title: Robot-assisted laparoscopic partial nephrectomy in patients with previous abdominal surgery: single center experience.
abstract: BACKGROUND
  The aim of this study is to report our single center experience with robotic partial nephrectomy (RPN) in patients with history of previous abdominal surgery (PAS).
  
  
  METHODS
  Medical records of patients who underwent RPN for a single renal mass in our center from 2006 to 2013 were reviewed. Patients were divided in two groups: those who had history of PAS and those without history of PAS. Within the PAS group, four sub-groups were considered: (a) remote site of PAS in relation to RPN; (b) PAS in the proximity of RPN site; (c) previous umbilical hernia/abdominal hernia mesh repair; (d) major PAS.
  
  
  RESULTS
  In total 627 patients were analyzed, and of these 321 patients had history of PAS (51.2%). On univariable and multivariable analyses, only Charlson Comorbidity Index, estimated blood loss, and tumor size were the significant predictors of complications.
  
  
  CONCLUSIONS
  RPN can be safely performed in patients with history of PAS with surgical outcomes comparable with those obtained in patients without history of PAS.
