The objective of the present study was to evaluate the safety of retroperitoneoscopic nephrectomy (RN) in obese Japanese patients.
We retrospectively reviewed 190 consecutive RN procedures performed from May 2002 to May 2006. We divided patients into an obese group (BMI >or=25, n = 54) and a normal group (BMI <24.9, n = 136). Operation time, estimated blood loss, and complications were compared between the two groups.
The mean operation time was longer in the obese group than in the normal group (203 vs. 184 min, respectively; p = 0.029). The mean estimated blood loss in the obese and normal groups was 127 and 91 ml, respectively. This difference was not significant (p = 0.39). There was no significant difference in complications and the open conversion rate between the two groups.
Although the operation time in obese patients was slightly longer than in non-obese patients, RN in obese patients was safely performed.
本研究的目的是评估肥胖日本患者行后腹腔镜肾切除术（RN）的安全性。
我们回顾性分析了2002年5月至2006年5月期间连续进行的190例RN手术。我们将患者分为肥胖组（BMI≥25，n = 54）和正常组（BMI＜24.9，n = 136）。比较两组的手术时间、估计失血量及并发症情况。
肥胖组的平均手术时间比正常组更长（分别为203分钟和184分钟；p = 0.029）。肥胖组和正常组的平均估计失血量分别为127毫升和91毫升。差异无统计学意义（p = 0.39）。两组在并发症及开放手术转换率方面无显著差异。
虽然肥胖患者的手术时间比非肥胖患者略长，但肥胖患者行RN手术是安全的。
