Robot-assisted laparoscopic retroperitoneal lymph node dissection with concomitant inferior vena cava thrombectomy for metastatic mixed testicular germ cell cancer: a case report.

This is the first case of robot-assisted laparoscopic retroperitoneal lymph node dissection with concomitant inferior vena cava thrombectomy and reconstruction for metastatic mixed testicular germ cell cancer published to date. This complicated surgical procedure was facilitated by the innovative usage of three-dimensional image reconstruction for defining the vena cava tumor thrombus, a robotic ultrasound probe for intraoperatively defining the vena cava tumor thrombus, and vena cavoscopy using a flexible ureteroscope.
