ADVANTAGES:
Since this is a minimally invasive procedure, there is relatively less pain and faster recovery compared to open surgery.
There is also less blood loss and shorter hospital stay.
Nerve Sparing Prostatectomy is accomplished with high degree of accuracy.
As with open surgery, this technique is highly effective and offers a high chance of cure from prostate cancer.
The patient will know if he is cancer free within a month after surgery, as opposed to up to two years after radiation. 
Because this surgery is minimally invasive, many of the disadvantages associated with open surgery are alleviated.
DISADVANTAGES:
This procedure is highly technical.  Most physicians performing prostate surgery have not been trained in this procedure.  Therefore, it is not available at all locations, requiring the patient to travel to an experienced surgeon and robotic surgery center.  It is recommended that these procedures be performed by urologic surgeons trained in oncologic surgery with extensive laparoscopic and robotic surgical experience.  It is recommended that the surgeon performing robotic laparoscopic prostatectomy have done at least 200 of these procedures.  The procedure should be done at centers of excellence, supporting high tech robotic programs.  Although adverse effects are rare, they could include incontinence, erectile dysfunction, possible formation of blood clots in the leg veins, and infection.

I hope this helps, if you have any questions about this, feel free to ask. If it is no trouble, would you also be so kind as to mark this response as the brainliest?
