First thing’s first: What is a prostatectomy?

Radical prostatectomy refers to the operation to remove the prostate gland and the tissue around it. Usually, it’s recommended for men younger than 75 who have prostate cancer and are expected to live at least 10 more years with the condition.

If you have prostate cancer but it hasn’t spread beyond your prostate, there’s a good chance this surgery could cure you completely. However, like any surgery, it comes with a low risk of more serious complications.

So, what is minimally invasive prostatectomy?

Over the last few decades, the development of robot-assisted technology has slowly changed how doctors treat patients with cancer.

At Mount Elizabeth Hospital, the robot used to treat prostate cancer is one of the most technologically advanced in the world. It features a high-definition 3D camera and robotic arms controlled by a state-of-the-art console. It is also capable of removing the entire prostate by making only a few small incisions in the tummy area.

The robot gently frees the prostate from the bladder and urethra (water pipe), minimising the risk of damage to the surrounding nerves that control your urge to go to the toilet, as well as the risk of damage to the nerves that control your erection.

What are the benefits of minimally invasive prostatectomy?

Minimally invasive prostatectomy - Benefits
First of all, this high-tech robot gives your surgeon unprecedented control in the operating theatre.

Sitting down, your surgeon can move all of the robotic arms at the same time while using the camera to really focus on the area that needs surgery. Miniature surgical instruments mimic your surgeon’s instructions precisely, minimising the room for error in the confined space of your pelvis.

“These intuitive hand controls give surgeons an additional degree of freedom as well as finer hand control,” says Dr Tan. “The advanced 3D viewing monitor also means we can magnify the area and consider all angles when carefully removing the prostate itself.”

But beyond assisting the surgeon in the operating theatre, why is a minimally invasive prostatectomy such a good thing?

“Conventionally, open surgery means a much bigger incision needs to be made in your tummy, resulting in slower recovery times and a longer stay in the hospital,” explains Dr Tan. “With minimally invasive surgery, you’re less likely to need long-term pain medication after surgery, and you’ll probably be out of the hospital and back on your feet much quicker.”

You’re also less likely to suffer from some of the complications associated with prostatectomies, like urinary incontinence and erectile dysfunction.

How long does a minimally invasive prostatectomy take?

Usually, the surgery takes somewhere between 3 – 4 hours, with 2 – 3 days in the hospital to recover.

What is the recovery period like?

Minimally invasive prostatectomy - Recovery
Your surgeon will insert a urinary catheter (flexible tube to funnel urine out of your bladder) to give your bladder and urethra time to heal. You’ll usually need to keep this in for 1 – 2 weeks after the operation, which is less time than you would probably need to keep it in if you had traditional open surgery instead.

You may also need to take some over-the-counter pain medications during this period.

What happens if I experience incontinence or erectile dysfunction after surgery?

While a minimally invasive procedure reduces your risk of complications, you may still struggle with incontinence or erectile dysfunction after a prostatectomy.

“Urinary incontinence (uncontrolled leakage of urine) is usually mild and will often improve over time,” clarifies Dr Tan. “Wearing protective pads may help during your recovery period. Your doctor should also be able to recommend some exercises to help strengthen your pelvic floor muscles.” If these problems persist, make sure to consult your doctor.

Meanwhile, the risk of erectile dysfunction really depends on your age, existing sexual function and swelling of the prostate. In some cases, the latter means nerve damage is unavoidable. However, your doctor may be able to provide treatment to improve this condition, so make sure you have a chat with them if you’re worried.

Are minimally invasive prostatectomies suitable for everyone?

Minimally invasive prostatectomy - Suitable for everyone?
In general, this surgery works best for patients who:

  • have early prostate cancer
  • have a life expectancy of more than 10 years
  • are fit for surgery

Patients with advanced prostate cancer, which has spread to other locations in the body, may not be suitable for this surgery. The same applies for patients who have severe scarring from a previous surgery.

“If you’re unsure of your options, the best thing you can do is make an appointment to speak with your doctor,” says Dr Tan.
