Effect of body mass index on perioperative outcomes for laparoscopic partial nephrectomy.

Journal Article

BACKGROUND AND PURPOSE: Obesity is becoming an increasing problem and is associated with increased incidence of renal-cell carcinoma. We sought to assess the impact of obesity on outcomes of laparoscopic partial nephrectomy for renal masses. PATIENTS AND METHODS: We retrospectively reviewed the pathologic and clinical outcomes from January 2004 through August 2010 of consecutive partial nephrectomies that were performed at a single institution. Patients were segregated according to preoperative body mass index (BMI), and outcomes were compared. RESULTS: Seventy-eight nonobese (BMI<30), 24 obese (BMI 30-35), and 24 morbidly obese (BMI>35) patients were identified. Obese patients were significantly more likely to be female (66% >35 vs 32% <30). Other baseline characteristics were similar. There was a significant relationship between estimated blood loss (P=0.03) and increasing BMI when compared as a trend. No significant differences were observed in regard to operative time, transfusion rate, complications, or surgical margin status between groups. CONCLUSION: Laparoscopic partial nephrectomy can be safely performed in obese patients without significant expected difference in outcomes.
