Robotic Cystectomy for Bladder Cancer

Robotic surgical systems have thrust minimally invasive surgical options into a new era. For years, surgeons and urologic oncologists have relied on the minimally invasive, nerve-sparing virtues of the procedure known as laparoscopic cystectomy to offer their patients the most effective treatment for bladder cancer. Not long ago, all cystectomies were performed using an open surgical procedure in which notable tissue and nerve damage, significant blood loss, and an increased risk of post-operative infections and complications were common.

Robotic cystectomy is simply a newer, more effective, minimally invasive surgical method for bladder cancer. This procedure utilizes the da Vinci Surgical System in which a robotic arm imitates the surgeon’s movements, amplifying their precision. It offers bladder cancer patients the prospect of a more effective surgery and less problematic post-surgical recovery. It is fast becoming the preferred answer for bladder cancer surgery. This surgical procedure allows the surgeon to make smaller incisions which spare vital, but delicate, nerve and muscle tissue. The patient experiences a shorter hospital stay, fewer complications, and a faster recovery time.

Laparoscopic Cyctectomy
Similar to a standard laparoscopic cystectomy, the robotic-assisted cystectomy may require a urinary diversion with subsequent reconstruction for the removed bladder. For men and women alike, such reconstruction would include a continence reservoir which holds urine in the abdominal cavity until the patient has been fitted with a catheter to empty urine or a bladder replacement and an external bag for urine collection. The da Vinci Surgical System provides the physician with a superior visualization plane and improved surgical dexterity during bladder removal and, if necessary, a reconstructive procedure.

By offering the surgeon, urologist or oncologist a high-definition 3-D view, the da Vinci surgical robot distinguishes the vital muscles and delicate nerve tissues surrounding the operative area, providing the opportunity to preserve them. The robot’s unique EndoWrist instruments offer physicians the dexterity not available to them when using conventional laparoscopic instruments. By taking advantage of the da Vinci robot, surgeons are able to dissect and reconstruct the bladder with relative ease.

Summary of Robotic-Assisted Cystectomy:

  • Designed to spare delicate nerve and muscle tissue.
  • Keyhole-sized incisions distributed across the abdomen.
  • A brief 4 to 7 day hospital stay.
  • Less risk of blood loss and a lower chance of needing a blood transfusion.
  • Reduced scarring, minimal discomfort, and less need for major pain medication.

Only one to three month's period of recovery before regaining a normal level of urine control.

Cancers of the bladder are usually diagnosed by examining urine for cancer cells under a microscope (known as urine cytology) or during cystoscopy, an inspection of the bladder by inserting a slender tube equipped with a lens and a light through the urethra up to the bladder.

What should i do if my lawn mower turns into a robot and runs off | ChaCha

You should notify Transformers director Michael Bay that you have a real life Transformer on your hands and he should film it!

What would happen if my lawn mower turned into a robot menue?

If your lawn mower became a robot then it would mow and you wouldn't. It would do all the work and you could relax.
