title: Radical Nephroureterectomy Without Patient or Port Repositioning Using the Da Vinci Xi Robotic System: Initial Experience.
abstract: To report our initial experience on robot-assisted radical nephroureterectomy, using the da Vinci Xi robotic system without patient or port repositioning.
  
  
  
  The patients were in a modified flank position. A Bugbee electrode was used to cauterize and mark the ureteral orifice, aiding in the final robotic excision of the distal ureter. For the first step of the procedure, the second robotic arm holds the scope, the fourth robotic arm holds Port #1 (monopolar curved scissors), the first robotic arm holds Port #2 (Fenestrated bipolar forceps), and the third robotic arm holds Port #4 (Prograsp forceps). After completion of nephrectomy, all robotic arms were released and reconfigured. In the new setting, the third robotic arm and second robotic arm were switched between the camera port and the fourth port. The first port remained working with the monopolar curved scissors whereas Prograsp forceps was moved to the second port and fenestrated bipolar forceps was moved to the third port.
  
  
  
  Two patients underwent 2 successful radical nephroureterectomies with the above-mentioned technique. The console time for the first patient was 150 minutes whereas the estimated blood loss was 200 mL. The console time and blood loss for the second patient were 140 minutes and 300 mL, respectively. The hospitalization time and catheter removal time were 3 days for both patients and no complications were observed.
  
  
  
  The use of the da Vinci Xi robotic system enabled us to perform both nephrectomy and distal ureterectomy and/or bladder cuff excision without any repositioning of the patient or trocars.
