Port Placement and Docking for Robotic Surgery: The University of Southern California Approach

Abstract

Purpose:

To describe our approach for port placement and robot docking for pelvic and kidney surgery (KS).

Patients and Methods:

We use a four-arm robotic approach and a 5 to 6 port placement consisting of: One 12-mm camera port, three 8-mm robotic ports, and one to two assistant ports. For radical prostatectomy, the working robotic ports run parallel below the level of the umbilicus. Radical cystectomy ports are more cephalad and above the level of the umbilicus. For transperitoneal KS, two bariatric robotic ports are used, aiming for an equilateral triangle configuration. With retroperitoneal (RN) KS, a balloon dilator and balloon port create the RN space; bariatric ports comprise the most anterior and posterior ports.

Results:

This technique has been used since 2010 on more than 2370 robotic urologic cases. To date, no procedure has needed patient or robot positioning while maintaining fourth arm functionality with minimal robotic arm clashing.

Conclusions:

Our approach of port placement and robot docking is reproducible and feasible for pelvic surgical procedures and KS.
