Robot-assisted laparoscopic retroperitoneal lymph node dissection for left clinical stage I non-seminomatous germ cell testicular cancer: focus on port placement and surgical technique.

The aim of our report was to describe the feasibility of robotic retroperitoneal lymph node dissection in the contemporary era. We suggest the linear port location and 90° robotic docking as the main key to minimizing instrument clashing and improving the range of surgical accessibility.
