title: Intraoperative cystoscopic stent placement in robot-assisted pyeloplasty: a novel and efficient technique.
abstract: BACKGROUND
  Robot-assisted pyeloplasty (RAP) is a minimally invasive approach for repair of ureteropelvic junction obstruction. Ureteral stent placement is a necessary step that may necessitate additional procedures and/or radiation exposure for placement and confirmation of stent location. These may prolong operative times and increase morbidity.
  
  
  METHODS
  Unique patient positioning and draping allow access to the urethra for intraoperative cystoscopy. As the surgeon performs the posterior portion of the Anastomosis, the assistant performs simultaneous flexible cystoscopy and retrograde stent placement. Stent location is confirmed by direct vision.
  
  
  RESULTS
  This technique has been performed in 30 consecutive patients without difficulty or complication.
  
  
  CONCLUSIONS
  This novel technique is a simple and efficient method of stent placement during RAP. It is performed simultaneously without the need for additional procedures, repositioning, or radiation exposure. Application of this technique may result in decreased operative time.
