Purpose: Our intension was to identify the influence of obesity on the operative results of laparoscopic renal surgery. Our study was performed on the basis of the body mass index(BMI).
Materials and Methods: Between March 2003 and December 2006, patients with localized renal cell cancer, who underwent a laparoscopic radical nephrectomy, were included in the study. The patients were divided into 3 groups according to their BMI: group I(BMI＜23kg/m2), group II(BMI 23.1-24.9) and group III(BMI＞25). Patients with abdominal operation or radiation exposure histories were excluded from the study. The study started at the time of operator’s overcoming of the learning curve for a laparoscopic radical nephrectomy. The operative data were retrospectively reviewed.
Results: Forty-one patients were included in the study. The mean ages of the three groups were 61.2±6.7, 58.2±6.1 and 59.2±5.7 years, respectively. The mean BMI were 20.3±2.6, 24.1±0.8 and 27.9±2.2 in groups I, II and III (n=15, 12 and 14), respectively. According to the degree of obesity, the operation time was meaningfully increased in group III(group I: 162.1± 39.4, group II: 147.5±17.5, group III: 199.4±2.2 minutes). The complications of a laparoscopic radical nephrectomy, including transfusion rate, had no relation with the degree of obesity.
Conclusions: For a laparoscopic radical nephrectomy, obesity could influence the operative time, but not the complications.
