Extraperitoneal Laparoscopic Radical Nephroureterectomy and Lymph Node Dissection in Modified Supine Position

EL-RNU and EL-LND in the modified supine position are mini-invasive and feasible for patients with urothelial carcinoma in the renal pelvis or in the upper two-thirds of the ureter. Good exposure and dissection of the abdominal aorta and inferior vena cava and the integrity of the peritoneum are key to the operational success of this approach.
