Table 1. Alternative techniques of robot-assisted laparoscopic radical prostatectomy.

Techniques	Advantages	Disadvantages & limitations
Extraperitoneal RALRP	Quicker return of bowel function	Confined work space, especially in smaller patients
	Lower incidences of ileus and bowel injury	Not suitable in patients who had prior laparoscopic placement of mesh for inguinal hernia
	Less steep angle of Trendelenburg	Cannot use Veress needle for insufflation
Retzius-sparing RALRP	Early continence recovery: immediate continence in up to 92% of patients	Increase in positive surgical margin rates (although not statistically significant in existing studies)
	Reduction in post-RALRP inguinal hernia	Formidable early learning curve, even for “expert surgeons” converting from transperitoneal RALRP
	Favorable in those who had prior laparoscopic placement of mesh for inguinal hernia
Modified Retzius-sparing	Early continence recovery	Single surgeon series only
	Minimal learning curve as most of the steps are identical to transperitoneal RALRP
