title: Robotic assisted laparoscopic partial nephrectomy for suspected renal cell carcinoma: retrospective review of surgical outcomes of 35 cases.
abstract: BACKGROUND
  A standard of care for the treatment of small renal masses is partial nephrectomy. The open and laparoscopic approaches have been well described in the literature. Robotic assistance may augment partial nephrectomy by aiding in dissection and renal reconstruction. In this communication we describe the surgical outcomes of 35 patients undergoing robotic partial nephrectomy.
  
  
  METHODS
  Patient records and databases were reviewed for 35 consecutive patients undergoing RPN. Clinical, pathological, and radiographic data were obtained. The data was deidentified.
  
  
  RESULTS
  Thirty five patients successfully underwent RPN. An additional 2 patients were converted to other nephron sparing procedures. Mean tumor size was 2.8 cm, and mean OR time was 142 minutes. Mean warm ischemia time was 20 minutes. All margins were negative. There were 4 complications, and no patients required reoperation.
  
  
  CONCLUSIONS
  Robotic partial nephrectomy can produce excellent initial results. Further studies should be performed to compare the outcomes to laparoscopic and open operations.
