Robot-assisted laparoscopic partial nephrectomy in patients with previous abdominal surgery: Single center experience

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. Copyright
