast, da Vinci® Prostatectomy (dVP) incorporates state-of-the-art video and robotic technologies that provide natural depth perception and allow a surgeon’s hand movements to be scaled, filtered and translated into precise micro-movements of tiny instruments at the operative site. The superior visualization, enhanced dexterity, precision and control enable the surgeon to perform complex procedures — like radical prostatectomy — through dime-sized operating “ports.” For most patients, da Vinci® Prostatectomy offers substantially less pain and a shorter recovery period than traditional prostate surgery. Other advantages may include reduced need for blood transfusions, less scarring and lower risk of infection. In addition, recent studies suggest that da Vinci® Prostatectomy may offer improved cancer control and a lower incidence of impotence and urinary incontinence.

Additionally, da Vinci® has allowed many surgeons to effectively use nerve-sparing techniques with radical prostatectomy to reduce the risk of impotence and urinary incontinence.

Potential disadvantages of da Vinci® Prostatectomy

While clinical studies support the use of the da Vinci® Surgical System as an effective tool for minimally invasive surgery, individual results may vary. da Vinci® Prostatectomy remains a surgical procedure, and as such carries inherent risks. Though data supports high rates of cancer control, maintaining sexual function and return to urinary continence, there is no guarantee of these benefits to every patient. Also, some individuals may not be candidates for a full nerve-sparing procedure due to the extent of their cancer. Results, as with the open operation, are surgeon-dependent and improve significantly with surgeon experience in this surgical modality.
