Initial series of robot-assisted laparoscopic retroperitoneal lymph node dissection for clinical stage I nonseminomatous germ cell testicular cancer.

Robotic technology has enabled urologists to perform a variety of laparoscopic surgeries. Robotic surgery offers enhanced optical magnification and visualization with precise surgical movements. We report the first case series of robot-assisted laparoscopic retroperitoneal lymph node dissection for clinical stage I nonseminomatous testicular cancer in three consecutive patients. All procedures were performed using a modified template nerve-sparing approach. The mean patient age was 31 yr. Estimated blood loss was 150-200 ml; operative time was 150-240 min. Length of stay was 2 d, and there were no perioperative complications. This early series in carefully selected and well-informed patients represented a limited experience. These results may not be applicable to all surgeons. Further long-term follow-up with a larger number of patients are warranted to validate these preliminary findings.
